So many vintage guitars in the past have been “upgraded” with Schaller, Grover or Sperzel type tuners. While these tuners are a better quality component they do not look like the originals taking away form the factory vintage look and they actually change the response of your guitar by adding more mass to the headstock. The difference is subjective because every player is different. By installing these upgraded tuners the guitars headstock has to be drilled to accept the larger bushings. Original vintage type Kluson tuners use an 11/32″ hole while the upgrade tuners use a 10mm hole. If you want to return the guitar to it’s original state the Kluson bushings are too small for the 10mm hole and fit very sloppily at best. This sloppy fit can cause all kinds of tuning problems and cosmetic damage to the headstock from the bushing leaning and digging into the wood. The common repair is to dowel the tuner holes and re-drill them. A skilled tech can do it but without the proper tools you may have a nightmare on your hands trying to drill the dowels perfectly centered and perpindicular to the headstock. There is an easy repair for this without using any dowels, glue or a drill. Allparts makes an oversized bushing called an “adaptor bushing” that will fit into the 10mm hole perfectly but has the inside diameter for a vintage type Kluson tuner shaft. Outwardly the adaptor bushing looks the same as an original. This is an easy way to restore your guitar to it’s original look and vintage performance.

David Nicholas - The 20watt amp is sounding fantastic! Delivered the goods at the gig and I'm finding cool tones all over the place with it. Love the cab w Emenince Tonkerlites too- perfect for my sounds! Makes the 12 string sound like a grand piano!
Peter Lacis - I had an audition for something recently that was all about Led Zeppelin I -- my custom Pennalizer BLEW THE MINDS of the guys I was playing with. They couldn't believe the sounds coming out of that amp. That album was never in my mind when I came up with the that's yet another testament to the amazing work that you do.
Scott Goldberg - I am very satisfied with the set-up, and the fast turn around.  With the "lower" action it feels easier to play.  I will definitely spread the word.
