#4 & 7 have been sold....... Each board has been gone through, the transistors have been replaced with 1960s Vox wah correct Hfe, transistors used are a
BC109B found in the 1967/68 Vox Clyde McCoy's, the other transistors is a suggested replacement transistor for the 1969 vox 846 wahs, of the two there is no "better transistor" both are good, both will deliver great tones.
if you look at the very last picture you'll see most all these modern boards had transistors with an Hfe/gain of 800ish,
this is insanely out of spec from the originals & leads me to believe nobody checks these part for correct values. their just thrown together
all boards now have the correct 1960s Hfe, the boards now have a quality Polystyrene cap, Correct value.
Last you'll see the caps have been pulled & replaced with vintage 1960s made in Holland trop fish caps.... The transistor change alone should give your wah a change for the good.
I left the stock inductors, Its my belief after thousands of wah builds if you were to take what you believe to be your best inductor that has the same value as these stock inductors your gonna be hard pressed to hear a difference if any at all at volume. in my opinion the inductors don't play the role their hyped up to play & offer a very subtle change.
Pick your board while they last! 1 to 7. plug & play!
they'll ship USPS 1st class with tracking
