I know that there is some great info on the below subject in various places, but I am looking for some help in chosing a new amp to pair with my two Berg AE112(B) and/or my Berg AE210 vertical. I do not want to change cabs (except maybe a CN212) but am looking to mix it up from my present GB SL900 (sometimes too pillowy) and my TH500 (sometimes too aggressive). I had a GK MB 800 but had some issues with it. (another story) Anyway, I was looking at either a GB Shuttle 6.2 or 9.2(had a 6.0 and it seemed to lack lows) or a MarkBass LM3 or Big Bang. I do not have access to try these heads so I am looking for the experts (Ken are you there) to provide some guidance. I plan on keeping the present GB and TH but just looking for something that will work with the Bergs for mostly classic rock fingerstyle playing and might fit somewhere in the middle of the SL900 and TH500. If you tell me I am nuts and should just work with the present setup, I am OK with that too!
