If you first stick with the fabric settings you will see results (from more pain, herx to feeling a bit better or pain to no pain)
The fabric setting is 5 minutes per 8 frequencies low or 2 frequencies high.
Using only the GB4000 on RF (without amplifier) over hand and footplates can be hard, if you do it full power, the machine chokes on some frequencies.
The GB as stand allone with RF function is however very suitable for local use on scin dissorders or in other local treatment.
If you only want to use low frequencies like the Crane and CAFL frequencies, you can not use the 10W amp but the output of the GB is very strong!
I use to use this setting for muscle pain and less serious things.
Most of the time I use the GB with Amp over the whole body, but in cases of intestinal problems and cleanings I use the foot pads over the treatment area front back, like liver etc.
You best use the wet cloth covers, if you do not, there is a chance for little burnings!
So good conduction over the pads is a pre.

In have only been experimenting so far with the duty cycle, it seem that Rife High frequencies can be better run with a duty cycle of 50% instead of the fabric setting of 90% (wich works best for all low frequencies.

Earleir tests of John Crane have proven that even Crane frequencies can be effective, the builders of the Crane Audio device however did fabric a bad product, and this may be the main reason why the Crane frequencies work less good or not at all.

There has been a very unfair frequency trade, so that effective frequencies were sold to the highest bidder. Even the inventor of the FSCAN models was a victom of that traders, but also had done his homework very bad: There are no low Rife frequencies.

Once you have the universal frequency list that comes with the GB, it will get clear that the builders must almost have known Rife or real Rife asociates.

Even if you look very hard, you will not be able to discover but only a few original Rife frequencies, all calculated down to Herz, while Rife only used cycles per seccond. Some notes that are found contain more that 3 differend kinds of handwriting, so even if it were original Rife notes, what of the 3 hands was from the real Rife?

I still think (after a study from 1997-2003) that the GB4000 is an affordable machine that even Rife may have aproved (or build).

I have no vega test, no microscope and lack a lot to make my own diagnose, so I have to rely on the information that people give me.
If you treat a local strep infection with staph frequencies the effect can be a lot less than expected.
But in most cases that the GB4000 has no effect, the information and diagnose are wrong!

I received an attachment with interesting information to use the gate option with the curing cancer frequencies. On the other hand I have a problem with it, the gate values are 2008 and 2128 Hz and these are Crane related, and therefore not my first choice. We have no practice that get 10 cancer patients a day.

The maximum time I have used for treatment with the GB is 30 minutes, but that is even for a GB doing lets say 24 frequencies 1 and a half hour.
In some cases you have to treat long and often before you see results, but that is because 10 W is a lot less than the original power used by Rife.
It depend on age and condition to choose a daily or once in 3 day schedule.
On acute infections (most intestine) I go on untill I see relief, and repeat the sets that give instant relief, untill most of the sympthoms are gone (like pain nausea diarea etc).

With a choice of over 800 conditions, without a good diagnose, working with a GB can still feel like a needle in a haystack.
