This looks awesome. Did you use a 2N3906 instead of BC307B? It said 1N3906 and I can't find that but I have 2N3906's. Sorry I'm not the brightest tool in the shed.

You can use a SPDT ON/OFF/ON for the Shift Toggle instead of ON/ON & add a 10 or 15nF capacitor to give you an in between shift so you have 3 instead of 2 positions!
It requires just soldering the cap between bottom Toggle pad & Leg 1 of Tone pot like I did
Mine is on the Solder side of the PCB :

What? No Eyelet Board? ;)
Well done as always, Phill. The FAT switch & 3-way shift are cool & easy mods. That Fat cap could be even fatter, I went with 47nF on mine.
