Alright, i did a short, not thorough search and didn't see this thread, so here it is.
Hit us with your favorite amp. One per person. Can be two if you want to do a guitar and bass amp and why you love it so damn much.
For bass it's my verellen meatsmoke. It's mean, all tube super dirty and awesome.
For guitar it's tough, i have my strategy 400 which is only a power amp but everything i run through it sounds like satan. so that works.
Mesa Triaxis/Simul 2:90 for sheer versatility and grind. I can just as easily take it to a covers gig or metal gig or even jazz gig and get the tones I need with each guitar in my collection.
Bass however is a bit tougher as I mostly DI everything with a Sansamp Bass driver. But that through a power amp into my Mesa powerhouse 410 sounds fat.
