Ok here's my dillema. Right now I play a Hartke 3500 w/ a hartke 4x10. And have a Fender Aerodyne Jazz Bass(love it)My guitarist plays a Mesa 4x12, also with a fender Aerodyne(not that that matters) but what does matter is that I can't hear my self. Thus I need a new amp. I would like the Fridge sized ampeg 8x10 with the SVT 4 amp. (basically my dream amp) But our drummer is trying to convince me to go avatar. I called Avatar to talk to them about it and decided on.... The SVT 4 amp... It comes down to either the 8x10 Ampeg or 2 4x10 Kappa Pros. I have never played through an avatar but have never heard a bad review. I have played through the Ampeg stack and loved it. Can anyone give me insight on the difference between the two amps. I tend to play alot of highs and lows at the same time I.E. 4 diferent octaves at the same time, Chording with tapping, and guitar parts on the bass. Basically I need something that will be able to give a wide range of sound while being heavy and punchy as hell. Deep lows, clear highs, and still able to knock you back from 20 feet away. I currently have about $1,500 to work with but am willing to spend up to $900 more.
