I need a grab and go 1x12 combo that is loud enough for gigging, that will have enough headroom for jazz, and that will be very verstaile, without breaking the bank. mesa F-50 - good cleans, plenty of gain, loud, but the OD might not be the greatest zinky blue velvet - very good OD, decent cleans, only 25 watts, questionable headroom traynor blue 50 - good cleans, good OD, not too expensive, but overall quality of sound maybe not as good as the other two. Maybe not enough gain too. peavey valveking - very cheap, widely available, but the sound might not be close to the others. rivera ____ - great cleans, bad OD. I probally will be buying some OD pedals to help with any tones I can't grasp. Anyone with expirience with any of these, please chime in. Its the headroom and cleans that Im really concerned about.
