Basically what I want it for is to even out my sound and add sustain for soloing. I have an eq running through my loop which I have set right where I want. However, sometimes when I hit the low E string it overpowers everything volume wise. And, adding some sustain and responsiveness to solos would be a plus. The pawnshop in our area has a BOSS Compression/sustain for $40. And, i figure that if it will help in all this and be something I can just leave on all the time why not?
