buzzy kustom [message #3692] Thu, 12 February 2004 20:38 Lucky Messages: 4 Registered: February 2004 Junior Member So awhile back I bought myself a sharp lookin' frankenstein head in black, a hundred watter that I've dated back to '66 thanks to instruction here about reading the stamped guts (no serial plate). I'm overall very happy with it, not only as a tough and bad-ass lookin' amp, but as pretty furniture as well. I'm constantly trolling eBay to fill my house with more tuck and roll goodness. My one problem, tho, is it has this low-level distortion...not in a good way, but as if something's dirtying up the signal and giving everything a metallic buzz. Is this a common issue? Something easily fixed, I hope? Report message to a moderator

The A's less than the B models but its really a hum. I don't have three prong cords on any of mine though. Report message to a moderator

Re: buzzy kustom [message #3706 is a reply to message #3700] Fri, 13 February 2004 09:24 Lucky Messages: 4 Registered: February 2004 Junior Member It's only when I'm playing thru it. Still got the two-pronger on it, but it's nothing like the standard ground hum issue. It sounds more like playing thru a really terribly cheesy distortion pedal that's only slightly turned on. If I'm playing bass in a band context thru it, everyone else's noise pretty much drowns out the distortion factor, but hearing it on it's own, or playing clean guitar thru it, the problem is obvious.

Senior Member It sounds like you have some crossover distortion. That is when the positive half of the signal crosses through zero and starts to go negative. If the biasing of the amp has changed over the years, it could show up at low volume. Once you start pushing the amp harder, the larger signal is a greater percentage than the distortion and you don't hear it. My brother, John, has a K150 combo that has that problem, but as of yet we have not scoped it to see the exact waveform. Conrad Report message to a moderator
