Bass parts will be played by me, a guitarist, for a recording project in Allman Brothers style. Using a P bass with passive electronics; going direct for recording if possible. Am I splitting hairs, or will there be much of a difference for this application? What about gigging (this possiblity may not be very likely....); I have an Eminence 15 I found by the side of the road, the fine folks in Ky say its a bass speaker, and a no-name 12 with an f of s of 5 that came to me as a replacement in a Peavey Bandit (!?)
