I've removed my tone pot, JM screams

Post by aleshka » Thu Aug 28, 2014 9:43 am

I've got 1994 JM66 japan Jazzmaster with Antiquity II.

Recently I bypassed my rhythm circuit and removed tone pot, leaving only 1meg volume knob. I might be a bit crazy, but it seems like my JM screams now and the sound has lost something warm, though gained a lot of clarity.

So the question is how many of JM users do that and what pot resistance should be used to have the most interesting sound?

I am very interested in this topic as well.

By "screams" do you mean insanely bright and shrilly? I'd imagine with a 1meg pot that would be the case?

I would like to do something similar but I'm looking to retain a sound close to a normal circuit without all the extra knobs I don't use.

I generaly remove all tone pots in every guitar I get.I see no point in them(for my use).My VM Jazzy has been tone pot-less since a week after I got it.I believe it may add some brightness/clarity but if it does it's minimal,not earth shatteringly different imo.

Are you swapping out the stock electronics? Or just simply removing the tone pot? I'm wondering if higher quality CTS pots would make a bigger jump towards brightness.

In the Jazzy I gutted everything.It has:neck pickup,bridge pickup,3way toggle,500k CTS pot(vol)and the output jack.I swapped in the CTS only because I had no Alpha 500k's around.To the best of my knowledge(limited at best lol)there is no difference tone wise between CTS&Alpha pots.I could be very wrong so if someone more knowledgeable wants to chime in it could be helpfull.

I've used 500K and 250K, depending on the particular guitar and pickups.

A single 500K volume pot will get you back to where you were with the original setup.

Any chance you have a schematic for such a setup? I'd like to try this out on my guitars. It'd be nicer and more dependable than having tape everywhere.

Sorry I have neither the computer skills or drawing skills to make a diagram of this type of setup.I'm almost positive that the Seymour Duncan website Wiring Diagram section will have a similar diagram available.

That's pretty much the Thurston Moore signature model right there. Antiquity II's, no other pots but a 500k volume. I wouldn't say mine screams. It seems to be as clear as my other Jazzmasters, no more treble than normal. That guitar is a little more forward, a tad hotter and bolder, but that could be the pickups.

Are you sure it' 500k? I always thought Thurston uses 1meg pot
