If you still want to roll your own, this chart may help . . . .

It sounds the same, but you lose the guitar volume knob clean-up feature. At least, that's how it behaves with mine. The daughterboard is just an after-boost, cuz the original circuit barely achieves unity gain.

Spencer does great service at AmplifyFun. A phone conversation with him is the best way to get started. His file formats are provided when so asked; providing nice templates to get started. He uses .AI, .PSD, .AFDESIGN & .PDF

Out of curiosity, what was it?

I was also under the impression that the '±X%' parameter of electrolytics implied that the tighter the percentage, the quicker, but less fully charged as their threshold of voltage is approached.

The TL074 should have 9V on pin #11 and 3.3V only on pins #3 & #12.

Good to know you had a happy resolution.

Your best bet is include some good, clear photos of both sides of the PCB and all the connections. That way we might better see to provide more help.

Meh. That's just Barry's marketing. If you go with the Mini-Me, ping me and I'll post a modified schematic and some pics for the mod(s).

GuitarPCB has their "Mini-Me" (modified EHX Small Clone clone) that fits handily into a 1590B. I even add a mod to the ones I build and still works well in a 1590B.

Seems legit for high frequency stuff; but doubtful it applies to the voltages and audio frequencies used in most pedals.

I've pre-ordered a few of them from CabinTech Global to try out. After reviewing the datasheet and comparing to other 8-pin DIP BBDs, they are not pin-for-pin compatible. So a new layout would be needed. Considering the SSI2100's power requirements, I do see that it might be possible to create...

That price is available only in quantities of 1,000. :( $4.73 in singles at CabinTech Global (discounts for quantities).

If it has a built-in clock, why does it have a Clock pin (pin #8)?

Some good, clear photos may help too.

In your "Change 3" image, that diagram does not show a ground going to the main PCB.

Have you been reading any material on the FV-1 or SpinCAD? I recommend this link for a more focused look at the Pitch Shift block. And the only reference I have for pitch control is this chart . . . Considering the FV-1 has a pitch limit of 1.2 octaves down and a max of 2.0 octave up, I use...

Open the patch in SpinCAD, right-click on the pitch block and select "Control Panel" Therein are the settings that can be adjusted.

By the description of the problem(s), it sounds like an intermittent connection. I'd reflow EVERYTHING and give it another go. If it still goes wonky, put it on the bench and test the voltages for the +9V and +3.3V supplies and lines.
