I had a yellow enclosure, and I wanted to build another Zvex Mastotron clone and see if I could squeeze in all the pots, knobs and a switch in an upright 1590B enclosure.
So here is…The Yellow Shark…
This is a clone of the Earthquaker Devices Tentacle – http://tagboardeffects.blogspot.com/2016/11/earthquaker-devices-tentacle.html
Note that there are no pots on this one, just on and off so I decided to make a feature of the (green) LED by putting it in a bezel. It looked naked otherwise.
When it came to do the artwork and theme I wasn’t getting any inspiration from tentacles or underwater sea creatures.
I did some research and found out that it is based off a Dan Armstrong Green Ringer pedal. Then I discovered that Frank Zappa used one of these built into his guitar.
So, with the ingredients of “Green” and “Zappa”, I present to you the Green Hocker:
Green hocker croakin’
In the Pygmy Twylyte
Crankin’ an’ a-coke’n
In the Winchell’s do-nut Midnite
Out of his deep on a ‘fore day run
Hurtin’ for sleep in the Quaalude Moonlight
New pedal day!
This one is a clone of the ZVex Mastotron, a farty silicon fuzz, and the layout is here – http://tagboardeffects.blogspot.co.uk/2012/02/zvex-mastotron.html
When it came to do the artwork and theme I wasn’t getting any inspiration from elephants or suchlike. A few happy accidents later I came up with The Scotoma (see Scintillating Scotoma, something which I get from time to time):
It was a bit of a squeeze getting it all into a 1590B which meant that the toggle switch is too close to the stomp switch, but as I’m not going to gig with it, it will be OK.
I had a neon meate dream of a octafish. And an obsession with the Fuzz Factory circuit, and buying old AC128 transistors. The circuit is simple and easy to knock up, the enclosure and art concept takes longer.
I added a “bulbous” (fat) switch.
There’s a 100nF capacitor going from Q1 to Q2 (C2 in this schematic):
All the switch (SPST) does is switch in another cap (4.7uF) across that cap giving it lower frequencies.
Bulbous also tapered!
(Tin Teardrop would be a good name for a pedal. And Orange Claw Hammer for a compressor or Bat Chain Puller for a delay…or a Booglarizer?)
