2in1 Pedal: Horizon Devices Precision Drive + Spaceman Effects Atlas III Booster (HGE Contraptions 177th/178th circuits built)

Yet another awesome 2in1 pedal: Horizon Devices Precision Drive + Spaceman Effects Atlas III Booster

The Precision Drive is without the noise gate circuit and my version has actually 8 attack controls on the rotary.

Colorsound One Knob Fuzz variant (HGE Contraptions 176th circuit built)

For fun, I had some leftover parts which are old/used & measuring somewhat in tolerance, and decided to see what happens. I socketed the transistors and used in the end (after MANY MANY tests), a MPSA12 in Q1 and - Germanium 2N1891 in Q2.

In parallel to the 22uF cap I put on a switch a 1000uF, to have a kind of a "fat gating option". Very cool and powerful sound from such a small enclosure! Can get similar tones to Edwyn Collins - A Girl Like You, or Jack White in Another Way to Die, QOTSA stuff. 

The actual tone you get seems to be really dependent and varies greatly based on the pickups, touch, what amp you use, etc.  It really transports you back to the 60's/70's, so much fun!

2in1: BOSS FA-1 + TC Integrated Preamp handmade clone (174th/175th HGE Contraptions circuits built)

A very nice duo to have, each has a slight different flavour to it. Both are discontinued pedals, as far as originals go. I actually use a voltage tripler at the input for these two, made in a separate external 1590A enclosure, to give them 25-27V, way way better sounding.









Ibanez Mostortion MT10 handmade clone (173rd HGE Contraptions circuit built)

Mega nice sounding, with the NOS original Harris CA3260E chip!











EarthQuaker Devices Disaster Transport Jr. handmade clone (172nd HGE Contraptions circuit built)

Traded this build with someone for two original MIJ pedals. I managed to source the original old Taiwan NOS PT2399 delay chip 😃 very cool. A fast boring iphone video take:

HGE Contraptions Voltage Tripler (171th build)

 Simple but effective voltage tripler. Super useful for some boosts and preamps that benefit from the higher voltage for more headroom and loudness.

9V in ->> 27V out
