DMS-1 - mustang/duo-sonic short scale

Ps: is that a new photo of you there?

It is indeed.

As long as it's a very small drop of super glue. Loctite would have been a better choice

Agree but i was being lazy....

Now that we have settled into our new place i can kick off Phase 2 of this build
500k pots. New knobs. Hot rail type humbuckers.
But i cant remember the cap that should go with this setup. Doh!

Leftovers from past disasters

You've got two linear pots (B500) there. You'll need at least one A500 log pot for volume use. I prefer to use log for tone as well, though as I don't use the tone control, linear is also fine for me.

All your caps there look to be 0.047uF caps, whereas you'd normally use 0.022uF caps with humbuckers. I try and use 0.01uF caps these days as for me they give more control over a wider range of useable tones, but you don't get a real mud option (if that's your thing).

With the tone control right up, it really won't make any audible difference, but the tone will loose a lot of top very quickly with 0.047uFs and humbuckers. Slightly brighter than normal humbuckers, but still humbuckers with higher inductance than single coils so a lower resonant frequency.

Hi Simon-
on the point of pots. I thought that the B pots delivered a consistant change through out the sweep and the A pots were mostly in a quarter of the sweep. thats why i chose the B pots. am i wrong there?

on the point of caps. yeah. my eyes are so bad I had to take a photo of each cap and enlarge it to read the words! now ive got to find a 0.022uF somewhere in my collection - or head out and risk the covid nightmare at at the shops - he he he

Im also going to put a trebble bleed on this guitar. any ideas on a combo of options?

Like everything in guitar tone, personal preference rules. The same applies to treble bleed circuit values.
There are nearly as many combinations as there are values. It's often a process of trial and error.
Also different pickup manufacturers have combinations that they favour and presumably work best with their brand of pickup.

I'll attach two items that may help you sort this out. One is just a simple diagram showing three basic methods, the second is a list compiled by an online acquaintance of mine that shows cap & resistor values by pickup maker/brand.

FWIW, the past few years I've been going with the "cap only" method. This works for me, but YMMV.
I use a .001uf cap (code 102).

It depends whether you are talking about resistance or about the audio results. B/linear pots give you a linear change in resistance throughout the sweep, whilst A/log/audio pots do have the resistance change all bunched up at one end.

But our ears don't hear volumes in a linear manner, but a logarithmic one. We have a very wide dynamic range of hearing, and can hear very, very quiet sounds indeed, all the way up to extremely loud ones. If our hearing was linear, the louder sounds would simply swamp (what are to us) slightly quieter ones, so that talking in a (pre-Covid) restaurant would be almost impossible.

So the change in resistance needs to be logarithmic too, to match the way we hear. Only then do we get a change in volume that appears linear to our hearing.

Gold.
Now i get it.
Thanks Simon

Wow.
That DrKev is really good!!!
His analysis and notes are quite objective.
I got a lot out of that. Thanks heaps McCreed.
