    I left myself a little extra room on the board for mistakes, so I should be able to add mods in there. On a whim I also picked up the Guitar PCB special "boost" sale package of 4 PCBs they had earlier this week that has a modded Peppermill board (they called it Blues Power or something like that) in case I totally futzed up the tagboard since it's so old. I had one pad come up on me, and it wasn't from too much heat, the lead moved when I was soldering and up and away came the pad.

    With a little luck I should be able to fire it up over the weekend and see what it does. So far I haven't found any gremlins with the basic wiring, but that doesn't mean anything lol.

    I also made mine on the ROG perf way back when it was the only layout available. I added the changes after I had already built it so I designed the tone controls to minimize the changes needed to the ROG layout. There is room on the board for the bass cap without any alterations if the cap is small enough. I used a tiny tantalum cap, but you could easily fit a a regular electro cap in there, maybe a box cap. Green chiclets need not apply. The treble control doesn't require adding anything extra to the board. You just need to rewire it to the pot.

    Unfortunately, I'm not going to make it any easier for you to resist the temptation ;) Since I started building pedals about a year ago I've found it takes some of the pressure off the urge to build amps. Pedals take up less space in my increasingly crowded guitar room, and they are a lot cheaper to build. Since I started building on vero and ordering my parts from Tayda (except stomp switches which are somehow cheaper on Amazon), I figure most pedals cost me between $10 and $20 to build, compared to $200 to $500 for my amp builds depending on the design and quantity of new vs harvested radio parts. Pedals are definitely more cost effective per hour spent as a hobby, and they are pretty easy to sell off if you don't bond with them or get bored and want to turn them into money to buy more parts.

    Yeah baby, this thing sounds great even before modding it! Only made one mistake, not bad for +20 years since i last did a tagboard, a stupid one too, forgot one pin to pin connection on the trimmer :oops:
    It biased up pretty darn close to the ROG published voltages too. I also went with a generic J201, I was going to try the PF5102 but I just got a bunch of J201's in the last order. Interesting that a generic part sounded better than genuine Siliconix. I didn't go through all the devices, just a few of each. The BS170s all pretty much measured the same in circuit.

    Now the fun part... :twisted: drilling the enclosure, no paint though it's a black transparent powder coat. Scan the antique matchbox for the decal, print, clear coat that, apply, clear coat the box and wire...phew. Somewhere in there I'm going to try some mods!

    Just finished up the Peppermill...I only included the gain increase on the input stage so far by adding a 1K resistor in parallel with the original.

    Man, another with four pots, I admire your drilling skills! I have enough fun with three lol. And I have to color code my wire or I'll get lost, but I love the way a single color looks, nice and neat.

    One of the pots and the LED holder were actually off-centered, just a tad hair. I had to file on one side to line them back in and to cover the flaw. :D

    Just a wild guess, but I'm thinking it's probably a good time to order some more vero board.

    Got a wild hair to paint this one purple:

    Naga Viper clone board from Jeds Peds in the UK. I was going to do a Vero but I confess, I got lazy :D
    Fun part will be the decals...the purple is too dark for homemade clear waterslides so I'm trying something different.

    Making more progress...I've wanted to build this Spaceman boost for awhile, and had the old mil-spec LED hanging around since the 1980's waiting for just the right build. The drill layout was a hoot, whew, managed to get it all to fit, including a battery.
    First time for depletion mode MOSFETs too.
    Waiting on some silver decals for the Naga Viper, and I'll start the Spaceman decal tomorrow, now it's time for a cold drink :D

    Decals for the Saturn V boost came out pretty good. Took a long time to get them where I wanted, but I think it'll be cool on the chrome powder coat.
    Speaking of, the chrome powder coat looks terrific in person, though it shows hairline scratches just as easy as a polished enclosure. I have another polished aluminum box for the Lovepedal Karl fuzz build that is in the queue, but I don't know if I'll go that route again. Paint or regular color powder coat doesn't show those scratches!

    Well... I had to put my pedal building on hold for a few months. I was 3 parts short of completing my Zendrive but I got really sick and everything went on the back burner. As soon as I started feeling better, out came the solder station and I made all new interconnects for my pedal board and today I managed to get to the electronics supply house to drop a bunch of dough on parts. I usually buy lots of spares so if I need 1 transistor, I’ll buy 10.

    Anyway, I now have the 3 caps I needed for the Zendrive and it’ll go together quickly. I’ll also Rebox my Timmy and I have a couple of new ones I’m building.

    I’ve got all the parts collected for a Proco Solo and a Earthquaker Devices “Black Eye” which is a clean boost like a Super Hard On pedal. I’m also looking to build a Keeley Katana Boost. I’m intersted in a clean boost for soloing.

    I’m also going to build a DSM Noisemaker OmniCabSim. I’ve never built a can simulator and it seems like a cool project.

    I’ll post some results if I can get some decent boxing up happening.

    I didn’t take any gut shots of the box and pots for the Zendrive but I’ve got it all wired up and ready to add the board. I’m going to see if I can get mine as neat as the ones @cacophony does. I bought 6 or 8 100ft spools of very light gauge hookup wire and it’s so much nicer than the stuff I’ve been using.

    Here’s the board. The hold up was the 2 blue 470nf and the single green 3.3nf cap. Everything else I had in my parts bins.

    Had I been really thinking, I would have socketed the diodes so I could try a bunch out and select the best pairs. I’ve been stockpiling germanium diodes by ordering a lot of 20 or 50 when I see something interesting. For clipping it’s supposed to have Bat41 diodes. I understand that 1n34’s are a good substitute for those but I’ve gone with a different recipe as recommended by someone on Tagboard Effect’s. I’ve got a pair of 1n4001 and a single 1n34 germanium diode. My opamp is a JRC4558DD. I should have it fired up this afternoon providing I can get a good neat install of the board.

    Well, I’m back in the saddle :cool:

    I connected and boxed the Zendrive up and it went together without much fuss.

    It’s a very civilized overdrive. It doesn’t seem nearly as gainy as a Timmy but it has a nice tone to the drive. With all controls at 12 o’clock, it sounds like a TS9 with the same settings. Using the Voice control you can make the tone quite unique. It stacks really well and it injects no unwanted noise into my rig. I put a TS9 in front of it and it plays with it really well.

    I pulled out the JRC4558DD and put in a TI OPA2134 thinking that it might have more gain on tap but it’s not a huge difference. Any difference seems pretty minimal and I doubt anyone would notice. I wouldn’t mind a little more gain so I’ll review the Timmy and see if I can adjust components to get a little more get up and go from it. It’s supposed to use a AD712 or an OPA2604 so I’ll need to source those and give it a whirl. It’s a really nice well behaved, creamy overdrive. I’d make another and gift it to a guitar player. It’s a keeper.

    EDIT: It looks like swapping out the 500k gain pot for a 1meg pot will give me the gain boost I’m looking for. I’ll make that change in the next day or two.

    Gut shots!

    Here I’m wired for true bypass with a DPDT footswitch and I’ve got all of my pots wired up and ready to go. The yellow wire pigtail on the footswitch will go to the sense wire on my millennium bypass LED driver board. I still have to add that to the mix. It’ll be a pretty simple addition.

    This is where it’s supposed to go.

    Done! All wired up and ready for action. It fits really well. This might be the best layout I’ve used from tagboard effects. I put a dab of hot glue on the piece of insulating card stock and mounted it to the circuit board to protect it from shorting. There’s loads of room. I even wired in a 9 volt battery because, why not!

    Very nice, clean layout! Love the case artwork too, decal?

    I bought a used Zendrive right before I started building. Thankfully I got a good deal on a used one or I'd be mad at myself for not DIY'ing it. It's a great sounding circuit for lead, I wish I was a better lead guitarist, I'm mostly rhythm and love the Timmy for that.
