To make a long story short the fx loop on my GK Backline 600 crapped out, sent it to the shop, $275 was the estimate, I guess there was more problems than I though (its a very reputable amp tech that I know would not rip me off) so Im in the market for a new or used amp. I had a GK1001rb and loved it, the Backline 600 suited my needs very well so Im unsure if I should just stick with GK or turn the chapter to a new amp company. The Hartke LH1000 sure does look appealing but can I get the famous GK growl out of the Hartke. Should I get new or used. Any suggestions would be appreciated. Sorry for rambling on, I just got the call from my amp tech and you guys are my go-to people. Money isnt really an issue but I would rather spend less than more.
