Tossing around the idea of a lower wattage amp and was looking at the Dr. Z Carmen Ghia, Maz 18 JR NR or the Z28 amps. Which Z is best for blues and some blues-rock and matches well with a strat and gibson 335? Which speaker combos too should I consider?? 1x12, 2x10, 2x12, Z cabs versus others, open backed versus closed? Which ones take pedals well, which ones dont... Portability, great sound at low and high volumes are key..
