I am probably keeping this one - the last two I built went to friends. Fun project, and you get a great sounding overdrive that can provide clean boost or saturation. I used an A25k for the presence knob because I was all out of B25k. Maybe do not do that because all of the presence is at the end of the turn. Otherwise this is sensational.

I used all of the correct components with the exception of the B25k potentiometer (I used A). The Led is a 3mm clear in a clear Freznel. I used a 5K6 resistor for the LED. The footswitch is a full size feather click, the jacks are low profile enclosed and the D.C. jack is Lumberg. I socketed the 1N4148 diodes. I used the Davies 1611 knobs. The enclosure is a Tyda pastel green poweder coated 1590b with a waterslide decal and 2k clear.

Everything fits in here if you use the low profile electrolytic caps... PPCB has them and so does Synth Cube. Most of the parts are common, but I listed some uncommon components below.

Notes

1. You need a 2N5457 transistor
2. A 2N7 film capacitor
3. Two 8N2 film capacitors
4. A 120p ceramic capacitor
5. A 560p ceramic capacitor

Great looking build!

I recently build an ODR-1, and I'm really liking it. I've built them before, but always felt the flat(ish) frequency response and/or bass-forward EQ made me disappear in a band mix. But hopefully with the bass cut and actually understanding the spectrum knob, I can make it work this time around. So far so good with the playing I've been doing with my neighbors.

If you have some on hand, try some RC4580 opamps in place of the RC4558. In my build, I originally used good ol' 4558, but then I replaced them with 4580. It could well be expectation bias, but I do think the 4580s make it sound better. At least on paper, the 4580 has much better specs.

What made me take another look at the 4580 was Rod Elliott's "Opamp Selection" article. Which itself is ironic, because he's essentially arguing that in many applications - definitely in guitar effect pedals - any halfway decent modern(ish) opamp will perform as expected.

Either way, if you have some on hand, and you used sockets, it's a fun and easy experiment.

Thanks for checking out the build and for the tip! Turns out I have some JRC4580D from Stompbox.
