Build Reports / A Couple Bass Pedals
« on: October 15, 2020, 10:32:50 AM »
Been trying to box up some of my prototype builds lately. First up is my Sunndering bass preamp and DI. It's based on the Sunn S200 preamp, but with JFETs. 3-band EQ + volume control into a simple opamp-based DI. Graphics I just printed on medium weight paper and mod podged onto the enclosure.

(Drilling for the XLR was a PITA since my step bits stop at 3/4" and the hole needed is like .8"  >:( )

Next up is the Hot BOD bass drive, a modified DOD FX91. Used the Demedash Incandenza bypass scheme (555 flipflop to trigger a relay). Faceplate I printed on my resin 3D printer. Built it for a bass player friend who's in a band called "Midwell" so it's appropriately (appunpriately?) named. lol

Build Reports / DRV Clone
« on: September 10, 2020, 01:33:19 PM »
Here's my take on the 1981 Inventions DRV. The board is the same as the layout on my blog but was my guinea pig for carving PCBs on a small tabletop CNC mill. Enclosure is jank 1590B knockoff with waterslide decals. Wired for buffered bypass like the original. I know there's differing opinions on this circuit, but I jammed with it for a good bit after boxing it up. To me it really shines with the gain turned down and volume up. Like a gnarlier Klon, it boosts your signal and adds a nice bit of snarl that responded well to pick attack. It also sounds good with or without the charge pump. Without it loses some headroom, but is still a great sounding dirt box at 9v. And with 18v it just give give you more headroom and a little more spankiness? YMMV, but I dig it.

Build Reports / Midwell - Custom wooden enclosure content
« on: February 07, 2020, 09:08:16 AM »
A couple weeks ago I went to a house show/EP release party of a local band my brother-in-law works with (he does marketing/web stuff for them). Got to talking gear with the guitarist afterwards and we hit it off. Decided last weekend I wanted to make him a pedal. I ended up going way over board with this, but I'm pretty happy with how it turned out and he was super excited about it. Having quite the dad sense of humor and loving puns, I decided to build a mids EQ (Catalinbread VarioBoost clone) as the band name is Midwell.  ;D A couple years ago I'd started this wooden enclosure with a bent steel top that's just been sitting on my bench collecting dust, so I made the back cover and a plate for the jacks. I drew up custom layout in Eagle and added Steve Demedash's Incandenza relay bypass. Used my resin 3D printer to make the name badge (which got buggered in assembly  >:( ) and threw on some big ol' chrome/black knobs from BLMS.

An in process shot:



I'm going to redo the name badge as the screw holes were just a bit off and made the lower edge bend upwards, not to mention gashing the lower line of text with a screwdriver. But he's excited to use and they're going into the studio in a few weeks, so hopefully it'll be a useful tool in that process. Here's their Spotify link if anyone fancies a listen:

Build Reports / Sunn Beta Bass preamp - SUNNβEAM
« on: October 31, 2019, 08:21:15 AM »
Been wrestling with this off and on (mostly off) for like 2 years. Repeatedly kept screwing up little things, but it's working perfectly now and it sounds awesome. It's the preamp section of the Beta Bass amp in pedal form. On board voltage double/charge pump delivering +/- 15-ish volts, 3-band EQ, lots of headroom and gain on tap.

A few boards are available on my site if anyone wants one.

Build Reports / Barranca Overdrive (EQD Palisades-ish)
« on: October 11, 2018, 07:55:00 AM »
Been working on this one a while and finally got it boxed up last weekend. It's my take on the EQD Palisades, but without the boost option, since I wanted to squeeze it into a 125B. The hardest part was the rotary switches, but I remembered the Coda Effects tap tempo trem build that used some mini 1P6T rotaries (which you can get from Small Bear) with daughterboards to board mount them. Now we're cookin'. I ended up adding another option to the bandwidth switch (Palisades has 5) since you can't limit the number of poles with the minis like you can with the large plastic Alpha rotaries. The rest of the circuit isn't that large, so it came together pretty neatly after that. Because of the rotary/daughterboard combo I had to use long leg PCB mount pots to get all the controls on the same level–well, almost all of them. Anybody know if there are longer legged toggle switches? I ended up using some thick solid core wire to get them high enough to get the nuts on. I guess I could have left them short and had an oval in the enclosure for the throw of the switch, but who wants to mill an oval? lol Anyway, I'll stop rambling and show the pics now.

Here's the daughter boards and mini rotaries:



(Used Mod Podge to adhere the graphics. Thanks CJ for that thread detailing that method.)

Build Reports / Soil Slinger - EQD Dirt Transmitter build video
« on: July 27, 2018, 12:27:09 PM »
I had some Dirt Transmitter boards fabricated shortly after I traced the original, but finally got time to sit down and build it. Filmed while I was at it, so enjoy guys! If you're interested in a board or 2, check out the for sale section:

Also, it's hard to solder when you're trying not to stick the back of your head in front of the overhead camera.  ;D

Build Reports / EQD Dirt Transmitter - A De-build Report
« on: June 08, 2018, 12:45:32 PM »
Not a build report, but a dissection report I guess. Grabbed one of these off Reverb a little while ago and traced it this past week. Made a video while I was at it and thought I'd share it with you guys. Etch-able layout on my blog and it's also on OshPark if you want to go that route (links below).

Build Reports / Speaker Cranker in home brew enclosure
« on: August 29, 2017, 02:45:47 PM »
Feels like I haven't boxed anything up in ages. Last night I got some shop time and boxed this little Speaker Cranker clone.

The enclosure started it's life as Bud Box I found on eBay ages ago. The top broke, so I used the base along with some red oak to make a new enclosure. Painted the aluminum with some textured Krylon (I think? I painted it ages ago) spray paint and then black over it. Might need to make a run to Home Depot to get some screws to keep it together. Can't find any good ones in my stash. lol

Here's the guts. Nothing special.

Build Reports / EQD Hoof Reaper clone
« on: February 22, 2017, 02:03:24 PM »
Finished wiring this up last night. Three 3PDTs in one 1590BB isn't something I want to make a regular habit, but holy crap does this thing sound good. For those who aren't familiar, the Hoof Reaper is a 3-in-1 fuzz. The Hoof is a modified Muff with germanium transistors and LEDs in the clipping stages. The Reaper is a silicon/germanium hybrid Tone Bender type fuzz. Throw in a Green Ringer in the middle and you have the Hoof Reaper. I finished this at like 10 o'clock last night, and it took a lot of will power to not crank it up. Fortunately I did not wake up my kids (or the rest of the neighborhood). Anyway, well worth the build if your a fuzz addict like me.

Build Reports / Bellows Clone
« on: January 17, 2017, 12:00:23 PM »
Before the Holidays I grabbed a used EQD Bellows off eBay. Great sounding dirt box on both guitar and bass, plus soft touch relay switching. Of course before I even plugged it in I cracked it open and took a peak in side. Not too long after I was able to trace it (ignoring the PIC-based relay bypass circuitry). Here's the schematic:

The JFET threw me, so I breadboarded it real quick (with a J201 for the JFET) and it fired right up. I made a layout for my blog and went ahead and built it up on perf to verify it. With the original being in a 125B enclosure, I went ahead and boxed it up in a 1590B with top mounted jacks (or TMJs as Cody and I call them). Smaller footprint FTW. Wasn't feeling all that inspired for graphics, so I just spray painted it orange and painted some flames on there.

For bypass I used good ol' Millenium 2 bypassing with a DPDT (I have a bunch of those lying around).

Build Reports / SS/BS Mini clone for dminner
« on: October 21, 2016, 06:20:59 AM »
Here's another labor trade report. Dan did a great job on the enclosure and I just wrapped up the guts last night.

Considering everything ended up off board, things stayed fairly tidy. Sending it off to you shortly, Dan!

Build Reports / Equinox II Reverb
« on: September 14, 2016, 06:54:53 AM »
Wrapped this one up last night and I'm really pleased with how it turned out. It's a Valve Wizard Equinox II reverb. Instead of a Belton brick most DIY digital reverbs use, this one uses 2, PT2399s set to different short delay times and is set up for tails (which isn't as useful in a reverb as a delay imho, but still cool). Honestly it sounds much better than I expected, and has more depth than the last Belton brick-based reverb I made. Layout's from my blog, btw. Had a friend who does calligraphy do the lettering and it came out really nicely.

Been playing with this one for the past few days. It's a clone of the original 2-knob Crimson Drive by Earthquaker Devices (layout can be found on my blog). Still playing with germanium transistors for Q2. For the enclosure I did a reverse etch of the Emperor's Imperial Guard. I've wanted to do Star Wars graphics on a pedal for a while, and the Crimson Drive made me think of those guards from ROTJ. Big shoutout and thanks to Cody for his help in my little foray into enclosure etching.

Build Reports / Cosmopolitan Build
« on: April 18, 2016, 07:45:23 AM »
Had a lot of fun building this one. Great sounding fuzz and a great layout from Brian.
(Here's a little gif I put together of populating the board. Couldn't get it to embed properly)

Really proud of how the guts turned out. Probably the cleanest wiring job I've ever done. If you're wondering about the board on the footswitch, it's a buffered bypass rig similar in theory to the Cornish buffered bypass but utilizing the Klon buffer instead. Works really well. The layout can be found here if anyone's interested:

Tech Help - Etcher's Paradise / Cosmopolitan - verified
« on: April 08, 2016, 01:22:51 PM »
Built this one up last night. Worked straight away. I used a MP38 for Q3 as the AC127s I have on hand are really leaky. Played at low volume late last night and was really impressed with the sound. Haven't boxed it up yet. Hopefully over the weekend. Great layout, Brian!
