Custom builds

Some pedals custom ordered.

Starflyer

Here’s a nice fuzzy circuit I built. Based on Deviever The Soda Meiser and  The Torn’s Peaker.  I did not do the circuitboardlayout for this one but for those who like to try it there’s a DIY projectfile here.

Magic Drive
A simple two knob distortion pedal based on MXR:s Dist+. When the switch is in left posistion the circuit clips over two 1N4148:s, in it’s middle pos’ no diodes, + at the right pos there’s two AA144 and two 1N34 germanium diodes in a slight asymmetrical clipping.

Clone of a Klon
Well, a clone of a klon, made my own circuitboard layoutfor it, the one I found on the web did not suit me. Some adjustments were made after the soundfiles were recorded.

Eko

Eko is an analog delay based on Scott Swartz analog delay, two BBD circuits (V3205) gives about 400mS of analog delay.

3MOVIBR8
3MOVIBR8 is a two effects pedal, selectable by the Trem/Vib switch. The vibrato circuit is based on the Boss VB-2 and the tremolo is basically an EA tremolo

Zimba
A 600mS analog delay, truebypass, built around three V3205BBD circuits. Controls for Level(level on the repeats), Boost(about 24db off volume boost is accesdible), Echoes(number of repeats), Time(delay time), + an internal trim pot accessible through the bottom of the pedal, which controls the total amount of hi cut. The soundfile is contributed by Nut.

Smart Loop

A looper with three “smart” loops,  each activated with a momentaraly switch wich kills the other active smart loop. Only one can be active at a time, all with a master truebypass switch. The other four loops are convential truebypassloops. Powered with 9VDC.

Mad Quacker
A nice yet simple envelope filter. It can be found on the web as Nurse Quacky, but the Zeta Sound version uses it’s own circuitboard layout. The soundclip is not from a Zeta Sound pedal.

Ross Compressor
I’ve tried two versions of this one, one like the original and one with a bright mod. To my ears the bright mod is the winner.
