hi fellows...i play an older svtII thru an 810 and that's the sound for me--but it's a large, heavy sound! i'm looking for a very small, maybe even micro-sized, amp and lightweight cab(s) with as close of an approximation of the ampeg sound as i can get --if that's remotely possible, hehe--i'm not really up on the current offerings...but i'd like a warm sound from the amp with my jazz basses--something not too different in character from what i have now i'd be using this mainly as something to carry along when i head across state to visit old friends for casual weekend jams...i've considered a DI box, but i don't always have a PA or powered speaker to run thru as i've had a recent herniated disc, i'm looking for light and small, so as not to have to wrestle bulky equipment from the car trunk any ideas?
If you're looking for a warm-sounding light/little cab that really rocks, I'd recommend the Euphonic Audio Wizzy 112. It's an efficient (102 dB) 4 ohm cab so it can put out quite a bit of sound with a small head. I power mine with a GK 400RB, and it gets very loud. Tone-wise it's right in between old-school and hifi--fat but detailed. Weighs 29 pounds, costs ~$500 new. A used Eden WT-400 or Mesa Walkabout head can be found used for under $600. To get that Ampeg kinda tone you might want to pick up a SansAmp Bass Driver DI. I have very good luck using a SansAmp to warm up the tone of my clean-sounding SWR Workingman's 12 combo. Also, the Ampeg B-50 (50 watts, 12" speaker, discontinued model) and B-100 (100 watts, 15", still made) really get a good fat vintage tone. The B-50 weighs about 50 #, the B-100 is a little over 60# but has casters. I think these amps sound a lot better than Ampeg's BA series combos.
Gallien Krueger MB150E. Light, old school, can get loud if it has too. Add their matching MB150 EX extension speaker--only weighs 11 pounds--and you have a 150-watt amp thru 2-12's with a total weight of about 35 pounds. These are also available used fairly frequently.
