offboard wiring for pnp sunlion type pedal

[pete74]

Hi.  Hoping someone can point me to an accurate offboard wiring diagram for a combo fuzz face & rangemaster type pedal.  Both circuit's are built with PNP transistors like an analogman sunlion.    Or, would this be as simple as combining the power & jacks as in two individual pedals?

FWIW I'm only planning to use a battery for a power source.

thanks in advance

Are you planing on having a switch for each circuit or one running straight into the other bypassed by a single switch?
If your running it off batteries i can't see it being too complicated, it's not like you're trying to daisy chain in to centre negative pedals.

Yes, a switch for each circuit.   So either one can be on or off individually.

Build a 555 voltage inverter for the sunface and build the negative ground rangemaster.  There's a schematic for a PNP with negative ground.  Good stuff

Surely easier just to flip the battery?



Notice the terminals on the battery are reversed in this image so ignore conventional 'red is 9v, black is ground' colour scheme.  Also you'll need to flip the polarity of those LEDs or they won't work. Other than than i can't see why it wouldn't work. Maybe there's something i'm missing here that somebody can point out?

If you swap the trannies to NPN and flip the electros it will work negative ground.. but I'm not sure if my man here has decent NPNs for a fuzz face variant.  That's why I usually use an inverter myself, just recently I got a pile of 404B's that fit the bill

Thanks very much!  This eventually worked out for me!
