Okay DIY pedal builders, here is a challange for you.

[TheWoodShed]

What would it cost to make a wet/dry blend pedal with a phase switch and in addition, a good EQ for the clean/dry signal only?

I am not sure is a semi-parametric three band would be better, or a graphic like on the GEB-7?

Discuss...

DIY graphic EQ is difficult just because cutting the slots for the sliders requires a tool most DIY'ers don't have. That's why DIY pedals usually just have pots and toggle switches, because those just require a drill.

You should probably talk to Barge, and look at their website, now that they are supposedly back in business. They already make a blend loop with phase switch, and it should not be a big deal for them to house it in the same box as an EQ of some sort.

Rough guess $200?

You have a couple of options w/this.

I'd base it off a Runoffgroove Splitter/Blend. That'd buffer your signal, split it, and invert one phase as needed.

I was gonna suggest slapping one of those circuits in one of BYOC's 10 band EQ, but it appears to be out of stock.

Maybe $30 worth of parts if you don't go too crazy with the circuit.

I guess here is what I am talking about.

1) true Bypass
2) phase inverse switch
3) 3 band semi-parametric eq on the clean signal only, all three bands sweepable but at a fixed Q.

Last to address is the blend.Is it possible to have two levels, one for the dry signal and one for the wet, instead of single blend pot like on the Barge Concepts?

i'm planning something very similar. 4-band semiparametric EQ based on the 4 band EQ listed here:

with a blendable switchable overdrive section. probably a TS-808 variation. maybe i'll make it external, like you mentioned. the only thing i don't feel the need for is the phase variation...

Sure, it is doable--but the general thinking with these sorts of boxes is that the dry signal "is what it is", i.e. it doesn't need any boost or cut--you do that with your amp. The wet signal is increased or decreased relative to the dry signal.

I've got one sitting right here based off that... dual blend (single loop switchable between 2 blend pots) with a volume and passive tone on the clean path.

Maybe is an active tone control is needed it could be merged with a Mr EQ

I was thinking that since the dry signal was going through an eq chain, the individual level may be a valuable tool to reattain a relative unity.

I bet that'd be kewl as hell.

BTW James, I hear your Thor clips and I'm tempted to grab a PCB and build one w/all these mustard caps I have here. Maybe tweak the EQ section for bass... go all Lemmy Killmeister w/it.
