Hello,
Anybody know what changes Fender puts in the new Fender Pro Junior IV. It sounds different from the III schematic, but I don´t find any info about the components values for the new revision.


Best Regards.

Any help wil be wellcome  :guitar:

I don't have a schematic for you, but maybe the pictures in this thread can help you trace the circuit:
