    Gallien Krueger MB500 "Master" pot not working?

    Hello. I have purchased a used GK MB500 head, seems to be in excellent condition, but I have a control issue. When I turn the GIVE circuit OFF, the volume should be controlled by the "Master" pot, according to the original GK user manual. But the Master pot on my amp does absolutely nothing...

    Pairing Head and Cabinets

    I recently bought a GK MB500 head and was looking for a cab. The GK Neo 212 IV is what I have in mind but well, something came along and I grabbed it because... well....maybe I am impatient :), will I live to regret? A pretty good deal, I think, showed up for a DG 212NE so I snapped it, thanks...

    This amp head is in great condition, it does have one flaw the mute switch doesn't function properly. This is the reason for the low price. Everything else functions as it should and it will come with a footswitch and power cord. Price includes shipping in the Conus.

    GK MB210: Will it be enough?

    Hi, there All Ye Of Great Wisdom. I currently have a GK mb200 head which I run into a MBE 210 (1st gen. with the silver grille and neos @400 watts). I sometimes daisychain it to a generic old passive 15" PA-speaker to get full use of the 200 watts. I have even been running with the 15" alone. I...

    As said yesterday was a nice evening. Had the possibility to try some wonderful bass heads. At the end it was a tough choice. Let's say I didn't have any "personal favs". Every amp sounded great that's a thing that has to be said. I've tried them with the Mesa powerhouse 410 box, then (not...

    So my Gallien Krueger MB500 has (yet another) problem. Or if I'm to believe what I've read, it's a "feature" and not a problem, i.e. a safety shutdown due to overcurrent/bad cables etc... Scenario: I tried to use the MB500 with a cab belonging to a local venue's backline. The MB500 wouldn't...
