The COSM emulation on the GT-8 is an attempt by BOSS to emulate great amps. So the GT8 is actually a solution for us poor guitarsits who cant really afford all those great amps. I use a MG80RCD, which is a solid state amp, and I generally turn of the COSM emulation anyway (To me it hardly ever sounds really good) But the effects patches on the GT8 are great, you just need to spend quite a bit of time configuring them. I usually bypass the COSM (and the pre-amp for that matter) and just use the effects.

Vick just a question... how does the GT-8 sound through the MG amp? I have an MG amp, but have been told that a Boss effects pedal would be wasted through a solid state amp!?!
