Hi All,

I'm drawing up my wiring diagram (very crude! Must apologise, I only have MS Paint to work with) for my home-built Strat-project. I am using Star Grounding and have shielded the cavity and pickguard/Scratchplate.

The wiring I am trying to achieve is a hybrid of the Spin-a-split mod and a Master Tone Mod. The guitar has two Texas Specials and a Jb Jr. One tone will be the Spin-a-Split, the other will be a Master tone, and the third pot a Master volume. I've not seen anyone do this, so i'm quite excited about the potential results.

My schematic, so far, is pictured below. The pot values are what they are purely becasue that it what I have. I hope these will be OK. Any recommendations much appreciated. My schematic stops short of the Master Tone, and i am hoping someone might be able to

1) Check my wiring is going to work, before I wire it this way and
2) Suggest how this schematic can be modified to use the remaining tone-control as a master tone.

Thanks!!
This should do it:
Artie

btw - That gives you the 50's mod. Connect that greenish-brown wire to the red of the volume pot for a quot;normalquot; tone control.

Artie, I knew you'd be first to reply. Thank you so much!

Artie drew it with the tone control attached to the middle terminal (the output) of the volume pot. The second way to do it is to attach the tone control to the terminal with the red wire on it: the input. The second way is actually the standard way of doing it and will result in a slightly warmer tone. I do it the way Artie drew it though...that's called the quot;50's modquot; when it's applied to a Les Paul and it'll result in a slightly brighter tone and will retain highs better when you reduce the volume of the volume pot. Lew

Lew . . . you've converted me.

The 50's mod is quot;normalquot; for me now.

Thanks Artie! Your alnico 4 magnet went out this morning, BTW. You should have it by Saturday. Enjoy! Lew

Thanks Lew. I'm chompin' at the bit, since John's A4/59 thread.

Like this?

Sorry for taking so long to get back. Your last drawing is wrong. You don't want to change anything on the volume control itself. Look at the diagram that I posted. The only thing you'ld change, is to move that greenish wire that comes from the tone pot, and move it to the lug on the volume control that has the red wire.

Also, you don't need that extra connection that you make on the 5-way. That connection does nothing.

Artie

Splendid!!! Thank you Artie and Lew. I'm good to go now that I understand. quot;Warmerquot; sounds good, so I think I'll do the 'normal' tone first and if it's too muddy, I'll go for the 50's mod.

Incidently, what do you guys think of the pot values? What would be the effect of changing these between 500 and 250?

Your help really is appreciated.
I actually have a 0.047 orange drop cap for the master tone. Will this be OK over the 0.22?

I completed the wiring today, just need to put the neck and strings on!

OK, so I wired this baby up today (but moved the greenish brown wire to the other lug of the volume as suggested. All positions work just fine. Thanks to you for the assistance and confirmation that the schematic was correct.

One thing though. When I turn the Master tone down, it really doesn't roll off any frequencies untill it gets right down to 0 when it very abruptdly rolls off all the treble. Not very linear at all. It's a 250k CTS pot that came with another 250k and a 500k pot in a Fender pack (with the 0.047 orange capacitor and wire etc).

So did I get a linear pot when I needed a sweeping type? Am I using the wrong capacitor value? Or is this 'the norm'

Cheers!

Can anyone that got it repost Artie's diagram? Somehow I can't get it as is-

Thx!

This was basically Artie's redraw, except I've moved the green/brown wire from the Master Tone, to the other terminal on the Volume pot. As suggested for a 'warmer sound'. I have wired my guitar exactly like this, except my capacitor is 0.047 not 0.022 as suggested by Artietoo.

I should mention too that the position 2 and 4 on this guitar sound really weak and mettalic. Think somethings gone wrong there
