Praise and worship bassist here. Don't need a big combo amp or anything: I'm guessing 30W or even 75W should be MORE than enough. I have a few I'm interested in Fender Rumble 30 or 75 amp Ampeg - BA-112 - 1x12 Bass Combo Ampeg - BA-115 - 1x15 Bass Combo OR should I just use my Tech 21 Programmable BDDI even though the speakers kinda suck? Is it kinda overkill using the BDDI in a small-room setting? I hazard a guess it could fit like 100 people comfortably..
