Hello, I've been looking at options for a power amp for my Ampeg SVP preamp. I have heard some guitar players rave about the matrix amps with processors like Axe FX or POD HD, but I haven't seen much about it's use with bass and using a more traditional preamp for the front end. I also have a few Tech 21 units (RPM and RBI) laying around. These might also make a good front end. I would certainly not mind carrying it around in a 2 space rack. Here is a link to the amp. http://usa.matrixamplification.com/rack-amplifers/gt-1000-fx-1u.html For cabinets I'm using 2 Eden 4x10XLTs. Any thoughts or experience would be helpful.
