Been playing bass on and off for close to 50 years. Played double bass for a few years and recently returned to electric after reforming my 1977 band and now looking to upgrade my current rig. Over the years Ive tried many different combinations, good and bad, but my knowledge of current gear needs updating. I want a powerful head that can handle large venues, with 2 or 3 cabs that can be split for smaller venues and more easily transported. Mostly play a Ricky 4001 but also a vintage Fender Jazz and a dobro. Been chekcing out the obvious suspects, Ampeg, Ashdown, MarkBass and Mesa Boogie. I'd appreciate advice and suggestions, no cost restrictions....Im treating myself! Thanks.
