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.
