i play in a modern/agressive rock band. i'm currently playing a line 6 variax bass, through an older fender bass combo. i'm looking to upgrade my kit. i think i've decided on the avatar b212 (after reading some good reviews), as my cab (they can build it to 4 or 8 ohms). and now i need a good bass head. any recommendations? i'm looking to keep it to $800, or less, but could be convinced to spend more. my "ideas" so far- swr workingpro 400 ashdown mag300h ampeg b2re ampeg svt3pro any recommendations would be welcome. cheers.
