Hi guyw and have a happy new year , i built one of this pedal for a friend and i have a very unusual problem , the pedal woks great on my hiwatt ( i used TL072CN ) but when my friend try to play it on his amps ( a marshall and a mesaboogie) the pedal works great when in buffer mode but when engaged it has a very big hum and noise when he just open a bit of the volume .
have any of you experianced any similar prolem ?
thank you very much
