I need some specific advice on what to buy here. I'm thinking I'm going to go with Fralin P92s in my AS80 and I want to have the tech switch out everything else while he's at it...switches, capasitors, caps...??? I'll most likely get everything at Guitar Jones, so just tell me what to buy and I'll take it to my tech.
You guys rock. |

Volume pots: 250k ohm is the standard for single coils, while 500k ohms is what one normally uses on humbuckers. Some people have reported good results with 1m ohm (1 mega ohm = 1 million ohms) used with P90 single coils. Since you like bright sounds, I'd go with 1meg, tapered. (tapered is another way of saying log, or logarithmic).
Perhaps someone else can advise you on the tone pot and cap. Tone pots are normally linear, which means that the impedance changes a constant amount per degree of rotation.
I found the following info that may offer some guidance:
• How does the tone capacitor value affect tone?
The most common value capacitors for guitar circuits are .022 uf and .047 uf (where uf is the symbol for microfarads, sometimes referred as MFD). The tone pot and capacitor are wired together to form what is called a variable low pass filter. This means as you dial in the tone pot only the low frequencies pass to the output jack and the high frequencies are grounded out. The selected capacitor value will determine the "cutoff frequency" of the filter. Larger capacitors (eg. .047 uf) will have lower cutoff frequency and sound darker when dialed in because a wider range of frequencies is being reduced. Smaller capacitors (eg. .022 uf) will have a higher cutoff frequency and sound brighter when dialed in because only the high frequencies are cut. The convention is for humbucker equipped guitars to use .022 uf capacitors and single coil equipped guitars typically use ..047 uf capacitors. However, feel free to experiment. Some like to use .033 uf capacitors since they are in between .022 and .047. |
