Ok I'm a first time poster, so here goes... First off I'm a poor college student that is building a rig, I have this tube amp called the Carvin MTS, I love the tones I get from it but I want a little more gain. I have high gain tubes in it and I own the standard sd-1. The sd-1 is a nice pedal but it colors the tone and you know how annoying it is to get your perfect tone then have to re-adjust. Also its kind of annoying to have to switch it off when I go to the clean channel. So I was thinking clean boost since my amp in non master volume it would just make the clean a little louder and more gain on the lead channel. I'm trying to keep it under 100 usd, used is no problem at all.
