I have a strat style guitar. I made myself a p90 pickguard. I have a stacked wilkinson p90 for the bridge (14k splittable) and a p90 single coil for the neck. This config will suit me as I like single coil chime on the neck and higher gain on the bridge. I also use a treble booster model on my line 6 but sometimes the added treble makes the bridge sound shrill. I will use a 3 position switch but I'm lost on pot values and cap values... what should I use? At most I will use 1 vol 1 tone.

I'd suggest 500k log pots for both, with a treble bleed circuit on the volume pot (150k and 1nF in parallel). that will keep the B pickup sounding clear, and you can always turn the tone down if needed.

Sounds great but I don't have those bits on me... I will order those if i do like the overall p90/ strat config. I have found 2 500k pots although the tone is a 500k linear with an orange drop .22 is that a close 2nd?
I have also found 2x1 meg pots and a 250k blend control... I like the idea of a blend control but 250k darkens things up?

PL- Welcome Back! Should be fine. It will, but consider that, if used in conjunction with another 500K pot, the overall resistance will be 167K. If used with a 1M pot, the total resistance is 200K. There may not be an audible difference between 166K and 200K. If you used the 2 500Ks originally discussed, you're at 250K. I suspect this would be discernibly different from 166K. The 2 1M pots together gives you 500K. That would likely be quite bright, perhaps even the dreaded "icepick-y". Now, that's for 2 pots. If the blend is to be used in addition to the V and T for 3 pots total, the numbers go down accordingly, meaning it will get a bit darker if you go with 3 pots. If it's 2 500K pots plus a 250K blend, you're at 125K; using the 2 1M pots plus the 250K blend puts you at 167K. Again, a difference of 37K may not be audible, but I've never tried to do an A/B comparison on this stuff so who knows? Keep in mind the basic rule, though- it's easier to take brightness out than to add it. If it's too bright, you can (heaven forbid!) back off on the tone control. If it's dark to begin with, it'll stay dark . . . If the blend control is the type with a center detent, measure the resistance at that detent. Then read this: Blend and Pan Pots
