May i have a schematic/layout of the exact tone mods eh?  If it's not too much trouble....

i'm just curious how you gots all those tone stacks in there.... :icon_confused:



OK, I've checked my notes:
A tone stack consists of five parameters. I use the schematic noted in my first post as a reference. Two parameters I leave unaltered:
- 100K (RV2) pot to control the tone
- 22k (R17) to ground resistor (they were the same in both stacks)

I use a 3P4T switch to control the other three parameters:
- Position 1: Stock BMP: R18 = 39k; C11 = 3.9 nF; C12 = 10 nF
- Position 2: BMP + mid: R18 = 39k; C11 = 30 nF; C12 = 10 nF
- Position 3: Swollen Pickle stock: R18 = 33k; C11 = 3.3 nF; C12 = 47 nF
- Position 4: Swollen Pickle + mid: R18 = 33k; C11 = 100 nF; C12 = 47 nF

The swollen pickle tonestack (both stock as mid) are now my favourite; the tone knob is a bit weird: on the lowest setting the EQ is more treble than when the knob is turned a bit. The sound basses up a bit at that point.


Second, Processaurus , I will check out your options. Thanks!

Thanks, man!  Much obliged, i must try this.
