Title: Foxx Foot Phaser
Post by: Arno van der Heijden on August 27, 2004, 10:26:07 AM
I got a little bit closer on my quest for information on the Foxx Foot Phaser (schematic anybody? :? ).
This ebay auction has some pictures of the insides of the pedal:

It is probably 4 or maybe 6 stages. OTA/fet-based?
What do you think?

llooks like a decent deal...
 I didn't see any LED/LDR arrangement, probably OTA based.
 I have a SS phazer in a VOX wah shell, speed controller on the treadle... 8)

I didn't buy it, but I always like to look at internals of fx pedals.  :D

Looking at the photo, my best guess is that it's a FET-based 6-stager.  You can spot 6 nearly identical transistor/resistor/cap clusters around what I gather are a pair of quad op-amps.

Maybe it's FET based (i.e. uses FETs as the variable resistance)?

edit: oops, that's what I get for staring at the picture for 9 minutes!
