I replaced the pots in my spalted TSB AL2000 to CTS pots a few months ago. Fine initially, but then developed a hum. Checked grounds and reflowed a few that looked like they could be the culprit. Still had hum. Put it away and got busy with other guitars for a while, so it stayed in the case. Got it out again a few days ago, determined to get it straightened out. Again checked the grounds, all seemed fine. Removed the jack, connections looked fine. I did notice that the lugs on the jack seemed to be touching the inside of the hole when I pulled it out. There is some of the shielding paint inside that hole. Bent the lugs a bit so they didn't touch the inside of the hole. Plugged it in and the hum was gone. To be on the safe side I did wrap electrical tape around the jack before screwing it back in place. Is it really possible that could have been the cause of the hum? Been playing for over 60 years and never encountered this before. Anyway, since then I have been playing it a lot and am again really impressed with this guitar. I did put a set of Giovanni GVH-1's in it a couple years ago. Just plays, feels, and sounds great. I have a hard time trying to figure how the upper model ALs could have been much better and what there was to be gained. I know they have ebony fretboards, but I am fine with the rosewood. More bling (binding on the headstock) isn't a big deal to me. I prefer the plainer look. I change pickups in nearly all my guitars, so what else would there be to be gained? Considering I bought this new from Rondo on sale for $179 (not a b-stock) it seems like the best deal I ever got on on new really nice guitar. My only regret is that I didn't buy at least one more before they beccame discontinued.
