i recently got a 1x15 beta bass combo in a trade. the speaker is shot but the amp is in good shape. i already have a silverface concert bass and don't really need 2 bass heads (even though i've been using the concert bass for guitar, i'd like to have seperate heads for bass and guitar) so i was wondering if anyone would be interested in trading a concert lead or any other sunn guitar head for the beta bass head. pm me if interested and we can work something out. thanks!
