OMG! So sorry. I only use the EZP2019 for pulling data from EEPROMs. I've never actually used it for pushing data to an EEPROM. It still may work tho - I just don't know. I don't know where my head was when I responded initially. To push data to an FV-1 EEPROM I've been using the SpinASM...

That should do fine.

I use an EZP2019+ burner tool with the SpinASM Assembler for Windows software. Easy-peezy. The link for the SpinASM Assemble is at the bottom of the Spin Semiconductor FV-1 page.

Check this out . . . . . https://www.pedalpcb.com/product/pcb633/ The trimpot can be replaced with an external pot.

Considering the number of sharp solder joints/points, my experience tells me that a single layer of electrical tape alone may not be good enough to isolate the the chassis' of those two pots. The solder joints/points can poke right thru electrical tape. And to be fair, IMO - ChatGTP is not a...

Maybe add the little pads for an SMD mounted device? Then you can come cleaner.

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...
