Hi TB, this is my first post here. I started playing bass back in early February, when I got my first bass (Tagima TJB4 Jazz-style bass) and a cheapo no-name 15-watt combo practice amp. Recently, I've been looking to upgrade my amp and buy a nice second-hand unit for a better sound. So far, I've found the following models in my area, all roughly the same price: Hartke A70 Hartke A100 Hartke HD75 Fender Rumble 40 (v3 model) Fender Rumble 75 (older Rumble model) Fender Rumble 30 (older Rumble model) Peavey Max 115 (60W model) Any thoughts on which unit might be the best? Pros and cons for a specific model are greatly appreciated. Any other particularly interesting amps that you think might be worth tracking down? Thanks!
