    Just did a quick rundown of the parts to build the OC-1. It would cost over $150 to build because of all of the 200qty resistors I’d have to buy. Guess I’ll wait to see if he does a kit version.

    You’re doing it wrong, none of the resistors should be over twenty cents in single quantities at Mouser or Digikey.

    BTW, Rob’s show stream is live right now.

    Many of them were only available in 200qty. They were $0.02 each, but you have to buy 200. One of them only came in a 1000qty. This was on the Mouser site.

    I guess maybe I need to teach you the ways of spec’ing subs, that has never ever happened to me that I can recall, at least for basic 1/4 watt resistors. Which one was a 1000 piece minimum order? To be honest, I haven’t really looked at the OC-1 schematic very thoroughly, but my friend said he had like 40 bucks into the parts to stuff the board, not counting the board itself and the case. But I think he probably has a big parts stash, so like me he wouldn’t need to buy the more common value resistors.

    Anyhow, when I get around to ordering the OC-1 parts I could maybe double up the order and just send out a whole kit to you if it ends up being something you want to buid. It’ll probably be at least a month or three though.

    I don’t recall which one was 1000pcs. I just plugged in the part numbers from the Mouser parts list he has for the pedal.
    I’m in no huge hurry.

    Ah, gotcha. In most cases with resistors there will be at least half a dozen good subs for any given part number. Different manufacturers, different tolerances, and near values that will work every bit as well in a given circuit. Not always true though, of course. I’m here to help if I can in any case.

    OK, I tried calling up the first resistor’s part number on his bill of materials. That gives you what you saw:

    https://www.mouser.com/productdetail/xicon/271-200k-rc?qs=crciVTC1MmHmapJBYEuTLw%3D%3D

    FTN, I don’t want to buy 200. So let’s do a Mouser search on 200K ohm 1/4 watt 1% metal film resistors in axial format:

    https://www.mouser.com/Passive-Components/Resistors/_/N-5g9n?P=1yzbpodZ1yyxf87Z1yzekiwZ1z0wljoZ1z0z819

    Now let’s sort by cost, and here’s my apparent winner:

    https://www.mouser.com/ProductDetail/KOA-Speer/MFS1-4DCT52R2003F?qs=iPPgFPFs9PMnoXEzUXxIGA%3D%3D

    But a quick look at the dimensions shows it’s a shorty, and you don’t want to be like Amy and have a shorty. So let’s be big spenders and go from ten cents to nineteen:

    https://www.mouser.com/ProductDetail/KOA-Speer/MF1-4CCT52R2003F?qs=KVzGhl%2FcVV2gKHLj%2FZEOAw%3D%3D

    BAM, you’re a chick magnet now. You can probably work through matching KOA pieces in that line for most of the rest now without going through this New Jersey fire drill every time. Dig?

    But if for whatever reason you just have to use a Xicon piece (it’s slightly shorter, for example) this was on my search list at 22 cents:

    Ok, I’ll try the cross referencing plan and see how it works out. So, as long as the values and dimensions are the same, they should be fine?

    I think I’ll probably still order the MXR M-82 clone from the Effect Pedal Kits folks once I get my bass back from the luthier.

    The most important specs are value, size, material config, wattage, and tolerance. You want metal film for lowest noise, 6.3-7.5 mm for size, and 1/4 watt, unless the BOM spec says otherwise. The shorty ones actually usually fit OK but I prefer the matched look personally.

    So Jeff did you ever try one of these kits out?  They look interesting.  I’ve not done and board soldering in 20 years but I might give it shot.  But at one point I working in a shop hand soldering 20+ boards a day.  So, I might just find out how shaky my hands have gotten.  Anyhow, share your results

    I haven’t yet. I got a good deal on an MXR Envelope pedal, so I relented.

    Not a fan of my octave pedal, though. I might try one of those.

    <p style=”text-align: center;”>I’d struggled with a case for a GGG a/b/y pedal, as my drill shredded the metal box I was planning on using as an enclosure.  So, I relented and bought a premade EHX Switchblade.  But now I still have the guts of the GGG set and have been searching for a pre-drilled enclosure for a while now.  Any recommendations?</p>

    2 switch holes, 3 1/4″ LED holes, 3 3/8″ holes, and 1 1/2″ hole.

    I emailed GGG but they haven’t responded.

    Do they do one-offs?  All I can find is a price for 25 or more…
