Title: carl martin plexitone
Post by: copachino on May 17, 2014, 08:19:25 PM

I built both, and the original plexitone sounds 100 times better
12 volts are felt
I posted the project on 1:1 plexitone freestompboxes

Did ypu make the layout???

No,
I used the layout from a brazilian forum,
this one: https://www.dropbox.com/s/sh5w1pyd5ia6ujx/PlexiDrive%20-%20Big%20Louis.pdf?dl=0 (https://www.dropbox.com/s/sh5w1pyd5ia6ujx/PlexiDrive%20-%20Big%20Louis.pdf?dl=0)

the name is plexidrive, but the schematic is the same as the Plexituna, with only one gain Pot.

I'm thinking of using a switch to add a 110k resistor in paralel with the 1M pot to have crunch and hi gain with the same pot.

but at lower gain settings it becomes as crunchy as with the 100k pot.
