I'm thinking about selling my GK 1001RB-II. It's served me pretty well over the few years I've had it. It's never been gigged, unless you count a couple coffee shop sessions. Most of its 3 years with me has been spent as you see it in the photo -- just sitting in my bedroom. The volume's never been past 3. No serious problems since I've had it, except for one thing: There's a speaker pop when I turn the amp off. The pop isn't there if I turn the volume down before powering down. Aside from that, it sounds and plays flawlessly, just as it should. You just have to turn the volume down before turning it off.
I recently took it to Tim Gibbs, of Toy Box Audio, a certified GK tech to figure out the pop, but after 6 months (took it to him in March, got it back in September) and $212.50 worth of time and labor, he couldn't find anything. He removed the preamp board, cleaned the pots, looked up ECOs, called GK twice, and replaced two transistors. In the end, though, the amp still makes a pop when turned off, UNLESS I turn the master volume all the way down. With that in mind, Tim said he was pretty sure the problem is in the preamp board and could only suggest, at this point, that I ship it off to GK, who will likely just replace that board.
Asking $400 shipped, or shoot me amp trade offers.
I need something lightweight, and I'd like to try something with a tube.
Here are some I've been eyeing:
- Carvin BX500
- Genz Benz GBE-600
- GK 700RB-II
- GK MB2-500
- MarkBass LMII
