Who can build me a pedal with just the filter section from a EHX bass Microsynth

[matybigfro]

I really love the filter section of the old Electro Harmonix Bass MicroSynth with the Sliders to control Trigger, Attack Delay, Resonance, Start Freq, stop Freq and Rate but don't need the Square wave, or octave voice controls as I have Octave and fuzz pedals that take care of that. I can't see any Filter pedal onthe market that gives similar performance to the Microsynth but buying the EHX for only half it's functionality seems pretty much a bit of a waste or overspend

Anyone here who could knock this together for me or point me int he direction of a builder that has teh skilzz for it?

You'd be cheaper buying a used microsynth. Trust me on this...

sad but true.

Definitly cheaper to buy a MS

Si

I would buy one of these too.

I had a look at the MS schematic - the square wave and octave circuitry 'savings' would only be a handful of components as these outputs are kind of 'side effects' from the processing the rest of the pedal does. It would be cheaper to buy a MS and rehouse it without those controls than to do a one-off custom project.

Them that do the Microthumpinator - Sfx is it? I'm pretty sure they do custom offerings; can't see it being cheap though.

I used to buy components and build electronics gear. Until I did the maths and found I was building cr@p where I could buy good gear from a shop for less cash.

[Bigwan]

It can be cheaper to diy, but only if you don't count your own time. That's where you'd be crucified by a custom builder.

Well that's disappointing. I've opened up a few to do mods and there's two massive boards in there, one on top of the other, so there's no practical way to rehouse it in anything significantly smaller if most of that circuitry is necessary for the filter and envelope trigger.

I've uploaded an annotated version of the relevant part of the schematic here, with the octave output slider section circled, and the square output slider section 'squared':

The (4) and (5) lead to the VCF - you can see there's not much 'savings' from eliminating these parts. OTOH, there's not much being 'wasted' by having and not using them!

If you really wanted this project to happen, your best bet might be to find a few others who are also interested and approach a builder. This would let the builder spread the design work, PCB costs etc across more than just one end unit, and without them taking on the 'risk' of trying to make it a commercial product.

Well I guess the Micro Synth is just gonna have to go on the GAS list now then

Thanks Bass Chat my wife will not be ammused

Thread resurrection. I've had this very thought recently. Tom at Cog Effects would be my first port of call.
