I had been using a friend's MB115 as a practice amp with my band, and decided to buy an MB212 for myself to have something a little louder for small/medium gigs. I found one used and it sounded good at first, or maybe I just didn't notice it. Now though, it seems like it has gotten very harsh sounding and overly bright, even with the horn off. If I so much as touch the strings near the pickups you can hear it loudly through the amp. The MB115, using the same bass, sounds very warm and smooth and does not project the finger noise near the pickups like the MB212. I've rolled back the highs and high-mids a little and it has helped, but it gets a little bland sounding when I do. I guess I'm just wondering if any one else has had a similar experience with theirs. Are all of the MB212s bright and harsh? It's out of warranty, so I'm trying to figure out if it's the amps "normal" sound or if I need to take it in for repairs.
