Hello everyone! I recently bought a used Hartke HA 7000 (2 channels, 350 watts each channel) off of Ebay with a rack bag for $405 (in mint condtion)! Anyway, the price was right, but what is the overall opinion/s of this head unit? I know that is has enough power for most situations, but what about tone, adjustability, reliabilty, etc? Thanks much in advance!
