No pics, but I got a few parts from SBP that I was missing for builds I need to finish up. While I was at it I got a few of the AC128 rejects they had. Just tested with the TC-1 so these measurements surely aren’t too accurate, but anyone have suggestions for any of these guys:
First 3 were rejects for high leakage, other 5 were rejects for low gain. I’ll test em with the RG Keen method for more accurate results at another point, but it should be a ballpark estimate. I’m thinking the one with 906uA leakage will make for a nice decoration 
| Gain (hFE) | leakage (Iceo) | leakage (Ices) |
| 69 | 227uA | 24.2uA |
| 167 | 906uA | 47.1uA |
| 113 | 353uA | 31.4uA |
| 45 | 146uA | 24.2uA |
| 40 | 106uA | 21.4uA |
| 45 | 114uA | 15.7uA |
| 47 | 217uA | 27.1uA |

Anytime I use the "after dark" OSH option (not super often because of the price, but for special occasions) I either avoid using copper pours or I reserve them for the bottom layer only so you get the classier copper/black look on top. Your circuit is a lot more complex than mine though

This was a custom job for the guitarist in my band, he had a pedal he loved the sound of (Rangemaster) but wanted a version with lower noise. I only built 2, the third PCB is floating around my workshop somewhere.

The hFe 113 transistor should do well as Q3 in one a Tone Bender Mk. III/Buzzaround/Dizzy Tone type circuit. The hFe 69 one is worth trying as Q1 of a Tone Bender Mk. II (those are very close specs to the transistor that I used in Q1 of my favorite Mk. II build). The really leaky higher gain transistor is tricky. In my experience most (but not all) really leaky transistors tend to be hissy. If it's not hissy, you can try using a reverse biased leaky germanium diode (or the collector/base junction of a leaky transistor) to shunt some of the excess current to ground. PNP Germanium transistors with an hFE between ~165 and 200 make great Q2s for Bosstone-type circuits (try one in a Trumpeter, Ermahgerd!, or Teddy Rupture). You'd just need to do some more or less offboard wiring to shunt the leakage to ground.No pics, but I got a few parts from SBP that I was missing for builds I need to finish up.

Here's a Mini Dunlop FF rebuild I did using an After Dark board:

RAD! I wish the mini FF cases were available for sale instead of having to find an old busted one.

Always thought those mini ff were cute. Kinda forgot about them and I like the idea of making a new board for one

It's blue box day! A few new arrivals:
- Mini relay bypass boards! I was inspired by @MattG's relay bypass project, so I decided to take a stab at designing my own relay bypass board. I had them assembled at JLCPCB, including the relays, which I purchased through JLCPCB's pre-order service. Including assembly, shipping, and a coupon, the cost per board averaged $1.02 across 25 boards. I'll be adding the ATTINY microcontroller and 100u cap myself. Including the footswitch, I was able to get the total cost of the switch, board, and parts below the cost of an alpha 3PDT from Tayda. I don't build a ton of pedals or build commercially, so this should keep me supplied for some time.
- Like @WheatAndBarley, I'm a big believer in incorporating over-voltage protection in all of my builds. Looking at various gear-related forums, I see lots of posts where people ruin perfectly good pedals by connecting an 18v supply to a 9v pedal. I personally use a Cioks power supply with external dip switches that can bump the voltage from 9 to 18 volts, so it doesn't take much imagination to see how that could happen. I used p-channel mosfets from JLCPCB's basic parts, but decided to use through-hole zeners because JLCPCB did not have 15v and 9.1v zeners in the basic parts category. The board is designed to use PJ-601B mono jacks that I got from Ali Express.
- One of my favorite builds is a Spaceman Gemini IV clone that I built on a Dead End FX EVA board. It sounds great, but I'm not a fan of the horizontal 1590BB2 layout and I had to make some compromises on jack placement due to the design of the board. So I decided to build my own board for use in a vertical 1590BB2, with a few tweaks:
- Replacing the collector-base resistors in the germanium side of the circuit with trimmers to allow for a wider range of transistor leakage
- Moving the polarity protection off board
- Minor tweaks to the power supply
- Adding a V+ out pad to power the relay bypass board.
- Finally, a Tone Bender Mk. I style fuzz. I like the Kilimanjaro a lot. It's a really neat fuzz circuit and you should go out and build one if you have not done so already. It does the Ziggy Stardust thing really well and it does some other cool vintage fuzz sounds, too. Anyway, so one day I decided to breadboard the circuit to see how it would sound if I replaced the filter stage of the circuit (a potentiometer that adds resistance before a higher value parallel input cap) with different value caps. I realized that I liked that sound better, so after playing with input cap values, I decided to make a PCB that used a half of a 2P4T rotary switch that switches between having nothing, 2.2n, 4.7n, and 8.2n in parallel with a 2.2n cap. It sounded good on the breadboard, so hopefully it'll sound good boxed up!

Never thought I'd build a HM-2 or anything related, I figured I might get the Behringer clone at some point maybe. But I was tipped off about this Finnish one person operation that also sells a PCB of their modified HM-2, so I snagged one up. The actual pedals are also very reasonably priced IMO.

Nice! I came across their website somehow a few weeks ago. I was curious about that pcb as well! Cool stuff

If you take a look at the build documents, that's also very well done. Especially the drill template which includes everything in millimeters which should make it very simple to use Tayda's drill service.

Ya their build docs are awesome. I love the detail and the drill template. As soon as I get some extra cash I am going to buy this board. I like the layout of this one, it leaves plenty of room for artwork.
