This beauty is a late 90’s(96’/97′?) MIJ Jazzmaster. The big upgrades were already done in the form of a new set of Novak Pickups and a Mastery bridge! Still a few extra changes and a surprise repair were to be made. It had a 250K volume pot that we replaced for the original value of 1M(but Audio instead of Linear). The original tone cap of .033 had already been replaced with a .047 that we replaced with a Russian PIO .022. The owner complained about the rhythm circuit not being useful at all. It turned out the volume pot was broken and not working as it should. I had a small pot of the right value(but again, audio taper) that fit so we got it fixed. An last but not least, new TUSQ string trees as the string where catching on the old ones(yes, someone installed an extra string tree) causing tuning issues.

Guts!
