since the Fender skirted knobs do not really match up with the others, I try my luck here. Does anyone perhaps has some leftovers (maybe from a broken Amp) or knows were one can get them?
Probably the only place that you will be able to get those knobs from are from another Kustom amp. I have not seen them used on any other brand of amp or in any parts catalogs that I have looked at.
The knobs that we have discussed here before are the ones used on the older tuck and roll models.
You could just replace all of the knobs to make them all match.
At least your answer tells me that I can save time and stop searching for them any longer. I guess, if you not have seen them anywere else, I can be sure, that I won't find them either (sitting in Europe).
Replacing all, to have them match each other will be my last resort. I will keep on searching for a defective Amp on Ebay now. Unfortunately these are rare here, the tuck 'n' roll models seem way more common (among the contemporary china build ones of course). Actually a shame.
I do not understand, why these Amps weren't sold more in the days and other designs are used by the Chinese. I love that I am able to get a really warm sound on that Amp and on the other hand I am able to create a nice old style funk sound, too.
By the time that that amp came out Kustom had been sold a few times and were carried by fewer dealers. Plus there was a strong bias for tube amps and vintage amps here in the U.S. and generally solid state was a little less popular, at least for a little while.
