I added a 100ohm protection resistor across the trimpot and the lamp driver transistor (Q1).

DOD Compressor 280

 Yet another compressor, this time an optical one. The specified vactrol is quite expensive and hard to get hold of nowadays but you can roll your own using a LDR with 1M dark resistance and green diffused LED.

Ross Compressor

Requested by Tom. 

It is based on MXR Dyna Comp but has some extra bits mainly for addidtional power and Vref filtering for Q1 and the OTA IC. So I had to add two extra rows but it will still fit in a 1590b box without problem.

MXR Dyna Comp

 Figured out after doing the Aion aurora a couple of days ago, why not doing a layout of its ancestor, MXR Dyna Comp... 

Aion Fx Aurora

 This one has been requested a few times by now...;-)

Aion Fx Antipode / Roland AF-60 Bee Gee

 Aion Fx take on a pretty rare, forgotten and old fuzz box by Roland. Some useful addons is made. A gain control is added and a series resistor before the volume control is removed for more overall output. 

I added a tone selector switch for the tone control since the factory schematic and Aion's schematic differs in that spot; the low pass filter cap in the big muff style tonestack toggles between 1nF(Aion mode) and 10nF(stock mode). The switch acts a Mid/SCoop switch.

Ibanez FC10 Fat Cat

 Similar to the LA metal but this one is closer to a rat with its hard clipping diodes and two RC filters. Schematic is avaiable HERE.

PSK SOD-2 Super Overdrive

 Not a Boss clone as one would assume, more like a Rat with asymmetrical soft clipping with an inpt buffer. Schematic is avaiable HERE.
