GB-4000 Rife Machine Experiment

As I have begun experimenting with a GB-4000 Rife machine, I put together some notes on how the machine works.

Usage Time

I experiment with its use 2-3 times a week for maximum 30 minutes – 3-5 minutes a frequency or “Sweep” (see below). The average time seems to be 30 minutes a session for others experimenting with the GB4000, although some go as long as 2 hours at a time. Many have reported that when experimenting with the GB4000 for bartonella, they need to use the rife machine twice a day.

GB4000 & SR4 Amplifier

The GB4000 puts out the frequencies and the SR4 Amplifier increases them. The GB4000 itself has 2 power supplies and 2 cords. To connect the GB4000 to amp, one end of the short black cord with two male ends goes into the back of the GB4000 and one end into the back of the amplifier. The larger black power cord plugs into the amplifier and the 2 small power cords go into the back of the GB4000. The cords are connected to the GB4000 power supply and then to a surge protector. (Cord that connects to amplifier power cord is harder to connect so I needed to push in hard). A SURGE PROTECTOR MUST BE USED OR THE MACHINE CAN SHORT! The dial on the GB4000 needs to be turned all the way down (meaning, all the way to the left – counterclockwise) before the machine is turned on so that I don’t get a large jolt of energy. Once everything is plugged in, the machine is turned on by flipping the power switches (red) on both the GB4000 and amplifier.

Audio Mode vs RF Mode

The GB4000 is in Audio mode when it is running without being hooked up to the amplifier, as opposed to the RF mode. You can tell the machine is in Audio mode as there will be a large A at the top center of the screen. RF mode is the default on the GB4000 and is what most people use to experiment with which is why the amplifier is needed. *When using the machine in Audio mode, the SR4 amplifier MUST be completely disconnected from the GB4000. For the RF/Audio button, if you press it once it will show you what mode you are in and if you press it twice it will change modes. Using the GB400 without the amplifier will always be in Audio mode.. To turn off the GB4000, turn the knob all the way off – counterclockwise – and hit the red power switch. To turn off the amp and GB4000 when using them together, do the same thing, except after turning the power knob all the way down, first turn off the amplifier by hitting its power switch, and then hit the power switch on the GB4000.

Hand Rods & Foot Plates

2 hand cylinders with blue cotton cloths and 2 foot plates with blue cotton cloths. The two red 2 cords plug into the handle cylinders. Cloths always need to be moistened well with warm water so there is greater conductivity – not dripping wet. When using the GB4000 without the amplifier, plug both of the hand rod cables into the 2 positive out spots on the machine (red), and then plug the cord which connects the foot plates into the negative out. When you connect the black cables to the foot plates, connect one side of the clamp to the actual metal foil and the other side of the clamp to the blue cloth that covers the foot plate or else you won’t get conductivity. When using all four together (hand and food rods/plates – recommended), it , in a sense, turns your body into antenna. When using the GB4000 WITH the amplifier, you connect the two red male ends of the hand rod cords to any two red positive female spots on the amplifier, and you connect the black male ends of the foot plate cords to the two female black negative spots below the red spots you are using for the hand rods – you don’t connect the hand and foot rods/plates to the GB4000 itself when using the amplifier!

Sine vs. Square Wave

Machine defaults to square wave for lower frequencies and automatically changes to Sine wave if the frequency being run is over 1 MHz. However, it is suggested that you change the wave to Sine if you are doing frequencies between 100,000 KHz-1MHz. If you press the “Sine/Square” button once it will show you what wave you are using. You press the “Sine/Square” button twice to switch from one to the other. The machine cannot do Sine wave when in Audio mode– Sine wave is for higher frequencies. The only time you need to change to Sine mode is when running frequencies less than 1MHz – it is important to only switch to Sine when using frequencies in the AM range 100,000Hz-1MHz as the machine will automatically switch to Sine wave when you are using frequencies over 1MHz which is what needs to be used always for those higher frequencies.

Duty Cycle

There are two places where you use the duty cycle. The “Duty Cycle” of the square wave is by default set at 90% (low frequencies use the square wave) which you should keep it at. 90% duty cycle = more power delivered. The duty cycle will always stay at 90% unless you change it. To change the duty cycle of the square wave, when machine is on, press the decimal point button and enter whatever number you want the percent to be and then hit the Enter button to set the overall Duty Cycle of the square wave. The duty cycle is the percentage of the on pulse versus the percentage of the off pulse. In square wave you have a very steep uphill on pulse and it is theoretically an instantaneous on pulse where it reaches peak of that wave instantly and it’s going to stay on for whatever the duty cycle is set at and that percentage by default is 90% and then it’s going to go off for 10% of the time. The off pulse is a very short period of time compares to the on pulse and this can be adjusted. So a 50% duty cycle means the on pulse is the same as the off pulse which delivers less power to the user of the machine. This is very distinct from the duty cycle of the gating feature which is discussed below.

Then there is the duty cycle for the gating function and this has nothing to do with the above duty cycle. The gating duty cycle is the width of the square wave when running in square wave – the gating duty cycle cannot be set with running in Sine wave and if you try to do so it will prompt an error message. You control gating with the “duty cycle” of the gating which is different for the overall duty cycle of the machine. Which duty cycle is more effective? Some say 25% others say 50% and he feels it is 50% as it seems a better setting because there is more energy getting through the gate. The duty cycle is accessed by pressing “Gate” button and then pressing the number 3 which gets into the gating settings. The first setting that comes up is the frequency and when entering it after that the duty cycle comes up and that is when you enter the percent you want (this percent duty cycle will be saved for every time you use gating unless you go in and change it).

Running Single Frequencies

To run a single frequency (which is always defaulted as running at 5 minutes) hit “enter” button then punch in the single frequency and hit “Run” button. Hit “clear” button to stop at any point. To run a single frequency for less or more time than the default of 5 minutes, let’s say you want to do only three minutes, first hit the number 3, then the “Enter” button and then type in the frequency and hit the “Run” button. To run a high single frequency, let’s say I MHz, you need to type in 1,000,000. When running a single frequency you will see that frequency on the screen.

Running Auto-Channels (programs)

To run, let’s say the 205 auto-channel (in the instruction booklet that comes with the GB4000), press “Auto-channel” button then enter the numbers 205 and then hit the “Run” button and the machine will run all the frequencies in that auto-channel. The ‘G’ on the display screen means there are 5 groups in the program or sequence. Therefore, it will be a 25 minute session because it’s defaulted at 5 minutes per group and it is 5 groups in this case. On the right bottom side of the screen it shows the counting down on the first group – G5 will show then G4, then G3, etc. To change the time a group runs, let’s say you want each frequency in a group to run for 3 minutes, instead of pressing “Auto-channel” first, you would press the number 3 and it will say duration, then you press the “Auto-channel” button and then enter the Auto-channel group number – let’s say it is 205 – and then you hit the “Run” button and now it is counting down each group from 3 minutes – each group will run for 3 minutes. On the screen, the word “multiple” means that it is in multiple frequency mode so it is running a number of frequencies at the same time – there are two different modes and “single” for running single frequencies vs multiple for running “multiple” frequencies.

If you want to run a few sequences one after another, press “Auto-channel” let’s say 204 and instead of pressing “Run” button you would press the “+” button and enter the next sequence, then you can press the “+” again or press “Run” to start. You can enter as many sequences in a row as you like.


The Gating feature was originally designed to run with programs that were running higher frequencies. Now gating is designed to affect the wave form creating sharp voltage spikes that disrupts the organisms more. These sharp voltage spikes can change the harmonics of lower frequencies. You need to turn “Gating” function on every time you turn off and on the machine if you want to run a frequency or an auto-program with gating. Hit “Gating” button than number 1 and it will turn the gating function on. When doing an auto program (a group of frequencies that are pre-programmed) pick one frequency in the program and “gate” it at that frequency. Or look for a common frequency to gate that is common to targeting the organisms you are going after. For low frequencies, Gating at 4-5 Hz can help. Gating is geared more toward higher frequencies though. The GB4000 will only “gate” 5-2,200 Hz (this is separate from whatever frequencies you are running) – this is just the “gating” range you need to enter. He picks a common frequency from frequency list that is common to what organisms he is going after then he gates at let’s say 728 or a harmonic of that frequency when doing a lower frequency program. Turn on Gating before you get into doing sweeps. Again, gating affects the shape of the wave form and is especially important for higher frequencies.


A “Sweep” will automatically waver the frequency 5% above and below whatever the frequency or frequencies are you are running. This was originally called the “Mutant” feature as it was designed to address the issue of mutating strains of bacteria or other microorganisms, pathogens. There are two “Sweep” options available. One is to run a “Channel” sweep which is a convergent sweep and the other is to run a regular “Sweep” – two different green buttons – and they do two completely different things. A Channel sweep start at both the high and the low frequencies and sweeps to the center. He advises against convergent sweeps because it splits the power between the 2 frequencies. There are a number of “Sweep” frequencies outlined in the manual. They need to be run manually and are not part of an auto-channel program.

If you press the “Sweep” button it will prompt you to do your sweep but if you hit the “Channel Sweep” button it will appear not to do anything. Therefore, to run a channel sweep, let’s say with auto-channel 205, first hit “auto-channel” then enter 205 and then hit “Run”. If you then press Channel Sweep, a CS will appear on the screen so the Channel Sweep is something you press while the program is running.

To do “Sweep” hit “Sweep” button and enter duration. If you want to change the time of sweep first enter the time, say 10, then hit “Sweep” button. If you hit “Sweep” it will default to 5 minute sweep but if you want a 20 minutes sweep first punch in the number 20 then hit the “Sweep” button and then enter the first frequency you want to begin sweep at and then hit “Enter” and then punch in the end frequency and hit “Enter”. The screen will say hit 1 (standard sweep) or 2 for channel or convergent sweep. He always uses standard sweep.

    I have the GB4000 and the DVD and manuals give all the “how to’s” as you just explained but NONE of the whys. Why have RF vs. Audio, why gate it, why square vs. sine, why do a convergence – there is no info on the Internet that deals with the WHYs!

      Hi Tom,
      I too have been frustrated over the lack of ‘why’ to many of these features/functions…It seems like the people who built certain modern “Rife machines” are trying to follow as closely as possible what Royal Raymond Rife used for the original Rife machine – basically, use it this way bc that is how he used it and how he had success in treating illnesses based upon writings and such people have found. So you’d have to buy into the validity of this and then everything follows from that. If you Google Royal Rife and some of your questions you may happen upon some answers – “The most important feature to look for is a Rife unit using a RF carrier (Radio Frequency). Royal Rife and Hoyland used RF which was a big part of their success. The reason is very simple: the audio frequency range is carried further with a high frequency range generally in the meg range. Certainly, any frequency over 1 meg is in the range that can be used as a carrier wave. Most units on the market today don’t use RF.”

        Danielle you are providing a great service here. I have been having HUGE success with a wide range of treatments, and I agree with pretty much everything you uave said here. I am a military trained electronics person and have been studying alternative health (including Rife) for about 30 years. Bought my GB last year and haven’t looked back. I may be able to answer some of your or your followers more technical quations so don’t hesitate to ask. Everyone is just so scared of the idiot “authoroities.”

    Hey Danielle,

    Getting back to Tom’s question. I’ve got a GB4000, and played with Audio the other day. It felt like I was being elctrocuted. hahahah. Can I run audio and get a herx? Have you done JUST an Audio session, and had any success?

      Hi Andrew,
      Wow, that is a strong reaction! I did have some herxes from running it just on Audio, and did have improvement just on audio as well, although using the the amp with the Gb4000 has helped even more.:)

    I have been reading with interest about your Rife experiences. I am do diagnostic ultrasound. Your conversation made me wonder if just ultrasound might be helpful. I know that I felt the best I had in a long time following a brain MRI last spring. So I am going to try transcranial ultrasound on myself. I’ll let you know how it works. It is more in the 1.5 MHz range and higher.

      Hey Jessica!
      I am seeing continued benefit since beginning with the rife and being off of abx. Still have some symptoms that aren’t budging, but I only began using the rife on full power and some other features about 2 months ago, so I am feeling encouraged.

      Wishing you the best in health,

    Thanks for all the info. I recently started using the gb4000. Do you use the pre-programmed frequencies, or are you trying Brian or Doug’s frequencies? I’ve been trying the group for primary Lyme..can’t tell if I’m having die off or symptoms.

    • Danielle
      January 30, 2012 at 10:55 am

      Hey Rick!

      Certainly. I have been trying Brian and Doug’s frequencies. I used the autochannels (group) a bit, but find the single frequencies to be more beneficial.


  6. June 25, 2012 at 2:59 pm

    Does anybody know where this machine can be purchased?

  7. July 12, 2012 at 4:29 am

    Thanks Danielle.

    Have you improved any? I would love to hear about your progress. I too notice that in Late Stage Lyme antibiotics are NOT the answer for most people.

    Im considering buying the Rife for help in my cancer treatment. Anyone have suggestions or comments? There are so many things to buy. Seems like everyone has something to sell.

      If trying to cure cancer, definitely look into the Gerson Therapy. Change the way you eat, and eliminate cancer. As far as Lyme Disease goes, I know there’s a company in Tarpon Springs Florida who’s making a device that can cure cancer, MS, Lyme Disease, etc. Their website is: Their ultraviolet light theraphy can kill bacteria, and possibly even cancer. If I remember correctly, Rife said that cancer goes through various stages of metamorphosis, and it’s the result of a fungal infection. If true, this device could potentially kill the fungal infection, and thus eliminate cancer.

      Unless you are some kind of scientist, you should know that the machine is very difficult to use because there are no clear definitive instructions. The book will give you a range of frequencies to chose from, but they won’t tell you what any of the gauges do or why, there’s a button and a dial on the MOPA that I still don’t have any idea to turn off or on or what setting. If you have a scientific background then go for it.

    Hi Danielle,

    I just bought a GB400, mostly for the purposes of treating my Lyme patients. As I flip through the manual, I see that there are 2 standard channels for Lyme, as well as many adjunctive frequencies, which are ancedotal.

    Which channels/frequencies would you suggest that I start with? Thus far, I have been running channels 466 and 467, for about 3 minutes per frequency, though none of the 10 patients that I have treated thus far have noticed any herxing. I have the intensity all the way up, it’s in sine wave, with the gating on….with the amp.
    Any suggestions? Thanks so much. Emily

    I have a gb4000 with Mopa. There is very little instruction or explanations anywhere. Can’t somebody explain it in simple form? I’m less concerned with the why – I just want to know how. I thought by buying a machine already built I could just be given instruction that would just tell me exactly what to do – this is how you turn on and off, this arrow should point to this number, this lamp turns on now, this button tells you this. What’s the counter button for?, what’s the frequency dial? What’s a channel? Then I could just select the “number” I choose to run, follow the instructions and be done in five minutes. Not spend two months reading everything and understanding none of it. I want a user guide for dummies – any idea where I can get this kind if help?
