What's up? I have taken the head out of my 20w combo amp and want to use it as a fuzz effect (it's incredibly blown out) on my larger amp. I would have to run into it's input then out it's headphone jack into the input of my larger amp. However, when I do this, the volume is greatly reduced. I am also scared that since the headphone jack is powered, it might overload my amp. Then I saw the EBTech Line Level Shifter in Musicians Friend, and it looks like the answer to my prayers. Does anyone have info on this product? Will it doo what I need to do? My larger amp also has a preamp out and a poweramp in on the back, but I don't think the poweramp in works. I am soon getting a preamp/poweramp set up, so I was wondering if I could run this in the effects loop. But, again there is the loss of volume. Thanks alot for any and all info.
