Hi to all GK owners out there...in particular owners of the GK 1001RB II. I'm curious to know a bit more about the ins and outs of this head. I've read through the reviews and out of them, the main problem anyone had with it was the plastic inputs and lack of compressor. I'm curious about how "bright" and "attacking" these amps are (if that makes sense)? I know they're renowned for their bright, punchy tone and was wondering how they go with an active bass for example (I'm playing a warwick thumb). Also, how loud do these really crank before you start pushing it too far? Is there a lot of headroom in this amp to allow for keeping the clarity as you crank it up to keep up with a loud drummer and guitarist? I'm playing heavy progressive rock style music so I'm looking for clarity across the whole bass from open Ds (dropped D tuning) to high up on the G string. The biggest problem I've found with previous Amps and tube amps in particular is the lack of clarity as you push the volume up and start trying to play more intricate stuff with effects on where you really need that tonal clarity as opposed to the "tubey wamth" that everyone raves about.
