cuz that thing farts all the time. it's an avatar 210 neo. i have a traynor all tube head. at show volume, anytime i get down below A, things get real fuzzy real fast. i'm not a superknowledgeable guy when it comes to amps, but i don't understand how a 200 watt bass head is overdriving a 500 watt cab. it's just a passive four string. should i be looking into a 15" instead? any help would be tremendous.
