PETE CORNISH: TB-83 Treble Booster, Point to Point Layout

I followed a vaguely similar layout to the one pictured at the bottom of the post for the Pete Cornish TB-83 Treble Booster.   

This is a straight treble boost using a silicon transistor - it's going to sound horrible into anything apart from a cranked valve amp, or maybe a valve based pedal.  Given this was in Brian May's rig, think normal channel of a cranked AC30, with this hitting it.  Well maybe you aren't running nine AC30s at once, all running so hard the border on catching fire, but you get the idea.

I used the schematic from Fryer Guitars - link here.  

DAN ARMSTRONG: Red Ranger

Bass, treble and full range boost - a 1970s classic from Dan Armstrong, although somewhat overlooked compared to its more famous brethren, the Orange Squeezer and Green Ringer.

This is one of the first circuits I ever built due to the simplicity, and it's hard to go past as a simple boost with a bit of fattening up of the signal.  

The Echoplex EP-3 preamp doesn't provide tons of gain, but it does work very nicely as a slight boost, or as an always on type effect.   I plan on adapting this to be the front section of a Valve Caster, to provide some extra grit. 

I used the Aion Electronics schematic, as I like the idea of the fat switch, but I did not include the volume control or output buffer.  Pretty easy to add a volume control, I'm sure anyone reading this knows how.

version update:  corrected switch wiring.  pin 2 to ground (thanks Solderholic)

DAN ARMSTRONG: Green Ringer, Point to Point Layout (EQD Tentacle)

The classic Dan Armstrong octave effect - The Green Ringer. 

Great to put in front of a fuzz or distortion pedal.  The Earthquaker Devices Sunn Life pedal is basically a Green Ringer in front of a Proco Rat, with a booster.

Earthquaker Devices have a version called the Tentacle, which is almost identical.  For the Tentacle, just do the following:

Change Q1 and Q3 to a 2N5089 

Change 1.5M resistor to 2.2M

Add 100pf capacitor from input to ground

1N4148 Diodes used

I've left some room on the board for power filtering if needed.

UNION TUBE & TRANSISTOR: Bumble Buzz

The Bumble Buzz is based on the Kay Fuzztone, which is a simplified Univox Super Fuzz.  It's a collaboration between Union Tube & Transistor and Third Man Records (Jack White).

There are no knobs; just stomp and go.  Raw octave fuzz....

ON THE BENCH

I should have cleaned up the edges a bit - but hey...  it was a quick and dirty build. 

ON THE SCOPE / FFT

440hz sine wave, approx 130mv TRMS

A very distinct octave can be seen, along with a lot of high-frequency content.  As you can see, the actual trace here, is almost identical to the LTspice sim shown below.
