When your parents laugh at you when you say "I want to bring the combo amp" for an audition, it's time to get a new rig. I tried a peavey head and ampeg 2x10 at my rehersle space yesterday. It sounded very sweet. I really like the tone of Ampegs for cabinets, Punchy low mids, tight lows, clean, clear treble, but enough mids to cut through. I have a J-retro preamp, so I would like a pre-amp that won't color my tone entirely, as I would do all the EQing through the retro. I think I would be selling my Ampeg b3-158 to finance it. I bought it for $780 new 3 years ago. Any idea how much it would go for? $550?
