I'm thinking a Shiva (EL34) or a Mesa Lonestar. I like the qualities of the C30 but I want a more harmonic, dynamic and rich sound. I don't mind using a boost on the distorted channel for leads and heavier sounds. Any recommendations on two channel amp with a killer clean and a good marshall like overdrive channel that takes pedals well? Remember C30 upgrade. I use humbucker strat style guitars. I would prefer an amp with an efx loop works really good. I know the Shiva has a loop problem, but understand the new model fixes this problem. I need to stay under $2000 for a head and 2x12 (or 1x12 combo).
