I just got myself a new Turbo Rat pedal to replace my old one that finally broke down (after 15 years of abuse).
I just want to sing its praises. I really only use it for when I play solos, or need some extra OOMPH like that for a radical dynamic shift.
It is the freaking bomb. It's the only effect that I use (aside form reverb) and it's all that I really need, outside of pickup selection.

Nasty, nasty, nasty.

Almost got an Ibanez Tube Screamer (I know that some of you will sing the praises of that green monster), but I had to stick with what I already know and love.
