Maestro
MAESTRO: FZ-1 Fuzz-Tone
I guess this is where it all started – The Glenn Snoddy Fuzz-Tone. I modified an existing MKI layout on the larger vintage size vero for this, sized to fit in a wedge enclosure. Initially, I was going to do the original layout used, but it was a bit of a mess – as was the practice … Read more
Maestro MFZT-1 Fuzztain
Per request. A slightly modernized take on a Moog designed Fuzz/compressor hailing back from the 70s. The signal path remains true to the original but the rotary switch has been removed in favour for a variable fuzz control. And the two compressor settings is now fed through a toggle switch. The CD4007AE IC might be … Read more
Maestro Fuzz Phazzer FP-1
The layout is based on Brian Kepharts modernized version of this weird, fun and old device. HERE is a link to a very detalied description of this circuit, schematic, bias setup and explenations of the small but useful modifications.
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 … Read more
Maestro OB-1 Octave Box
Another old octave down circuit with a forest of transistors…. It also have a rare part, MFC-4040 which were a 4.pin divider/flip-flop IC. It went obsoltete in 1975 but according to several sources, NTE754 is a direct replacement. R12 and C21 is marked as “factory tailored component” in the factory schematic so these needs to … Read more
Maestro RM-1A Ring Modulator
A requested circuit but bear in mind that it is rather big, has an onboard charge pump for 15v-15v operation, and has a quite complicated setup due to five multiturn trimmers. I’ve omitted the (for now) the Osc, Pitch, Carrier and Modulation jacks but might add it later on if is requested but it will … Read more
