Mode and XLF switches was internal DIP switches in original units but is moved to the outside per Aion Anomaly Vintage Distortion project. Schematic and circuit info is avaiable HERE.

ETI Fuzztone
Designed by Dan Coggins (Lovetone and Dinosaural). Despite its name it is more like an overdrive with asymmetric soft clipping and a tone control that pans between a low pass filter and a voltage divider.

Yamaha AMD-100 American Monster Drive
Pretty cool design; a Rat and a Tubescreamer in one box with a "Contour" control that looks like the Mid control in Wampler Triple Wreck...
...and the requested schematic.

Boss MT-2 Metal Zone
And since this is a circuit that is popular mod platform, here is the layout with component numbers that matches the factory schematic so you can easily identify which component to sub when following mod suggestions online.
EDIT! 201217
Elijah-Baley have created a great mod sheet! LINK!
So now you can socket the whole board and modify it to your taste. :o)
Demo clip of MTKs build.

Boss SP-1 Spectrum
A fairly rare old Boss eq pedal which is rarely cloned due to the dual 10kA/10kC Balance control. However, it is quite easy to make your own if you have a dual 10kA pot and a single 10kA pot on hand. Custom pot tuturial and schematic is avaiable HERE.
Boss FA-1 FET Amplifier
Slightly modified, subbing the two single op amps of the original to a dual. 1458 or 4558 should match the spec of the original ones.

Dinosaural OPA-101 Overdriven Pre Amp
Just traced by Aion Fx as their Ixuea project. This layout is slightly modified compared to the original pedal. First, stock units had a fixed low pass filter before the volume control. The resistor in the filter is now replaced by an external tone control. Secomd, it is wired for true bypass with the input buffer hardwired.
