I love(d) my GK 700RB 2x10 combo amp. It mixed perfectly with my Peavey Cirrus but now that I have purchased a Warwick Corvette 5-string the tone (or ability to handle the heavy lows) went to crap. I love the heavy growly tone of the Warwick but I don't really want to buy an Ampeg to do the bass justice. Overall, the tone with the GK and Warwick isn't bad, it just seems like the GK can't handle the low notes and thick tone, it's overloaded. I'm looking to beef up my amp setup without spending a lot. Does anyone have a suggestion for some 10" speaker upgrades or another speaker box combo that would work out good? BTW this amp is 8 years old and has seen a lot of use. I used to leave it in my car a lot too with speakers facing upward. Is anyone using a Warwick with a GK combo amp? Thoughts? Thanks greatly for any input.
