Besides the AF2, that 535 wah is probably the best gear investment I ever made.
Love it!
These are my two "babies"...
The older one on the left is just magic. But dirty and noisy.
I believe these are both from the 70's. Possibly 60's for the one on the left.
I use my wah for very slow synth-like filter sweeps most of the time. Great with viola!
Clip … or it obviously did not ever happen!
