Hi guys, Im a new user but have been following for awhile. Sorry to beat this dead horse. Usually I find the answers for my searches, but this one still confuses me about guitar tube amps for bass. If I am not worried about volume since (I will be playing in the garage) just the tone it gives me, I can use a guitar tube amp IF I match the ohms properly to the speakers? So would a 15, 20 or 40 watt amp and a 2x12 or 1x15 speaker cab be ok, as long the ohms matching up? Obviously I assume some amps will sound better than others. OR is it a must that I have to change the tubes and do other electrical work??
