big problem there. there is an unpleasant noise stanby.
Another worry: when the pedal is plugged in series with the transformer and you do not connect any jack on the input and output. it causes interference to your amp.
I explain: you have your guitar plugged normally on your amp, you plug the Pigtronix on a socket without placing jack whenever you touch it with his hand a high background sounds in your amp. then it is not linked up to your system. I think there is a big problem of interference with their food. shame because the sound is exellent. RVG
Buzz spoil the sound of this pedal.
I went to the seller. this noise problem is too important. I hesitate to buy this brand despite its qualities and possibilities of their pedals.
