the larger the pots value , the brighter the sound. But it has limits..you can't simply install 2M or 3M pot.. for safer way, always follow the recommendation from the manufacturer. When you buy a pickup, there is usually a recommendation about pot and the installation/soldering guide in the manual.
What pickup model do u use? kalau SD atau DMarzio, kat website dia ada guide..

Kalo aku,
if guitar aku HSS = lebih banyak single coil confugiration maka aku akan pilih 250K utk volume pot. Humbuker bridge biasanya moderate tak hot sangat supaya balance dengan single coil.
tapi utk guitar HH jer sure akan pakai 500k utk volume pot.
Tapi utk tone pot, nak pakai 1 meg pot pun tak per, jangan risau tak semestinya volome pot pakai 500k the tone pun nak pakai 500k juga. Even stat yang pakai 250k pot volume biasa kita dengar pakai 1 meg tone pot.
Tapi kalo nak pakai multi wiring design macam spli, phase, parellel, di syorkan boleh carik pot push n pull knob, ari tu angkat yang murah jer dalam rm25 kat woh fatt, yang ok dalam ranga 40 ker 60 cam tu.
tapi aku sekarang bersetuju letak satu resistor 300k dan satu cap 560pF kat parellel dengan kaki 1 dan 2 pot [hot leg]. lebih smooth skit, treble ada macam mantain skit. Terutamanya geng geng yang suka pakai pot murah macam aku... hahhahahaah.

Selecting the Right Potentiometer
Guitarists are notorious for their "do-it-yourself" attitude towards instrument maintenance and customization. Most of us won't hesitate to take our guitar apart at the first opportunity if it means avoiding prohibitive bench fees at the local repair shop. There are definitely conditions that call for professional intervention, but with a little bit of knowledge there's no reason that many of us can't handle some of the simpler tasks involved in maintaining, repairing, and customizing our guitars.
Replacing guitar electronics is a fairly straightforward task that can be successfully handled with minimal effort. All you really need are some basic soldering skills and you're ready to go. Most conventional guitar circuits consist of pickups, switches, pots, capacitors and a jack. The hardest part is determining what value of potentiometer you need for your instrument. With that in mind, let's take a look at some of the determining factors that will help you make an informed decision when it comes time to replace a volume or tone pot.
Basic rule of thumb goes like this: single coil pickups get a 250k pot, humbuckers get a 500k pot. Why is this? The higher the value of the pot, the brighter the sound, so higher value pots are used with humbuckers to allow a bit more high end to get through with what is, by design, a warmer sounding pickup. Lower value pots are used with brighter sounding pickups to tame some of the extended high end that is associated with single coils.
The Effect Of Potentiometer Values In Relation To Output And Tone:
As a potentiometer is turned fully down, all of the signal from the pickup(s) is diverted to ground, resulting in no output from the instrument. When the potentiometer is turned up to full volume, the resistance of the potentiometer theoretically prevents any of the output signal leaking to ground, and weakening the output signal. Lower value pots, however, do not completely block the signal from leaking to ground even when turned up all the way, so using a 250k potentiometer will result in a slight loss of high frequency, as well as volume. This may please some musicians who want a mellower tone, but for those seeking ultimate purity of signal, a higher value potentiometer may be just what is needed. The higher the value, the more leakage is blocked from ground, which allows more of the signal to be sent to the output. A 500k pot may be just right, but a 1meg ohm pot will provide an all out sonic assault. Higher highs; lower lows; more volume - a rocker's dream! The only drawback of going to this higher value is the perceived range and sweep of the control. It's like going from 0 to 10 without the fine increments of control in between.
The Telecaster® is a good example of potentiometers determining the overall sound of an electric instrument. The earliest Telecasters® utilized 1meg ohm potentiometers. They were deemed too bright to be practical for a wide range of musical styles. As a result, the potentiometers were changed to 250k to "bleed off" some of the extreme treble "twang" that the early versions were known and loved for (Stratocasters® also use 250k pots for the same reason). Some Gibson® laptop guitars had 5 meg ohm pots. Talk about bright!
Exploring Your Options...
To find out if switching to a higher value pot might benefit you, try this simple test: Disconnect your pickup(s) from the circuit, and use some "jumper" wires to connect them directly to the output jack. If the pickups sound louder and fuller, then you will benefit from a higher value potentiometer. If, however, your pickups still aren't sounding the way you'd like them to, maybe you should take a look at our Kent Armstrong replacement pickups!
Hopefully, this guide explains why certain value pots are used with certain pickups, and arms you with the knowledge necessary to experiment with some non-traditional alternatives. For replacement pots, check out our Guitar Electronics section. There you will find top quality replacement pots from CGE and CTS (as used by Fender since the early 60s').
