[0.15″ pitch veroboard] Colorsound – Power Boost / Overdriver

Two different effects, shared (almost) the same component layout.

Very lush sounding units I must admit.

As most of effects from Colorsound line classic and adored!

Power Boost was recently reissued by Macari’s with Castledine  Electronics colaboration

Transistor info: Factory schemo shows BC109C’s but AFAIK those ware never seen in reality. What we see usually is BC169B’s or BC349B (and mix of both) in vintage units, and reissues with BC184L (also seen in vintage Powerboost) or BC184C. Use any NPN Silicon’s with similar spec.

Big hug and high fife to monkeyxx from FSB forum for cool mod ideas.

What you get below is two versions of Power Boost named as Early, and Later spec, and an Overdriver. Another three docs contains the same shit, but in different flavor as per monkeyxx instructions – added master volume control, changed drive pot taper.

Taste it, you’ll love it

Diaphanous Exploder

I was working on this circuit since 2006. It’s completely new design, never seen in effect pedal industry ever before. Surly I took little from other designs, mainly from different 70’s mixing consoles.

So What it is?

Diaphanous Exploder.pdf [click to download] is transparent booster (or boobster if you push it harder), skill driver/shifter, and penis enlarger.

This short description says all. Idea behind this project was to have three pedals in one with minimum controls. I did flow with current fashion during design to build as much transparent pedal as possible. If you ask me, you can’t get much closer in transparency field as this!

Also, what I was missing searching over past few years for perfectly balanced and transparent boobster/overhype pedal is to have more control over speed and feeling. Here you can set perfect balance between that two with just one twist of single knob. How fucking cool is this?

Layout shows full off-board wiring, with shielded in/out jacks. No mains socket, you really have to run it from single carbon battery for best performance. Use 2W CC resistor for perfect sound/noise ratio, and have fun!

EDIT: No, I’m not an diabetic 😉

It was April’s Fool project 🙂

[0.1″ pitch stripboard] D*A*M – Red Rooster RR-09


Yo! Here’s D*A*M take on Dallas Rangemaster – Red Rooster!

It’s classic treble booster circuit with added capacitor input blend and trimpot in place of 3k9 resistor on transistor emitter for better bias.

First roosters where made with excellent NPN germanium transistor CV7112 (military specs OC140). Later NPN units sports OC140 or OC139. Most recent PNP versions are equipped with many different transistor types – OC71, OC72, OC42, OC45, Magnatec AC128, CV7355 and CV7004.

Usually low leakage transistors in 70-100hfe gain bucket are recomended, but You can try other transistor types or specs – trust Your ears, not eyes 🙂


Due to D*A*M counterfeit pedals that recently appeared on the marked all D*A*M straight layouts will be removed from turretboard.org and will be replaced soon with our own works and interpretations.

[point to point, tag board] Pigdog Driver


I don’t know if any of You are familiar with Pigdog Pedals… If not – You should! Steve’s work are always true art of work – for ears and for eyes, as well.

Here’s lovely point to point layout for Pigdog Driver, which is… Yes! Treble Booster with added input capacitors blend. This allows to achive stock treble booster tones or even full boost! Additionaly output cap is increased. All other circuit components values are stock. There where builded 11 units in total and few more in smaller enclosure.

All Drivers are filled with mojo parts and rare germanium transistors and dedicated to british racing legends.

Some even sports legendary yellow Mullard OC44 or ultra rare OC70!

Have fun!

UPDATE 24/03/2012

Added tagboard version – get the project file here [.pdf]

It’s not the same layout as used by Steve in his Mini Drivers, but has the same specs.
