Hornby Skewes Shatterbox

 Slightly modernized and improved. The original  ran on negative power supply with low gain jellybean PNP silicon transistors with BCE pinout. This layout calls for low gain NPN silicon transistors with CBE pinots so you can easily socket the normal suspects like PN2222, 2N3903 etc. And a trimpot for the biasing the fuzz section replaces a fixed 10k resistor since original Skatterboxes was quite infamous for sounding misbiased in a bad way. And there is a spot for an optional smoothing cap across the base and colllector if the sonic character is too harch to some ears.

So what is this thing? Basically an early example of a multieffect. A silicon Zonk Mk.2 into a silicon treble booster.

Satronik Fuzz Sustainer

A few months ago, Alex and I made an attempt to trace an old polish fuzz/distortion that looked incredibly cool and was supposed to sound in the vein of a Rat or a Big Muff. Soon, we realized that the circuit design was quite unique, not resembling anything else. It is basically a bootstrapped booster into a 741 op amp running way above full tilt for op amp clipping. An offset null trimpot is there to fine tune the gating and the sustain for the op amp. Then the signal goes into a BJT powered Baxandall tone section with the bass control fixed midway. The tone control is the Treble control in the Baxandall network. 

So far so good but we failed just before the finish line...four of the resistor values was impossible to figure out so we pot it to bed. A few months later Blue Colander Stompboxes entered the scene.. They traced two Satronik units and posted a schematic on their DIY section of their website. That helped us fill in the missing gaps!

Note that several cap and resistor values varied through its lifespan as well as the transistor selection. The differences are quite minor so the sonic character shouldn't that far off from unit to unit. The values in the layout below are almost solely from AlexS and mine trace.

Note thjat the Deadend mods that are includued in the schematic are omitted for the layout octave trimpot, starve jumper...).

Dead Air Sawzall

 Another contribution from Chris at CDC Fx! This layout is already VERIFIED and good to go.

Schematic is avaiable HERE and as you can see the drive section is a modified MXR Distortion+ derivate. You can yeasily tweak it to DOD 250 or countless other variations of the circuit.

Not your Tubr Screamer derivate as the name would suggest. Instead, we have a four stage CMOS overdrive with an op amp preamp, a TS style Treble control and a gyrator for the Bass control. Could it be a sleeper?

For a more compact and symmetric layout I subbed the TL074 quad op amp for two TL072s.

 evilarsen is back! This time he traced Swamp Lord by Minotaur. A tweaked Rams Head style Muff with a clipping switch and a Mids control. Nothing new under the sun really but the doom crowd might be interested in this.
