EarthQuaker Devices Spires Green Channel

 A Rosac Nu Fuzz done EQD style... Heavily modified values compared to the stock Rosac schematic that is floating around online. It suggest that it should have more volume on tap and a tone control with much wider range than its ancestor.

Schematic is avaiable HERE.



EarthQuaker Devices Spires Red Channel

 For those who don't want the whole Spires circuit with all the offboard wiring comes two separate öayouts for each channel. The red channel is a modified silicon fuzz face with some additional filtering and a fuzz control at the input. MPS3704 transistors seems to be not that common but a quick equivalent search reveals that they are NPN silicon transistors with a minum Hfe at 300. So 2N5088s or the BC54x family might begood subs if you don't have the stock transistors on hand.

 Schematic is avaible HERE.

 



Inverted Cross Audio Octaver

 Here is a useful little circuit that can be used before or after your favorite dirtbox. It is basically a Green Ringer  circuit with a buffered clean blend.

Inverted Cross Audio Low Rider

 A candidtade for the ultimate Rat for bass and down tuned guitars? Maybe.

Walus Audio 385 Overdrive

 This one has a pretty interesting backstory. It is supposed to be be based or simulate the tube section of Filmosound projector from the 1950s. After listening t o the demos it seems to be a Tweed style overdrive.

Black Arts Toneworks / DOD Boneshaker layout 2

 There is an old layout for this one in the library that looks like trash so I did a new one from scratch. The Depth control was pretty much useless (factory/design error?) so I rewired it for this layout. Also there was some complaints about the feel and taper for some of the controls. See the suggested changes below the layout.


 
Schematic.

 


Frost Giant Electronics Massif

 Per request. Another Meathead variant with some minor tweaks compared to the original. But it is added to the library for science (and another excuse to build another one knob fuzz😏).
