We are are pleased to offer our own custom branded and spec pots manufactured by CTS + a pair of Cornell Dubilier .022 Orange Drop Capacitors. These pots are identical in construction to CTS high quality 450G series pots, but we spec them at 525K. At 10% tolerance the value of these pots can range from 475K to 575K, and the majority of these pots will be much closer to the 525K spec. This means no exceptionally low or high resistance pots that can be found when using typical 20% tolerance 500K pots. Were very pleased with these pots and think you will be too! The only thing that might make these pots better is if they came with bacon. 525K Ohms/10% Tolerance (Value can range from 475K to 575K) Audio Taper Bakelite base plate Solid brass c-clip reinforced shaft Solid brass bushing 3/8-32 US thread 3/8" (short shaft) bushing height Split, fine 24-tooth knurled shaft 1/4" diameter shaft Each pot comes with hardware - nut, dress washer and lock washer Requires 3/8" diameter mounting hole Pot is maufactured and branded by CTS specifically for The Art Of Tone (TAOT), Part # 450S525KXL TAOT. Note: 1. If you are uncertain whether your guitar uses short (3/8") or long (3/4") shaft pots, as a general rule this pot will fit most USA-made Gibson Les Pauls manufactured before 1977, Gibson historic reissues, PRS and Hamer guitars, but please double check before you order. 2. Make sure to pinch the tip of the shaft before you try fitting a knob, this will avoid getting knobs stuck before you install the pot. If youve ever had that happen... 3. If you have an import guitar it is probably using metric sized components and these pots cannot be used without modifying the openings on your guitar.
