Yeah sorry there is only 20 slots for this. Which company would you like to endorse? These options were based on of course the known ones, musicians who already endorse them, and some just off forums here at TB. Sorry if you're other. I did the best I could. I think I'm would say Ampeg right now but I really like Mesa Boogie, too. Help me decide. I'm gonna let you vote for multiple in case you want a certain head with a certain cab or whatever. OK I'M TRUSTING YOU GUYS TO VOTE FOR 1-4! I don't know why you would need 4 in the first place. I'd prefer you vote for 2 max. Note: We're talking about endorsement for your amps and/or cabinets, not basses.
