I'm looking into finally getting a new rig soon, and I have around $600 to spend. I was thinking about getting the common Ashdown Mag 300H + Avatar B212 setup, but I went to guitar center and played through a GK Backline 600 and liked it a lot. I played it through the GK BLX-II cabs, 2x10 and then 4x10 since both are in my price range, and I liked the sound. Would getting the Ashdown+Avatar B212 be better than the GK setup? Does anyone here have that GK head or cabinet that can comment on it? Are there any other options in my price range that I should at? I'm looking for something versatile, but I mostly play blues/rock and would like a warm good-low-mids type sound (think Billy Cox/Jack Bruce).
