Hoping that the group can help me make a difficult decision. I believe I’ve decided on the Mesa WD 800 for my new rig head. I currently play with two groups one plays anything from jazz to country but mostly blues, light rock to heavy rock. The other is a trio that plays old Sabbath, Cream, and other heavy three-piece rock songs. I currently play a Fender Jazz Bass out of an Eden combo With 610 inch speakers. I would like to have two cabinets to fill the stage or the decent size practice room with this amp as we would rarely have any PA help in the gigs we do. Trying to decide between 212s one 12 or 115 or combinations. I know a lot of it just depends on what you want to hear yourself, but would be especially interested in combination of cabinets. The practice room has two flights of stairs so I am looking at the lightweight subway cabinets in particular or other lightweight cabinets that could pair with this head. I’m also 60 with bad knees! Thanks.
