Hi all. I asked this question a few days ago and got a couple of answers, but i've broadened it a bit and am throwing it out again to see if anyone else has some relevant comments for this newbie. I jam with a group of late beginner / early intermediate, totally acoustic musicians -- 3 guitars (me being one) & 2 (bluegrass) banjos. We play almost exclusively for ourselves -- no gigging. We occasionally have trouble hearing the beat with this mix, so i volunteered to learn to play bass guitar to provide a clear beat and to provide some bottom to our mix. I bought an Ibanez Mikro bass and an Ampeg BA-108 after reading a variety of comments on this list. Although i know this combination will serve my needs, i'm frankly somewhat intimidated by the size and weight of the 108. I'm wondering whether a 10 watt amp such as the Peavy MAX 126 or the Ibanez 10B has sufficient power for my fellow jammers to hear the bass clearly over their own instruments. Remember, the bass will be the only amplified instrument. Thanks for any experience you can share.
