I need to get a small amp to play through for a more traditional music service at my church. This is necessitated by a need for me to move away from my main rig over to an acoustic piano. I've been given a budget of under $400 and I'm looking at an Ampeg B112, Fender Bassman 60, Hartke Kickback 10 and SWR Workingman 10. Which will do the best job for me. I will also take it home as a practice amp.
