Maestro Fuzz Phazzer FP2-3 - modified

 

This one belongs to the category " old, weird and forgotten". Maestro Fuzz Phazzer was an odd piece of gear, a gnarly fuzz based on Maestro FZ-1S Super fuzz followed by an optical discrete phaser circuit....without a LFO. The sweep was controlled by a foot treadle which also acted as a volume control in "bypass" mode.

I had to do some modernizations for this. First, true bypass. Second, get rid of that  dual gang 30k phase/volume potentiometer. I replaced it with a single 50k pot so you can use either a normal wah pot or a normal potentiometer. The volume function is lost but I added a master volume control at the end of the circuit.

There are some things that need to be tested as well; the LDRs and the mini lamp. I can't find any info on the stock parts but a good start might be socket some Univibe LDRs and a random mini lamp with solder leads.

    1. Thank you.

      Yes, I have heard of the FP-1 but I've only seen a schematic from a Maestro service manual and these usually have all kinds of errors so I simply skipped that one. But with the project files you linked to, it will definitley have a layout...sooner or later.:-p

  2. Nice work! I definitely prefer the sound samples I've heard of the FP-2 over the FP-1. (even though the FP-1 does that funky octave-down thing, so do a lot of other circuits) Has anybody built this version?
