The first mod is the following:
- A piece of a 0,5 mm thick guitar cable (I take off the rubber insulation and put a shrink tubing in place), linking the jack to the pickups switch.
- I have Used two 22nF russian PIO capacitors at the begining, and then have changed one 22nF to 15nF to the rhythm pick-up (copying the popular woman tone mod).
- All wire used are non tinned copper thick wire.
- Implemented a 50's style wiring to increase the highs.
*The tone is warm and big, a lot of bass and low middle, good detailed highs.
- I guess, IMO, this tone is because the non tinned cooper thick wire and the PIO caps.
Using a 15nF PIO:
The second and current modification is as follows:
- All wires is a tinned copper wire (vintage style wire for guitar).
- Used two Russian capacitors PIO, one 22nF for treble and one 15nF to the rhythm (yes, the woman tone mod).
- The 50 's style wiring, to increase the highs, remains the same.
- Big potenciometers Gotoh 24 mm for a better construction.
*Sugestion: treble bleed mod (only the capacitor without the resistor option) for volume pots - 250pF to 680pF (sorry no pictures taken).
** The tone is dry, vintage, more single coil style, most of the bass and low middle are gone , highs became more extended and predominant.
- I think, IMO, this tone is because the tinned copper cable.
- Recently I have unpotted the pickups, seeking for a more detailed tone.
