I've started to really like how Ampegs sound. Does this Ampeg sound come mostly from the pre-amp/head or the cabinets? I played an Ampeg SVP-Pro (with some other random power amp) in an Ampeg 210 today. If I used the SVP-Pro with say, Avatar cabinets, would I get a similar tone? What if I used the Ampeg cabs with other pre-amps-- would there still be any of the Ampeg "color" to the sound? Also, are there any other brands that have a similar (not identical, obviously) tone to Ampeg? I want to know for comparison shopping.
