UTILIZATION

I spend the boss gt-8-pro gt no difficulty as it is the same thing except in rack version with a little more connection!

the manual is really screwed up!

and soft gt-pro simple and complete editor!

SOUND QUALITY

I use the gt-pro with the 4 cable method in an orange rockerverb100
I use mainly the delay / chorus / flanger / reverb / EQ in the loop of orange
and wha upstream of orange

one default function whammy is so-so ...

I also use the simulator if acoustic guitar and it really giant!

OVERALL OPINION

I use it for some months he found a place in my home made rack without worry!

I test the pod / Vox ToneLab / G and zoom boss is doing for me hands down!

The value for money and correct (especially since I got a 350 euro nine ... hehe)

yes I do it again this choice without hesitate
