Lectric FX Space Harp Mod

[joelorigo]

I just saw this awesome build report about the Lectric FX Space Harp, a EHX Small Stone. Is there an easy way to use a pot instead of a switch for the Color? I built the GuitarPCB Mini Me (Small Clone) and it uses a pot instead of a switch for depth.

SH2 (SpaceHarp V2) Phaser - Lectric-fx

The SH2 is a 4 stage DIY PHASER project based on the EHX® V2 Small Stone™. This is the version that comes to mind when most players think of the classic effect. Compared to our original Spaceharp project (which was the older V1), this one uses a different input stage, feedback network/color...

I can't answer your question about the color switch, but if you are looking for mods on a small stone circuit, i would suggest to build Aion's Redshift, which features all the popular mods. lowpass + vibrato + 2 stages gives an amazing modulation...

I quote an other forumite from an other forum :

"An interview with John Fogerty indicated that some older Kustom amps would have both of those, and that he was getting someone to make him a custom pedal with tremolo and vibrato.

The "phasefilter" mod for OTA-based phasers accomplishes something sounding sort of like vibrato+tremolo. Comverting two out of 4 stages to lowpass, instead of allpass, and lifting the dry signal, gets vibrato from the two allpass stages, and the mopdulated corner frequency of the 2 lowpass sections tends to vary the perceived amplitude as mids&highs cut out and come back, yielding something sounding like tremolo."

I have looked at that Aion pedal before. It seems amazing. I love the Small Stone and have a vintage one and a Analogman modded 00's. I used to have a Russian one too. It's just that sometimes with the switch down I want a bit more and with the switch up it's too much. And vise versa.
