PhotographyAnalog guitar multi effect processor
This was my first big project. An analog guitar multi effects processor. I built it in a time in my life when I had large amounts of spare time. I never got the equalizer to work perfectly, but the effects worked, and I still think it looks awesome. You can't imagine how long I worked on this thing! But, to be honest, it was worth it, because I played the hell out of it in my guitar days, and learned a lot about electronics. I remember very well working on the schematics when I was on vacation in France in 1995.
Front panel items:
- Power switch
- in
- out
- input gain
- distortion volume
- distortion gain and type (knob is lit depending on function)
- clean volume
- phaser speed (knob is lit when phaser is on)
- fuzz (a bit squeeky)
- harmonic enhancer (knob is lit when on)
- rectifier volume
- octave divider volume
- control buttons for phaser, harmonic enhancer and octave divider, disguised as depressable leds
- control leds for harmonic enhancer and octave divider
- VU meter
- 3-band EQ, cut/boost range very limited, a fault on my part
- master volume
It not hard to imagine I don't use it anymore. I have much better equipment now, and the thing is sitting somewhere, not even in working order, but I think I'll keep it around, just to look at it sometimes. A museum piece. Maybe some day I'll find the schematics (they're somewhere in a junk box in the attic), and put them up here, for everyone to laugh over. Including me
