I have a 1x15 (I believe pre-Gibson) 7-band combo amp. It has a jack to add an extension cab, but I've never gotten around to adding another cab. Is it worth the extra $$ and sweat carrying it for the improved mids and highs? Is suppose that it's subjective, and I have a tendency towards GAS. My thought would be to add a 2x10 cab of some form. I'd love to hear from people playing similar rigs and get recommendations for extension cabs. I haven't shopped for amps or cabs since I bought the TE in 93, so I'm not up on the newer gear. Thanks, Sean BTW - If it matters, I play a j-bass primarily and sometimes an old Guild Pilot w/EMG's.
