I have recently bought a Fulltone GT500, which is a great sounding pedal. However, when I engage the Booster/OD side I get a lot of background noise and feedback. It doesn't happen on the Distortion side of it, only on the Booster side. I have been able to dial it in and tweak it to limit this, but i'm hoping there is a way or technique to do this further? I don't mind a bit of hiss and noise when not playing, however it is a little on the loud side. I've heard about smartgate pedals and i'm wondering if this will help reduce this sound without effecting the tonal qualities or volumes of this pedal and other pedals in the chain. Any help would be great!
