I recently joined a classic rock cover band, and am wondering if a single 15 lightweight cab will be sufficient for gigs with minimal FOH support. I play a fender jazz in passive mode generally. Band has two fairly loud guitarists and drummer. Right now I have an Amp PF 500 into a single PF115HE, and am thinking of upgrading. I haven't yet tried this setup at a gig yet with this band. If you've gigged with this type of scenario, what are you using (cab and head), and would you recommend it? If you've added a second cab, please elaborate on what you used and how it benefited or detracted. No offense, but I'm looking for gig experiences, not at-home practice. I realize these kinds of questions come up fairly frequently in TB, but I've done a lot of searching and haven't found just what I'm looking for. Thanks all you groovy bass folks!
