Hello i made a short sample of my g2, recorded with tone 60% and volume 45%...
the guitar its a ibanez AFS75 and a AKG c3000 microphone directly to celestion 10 speaker...a beringher eurodesk mx9000 mixer and a very cheap imic to tranfer the sound to my mac mini.....
im a very bad guitarrist 
but you can listen the sound of the g2...

Re: g2 tone noise (edited with some test)
Hi again eBernd:
yes sorry 5v from pin 8....my mistake.....
i test grounds with a tester and seem to be ok.....
some questions :
what its a shielded cable?.....
its normal that r1 (input) has ground in the two sides??
its ok that input and output jacks have ground in all the pins???....
thanks a lot for your help
Pedro
Re: g2 tone noise
Thanks eBernd for your answers and for your questions 
Yes the noise stop when i pull out the guitar..
i test all grounds and seems to be ok...
i do the conexions that show the manuals.....
i have the noise only when i use the tone & up the volume if i put the two in the midle i havent got noise...(in smooth mode) in fat mode the only way to dont have the noise its turn the tone all to the left)
the noise its a hi tone like the color bars in the video tapes....
i made same test:
from v1a pin1 to ground = 169v
from v1a pin3 to ground = 2v
from v1b pin6 to ground = 170v
from v1b pin 8 to ground= 2v
from v2b pin 5 to ground= 5v
from v2b pin 6 to ground= 242v
from r3 to ground = 233v
blue vs blue = 6v
i find out that if i low the tone in the guitar the noise stops and i can turn all to the right the tone in the g2 .....
if i plug only the cable without guitar i have the noise all the time
i´m sorry for my very bad english i hope you understand what i wanna say....
Best regards
Pedro
