Need some expert opinions. Been playing a few years and consider myself an intermediate player. I like fingerpicking and slapping. Ive always owned low-end basses and am tired of loud, boomy E's and lousy playability above the 12th fret. I want that great 'boingy' sound and something more playable. Im leaning towards buying a Rick or MM. The catch is I dont want, or have room for, a large expensive setup. I dont have access to these finer basses locally, So my question is: Is great or good sound achievable by plugging a quality bass directly into an Ampeg B-50? or should I stick to my ErgodyneEDB-500 since Im not willing to upgrade my setup? Would an OPL-MM be a noticeable sound improvement and more sensable purchase? Ive read the mixed reviews on OPL's. Advice greatly appreciated.
