Help revive my old Sola Sound Auto Wah

[reverberation66]

nice job of removing the "meat axe", who would do that?? awesome that you got it working again, I just revived an old MXR distortion + that I've had forever.  The wiring was all messed up and it had black goo all over the circuit board but I got it working and it sounds great!   thanks for the schematics jimi.  So would the LM3900 have the same pinout configuration as the original chip?

cool, thanks...yah, not the most exciting auto wah... but still i bet it would be useful if messed with right...

the big thing is guitar knob volume and pick attack...or does it just sweep like that no matter how you set it?

still may be a fun one to breadboard, at least...thanks mwinwood!

looks like it could be fun to mess with!
