What does it do? does it help the SS amp?

an abomination. It's like a BC Rich had sex with an Ibanez, had an abortion, and it survived on the side of the road eating roadkill and drinking it's own urine.

Most metal guitar ever. Period.
Typically they're designed to add the "warmth" that the solid state doesn't have. Or extra distortion.
Are we talking what the preamp in a solid state amp does or what a separate preamp would do with a solid state?
