I've had an AVRI Jazzmaster for several years. It was never one of my most-played guitars for a variety of reasons, but mostly because of the shrill ice-picky high end that i heard through every single amp I played on. I decided I wanted some Antiquity II's, but needed to let the initial blow of spending the money on a fairly high end guitar wear off before spending MORE money on it. It took a back seat for a long time.
I'm a huge huge Danelectro fan (90s reissues rule, haters.) and decided I wanted to take a page from the book of danelectro and make a wooden bridge for the Jazzmaster. So I did! I used a scrap of mahogany (WAY too soft.) to make 6 new bridge saddles as a test. It's alright, I'd like to use rosewood and construct it out of one compensated slab and make a new bridge baseplate for it to attach to... but whatever. My point with this exercise was to tame the ice-picky high end. It really didn't work; more than anything, it just changed the attack and sustain properties, but not so much the tone itself. So I dug a little further.
Why the hell does the brightest guitar in the world (well, second brightest to the Jag) use 1 Meg pots?! I'm not an electronics pro by any means, but I know that higher value pots let more treble through. So I decided to swap them out for some CTS 250ks I had laying around. After some struggles getting thigns to fit back in without grounding out on the shielding, it works! But...
I don't notice a huge difference between 1 megs and 250k's!! I'm completely shocked. The rhythm circuit still sounds more dull and subdued (is that a 50k tone pot?) which is surprising to me. I expected a HUGE night and day difference when knocking those pots down to 1/4 of their previous value, but if anything, it only touched the ice-picky peaks, and i'm not even sure if those are gone as I haven't gotten to play this at higher volumes yet.
Should I have noticed more of a difference, or does this seem about right? Also, the fact that the rhythm circuit is still a 1meg (i think) along with that 50k makes me wonder, which pot's value affects overall tone? What difference would I hear if I had left the 1meg volume in, or the 1meg tone in, while replacing the other with a 250? I know I could try it and find out, but it's a hassle and you guys might just tell me 😀
