    So I've had to completely rewire my Streamliner, the wire had deteriorated and there was no saving it. My question is, why did they use this double pot in the tone circuit? Its not working and i need to replace it, I'm thinking a single pot should suffice. 20190707_091844.jpg

    Can't see the connections but I can see two caps. So I suspect that it's wired so that one is increasing while the other is decreasing.

    The Streamliner only has one pickup.

    Yes. The Gretsch dual tone pot much like the TBX is treble cut one way, bass cut the other.

    I found the same pot configuration on my buddies '56 Silver Jet. I searched for a couple of weeks and never was able to find the 550K/250K combo in a double pot. The pots were shot, so I was never able to hear what a difference it made, so ultimately I just wired it for a 500K and called it good. It worked fine and sounded great, and my friend is never going to sell the guitar, so he didn't care about keeping it original, just wanted it functional. The biggest problem I had was the wiring was so old it just kept cracking and shorting every time I moved the harness. I eventually had to nearly rewire the whole thing with new shielded wire.

    If you do find that pot combo, I'd love to know where...even though my buddy didn't care, I still want to rewire that guitar correctly!

    Premier guitar magazine has an excellent modding column by Dirk Wacker.
    He did a two part feature on modding the TBX. It’s worth checking out. He basicly said it was pointless looking for a diy stacked or stereo pot solution. Fender has these pots custom made.

    That's exactly how these wires were, i replaced them all including the wire to the DeArmond......it ain't original if it don't work! I will keep looking for the pot, and i may try to take this one apart and fix it.

    Yes the tone pot is double cut with a std treble cut cap but also a bass cut on the other. So it should be on the middle to be close to the neutral position.

    This is a great tone shaping solution, I love them with Dearmonds.
    The counterpart of the versatility is that they're sucking a lot of volume, that's why they came with 1MOhms pots (at least on master volume) to compensate the loss for the tone stacked pot (I saw later 57 models with 1MOhms as MV but 2 x 500K for individual volumes, and this combinaison was even better to my ears).

    I will tell you a secret if you tell nobody, bypassing tonestack will give you a kind of built-in booster with at least 25% more volume. A little mod for men but a giant step for mankind : look the miniswitch under the pickguard !
