Hey Everyone,
I have a Supersonic 112 and I placed my compressor in front of my amp today (used to run through my fx loop) and when not engaged, there is a loud squeal when I turn the tone up on my guitar. When it's on, the amp is sounds fine. I wanted to place it in front of my amp to see if I could get a cleaner compression because the compression was increasing the volume of my fx loop, which I didn't want. So I'm guessing a pedal thing...hopefully. Wondering if anyone else has experienced this. I play a Tele Highway One and normally the amp is no more than 4 in volume. Just never had this happen. Hopefully nothing serious. Thanks.

Hi pa2702,

It may be a preamp tube that's microphonic. With the pedal in the effects loop, it's after the preamp tubes. With the pedal in the input jack, you're going into the preamp tubes. :idea:

Por favor, disculpe mi español, no se llega a la práctica con mucha frecuencia.

Thanks shimmilou, Yeah, I do like the compression in front of the amp so I double check my pre-amp tubes. Thanks again!
