@ dingobass Pretty cool bass amp there, heard lots of good things about Hartke amps, I have a Bass amp but it's only an old 80's Peavey TKO 80 (the one without the graphic EQ).
Bass amps need to be pretty substantial since the human ear isn't as sensitive to bass frequencies as it is to midrange frequencies, hence the reason why you see a lot of 500W and 1000W Bass amps.
Wouldn't mind owning a good Ampeg SVT rig though.
