Good Morning ladies and gents! Just like the title says, I'm in a position where I'm going to be upgrading both my amp and cab in the relatively near future, but I wasn't sure which to upgrade first. I tried searching for similar threads and reading other threads to pull a relatively consistent opinion therefrom, but to no avail. A little background- been playing about 12 years (I'm 28 now). I've never owned a tube head before, mainly due to high price- it's always been solid state, with which I never had a problem (aside from variably lackluster tone). However I recently got out of a project/studio that had all quality gear which sounded noticeably awesome'r, and I decided I wanted to bring the level of my personal rig up. I guess you could say I got spoiled. I currently own TB's favorite, a Behringer. It's the ultra bass bx4500H head that came with the included 4x10 cab loaded with TB's next favorite: Bugera speakers. Ive used this rig mainly for playing in a metal band for years, and for a bit as a guitar cab. I don't hate the thing, but obviously the harder you push it and louder it gets, the less desirable the sound becomes. My question again- do I upgrade the head first or cab? I don't know enough about amplification in general to know which is a better route: A) Getting a better head and pushing it temporarily through a lower end cab, or B) Getting a better cab first so that the new head, when acquired, will have an appropriate vessel through which it can flex its muscles. Here's how I see it: I figure getting a cab first could improve how my current head sounds. But I'm a proponent of "garbage in, garbage out" so I could also see how getting a cab first could be likened to polishing a turd, yielding only minimal sonic gains. Conversely, getting a head first addresses the "garbage in, garbage out" philosophy, but I feel like you'd have a tone bottleneck of sorts. Running a great sounding head through a low end cab would (according to my limited understanding) lower the quality of sound coming to the ear, relative to the head. I don't know how flawed my logic (or lack thereof) with this, so I'm hoping to receive some guidance. Your thoughts? EDIT: This rig would be geared toward a jazz/bluesy type band, as opposed to the metal I refer to below.
