1981 Inventions DRV

PedalPCB's schematic, info and pcb available here.
This is a buffered effect.
For true-bypass, leave out Sw 3 and connect the rest the usual way.

Fuzzrocious Ram the Manparts

From the source:

Ram The Manparts is a LM386 (a power amp chip) overdrive that we built to allow guitarists and bassists to not only drive an amp HARD, but also to add some textures and features to stand out! The voltage sag allows the user to drop the voltage below 9V, creating a glitchy, sputter, Velcro-like sound. Keep it clean, make it grindier/heavier, or make it glitchy…the choice is yours, dude. 

The pedal has since been discontinued and not the cheapest when buying used if you can find them.

Fortin Amplification Zuul

Original info:
"ZUUL is the most transparent noise gate on the market! Studio quality specifications with simple straight forward operation. The ZUUL’s threshold knob also controls the dynamics of the gate circuit. Perfect for guitar, bass or any signal source as it has studio quality specifications. Use in front of an amplifier or in a series effects loop. Dual colour LED for visual feedback gating action: Green = Open, Orange = Closed, Off = Bypass. The KEY input signal can be directly from your guitar (ex. split from ROACH or SPLIFF) or other signal source which lets you go from clean to high gain without changing the Threshold knob. This powerful feature lets you control the gate with a different signal than what flows through the input/output jacks of the ZUUL. Side switch or internal jumper to change the threshold range if you are injecting a large signal into the input and not using the key input"

ThroBak Strange Master

From the Source:

The Strange Master treble booster now includes both Germanium and Silicon transistors. These transistors are switchable so the user can now get classic Dallas Rangemaster treble booster Germanium tones and higher gain Silicon treble booster tones from one pedal!

ThroBak guitar effects pedals offers another classic Signature Sound effect with the Strange Master Treble Booster, a recreation of the Germanium Dallas Rangemaster Treble Booster used by Eric Clapton, Brian May and Tony Iommi.

In keeping with our ThroBak Guitar effects pedals Signature Sound philosophy Strange Master treble booster offers user adjustments to shape the sound of this effect. Jimmy Page, Jimi Hendrix and Brian May had Roger Mayer and Peter Cornish customize their effects to create their own signature sound. We give this control to you.

As far as we can tell we are the only company offering a Dallas Range Master clone with a bias adjustment. This  allows you to change the character of treble boost from loose to tight. Switchable range allows treble boost and mid boost germanium distortion. Recreate the Clapton Beano tone or the singing overdrive of Brian May to the growl of Tony Iommi with this pedal, its all in there.

Basically, the Strange Master is a Rangemaster with a switch allowing you to selecting between 2 input caps (Treble and Full) and another switch to select between transistors (Germanium and Silicon), and a bias pot to adjust the bias either between the germanium and silicon transistors or give it a little grit.

Keep in mind that the gain of the transistors is going to be paramount in getting it to sound good. I would suggest looking for gains in the 100-120 hFE range for the germanium (just like a regular rangemaster), and something around 250 hFE for the silicon. Also you can play with the input and output caps to get more or less bass. You can also change the Hi/Low switch for a pot to give you a sweep between the 2 input caps.

Creepy Fingers EQ/Exciter

Brad of Creepy Fingers posted about his build of the old SRS EQ/Exciter pedal with a little mod to allow for gain control. The SRS EQ/Exciter is basically a Fuzz Face with a buffer and a mid control. All I can say is this thing sounds HUGE!!!!

Anta Fuzz

First post of the new year. This comes from a request posted in the forum. Not much I could find about this other than it's a Fuzz Face derivative made in the 70's in the USSR.
