Build Reports / Wolfshirt (Foxx Tone Machine)
« on: December 08, 2022, 06:42:12 AM »
Nothing fancy here aesthetically, but I am still quite happy with this build.  This is a Wolfshirt board that I received as part of a PIF, I believe (my memory is as fuzzy as the tones from this pedal).  I've been building somewhat randomly this year, and picked this board out of the pile and said, "why not?"  The octave it produces is quite clear when you find the sweet spot on the fretboard. It is also a nice fuzz. Fun build and fun tone.

In the build doc for the 3PDT-05 bypass board, there is a mock layout drill guide.  However, it should use the image of the top of the 3PDT-05 board rather than the bottom so the LED is in the correct side for drill planning purposes.

Build Reports / Rangemaster with MBP 3PDT-05
« on: November 20, 2022, 05:09:29 PM »
This is the first Rangemaster I have built, and I love it!

The transistor is a Russian МП20 with a gain of 72. The Madbean 3PDT-05 bypass board supplies -9V, so this will play nicely with other pedals.

The knob is polymer clay over a brass insert from LoveMySwitches.

Build Reports / LemonOD
« on: October 31, 2022, 10:07:14 AM »
I'm currently suffering through COVID, after avoiding that germ for nearly 3 years, so I have decided to do a rehouse of an old project with a lemonade theme. When life gives you lemons, make lemonOD.

The circuit is a tube screamer with Landgraff mods, and I added Jack Orman's fat mod as a bonus. 

The left-hand toggle selects clipping: silicon (asymmetric), open, or LED.  The right-hand toggle enables the fat mod.  The knobs (left to right) are: drive, tone, and level.

In my years of building stuff, I have for some reason never made a test harness box.  Now I have.  Meet my lab assistant Igor:

Now I can more properly "rock it before you box it".

Build Reports / Chaos Agent (horizontal layout)
« on: October 16, 2022, 08:07:45 PM »
This is my build of the Chaos Agent.  I am happy to be able to post a working build after my last setback (still debugging that Naughty Fish).  I may add some more paint pen to the enclosure eventually if I can think of a name or anything to draw.

Jimilee inspired me with his recent builds to use a white pen on this. 

Build Reports / Naughty Fish build (almost)
« on: October 09, 2022, 06:39:44 PM »
I have made it through a build of the wonderfully-tight Naughty Fish mutron iii clone.  Only problem is, well, it doesn't work right just yet.  The envelope follower seems to be fine, but the filters either cut out completely, don't affect the signal much, or oscillate.  Some debugging is in my future, but I think it looks nice, anyway.  ;D  I'll provide an update once I get it working.

Build Reports / Pedals for Ukraine - Wampler-modded Distortion+
« on: April 26, 2022, 11:36:18 AM »
This is a work in progress, but it is close to complete.  I just need to figure out what I want to do with the enclosure art.  ::)

Storyboardist generously donated the boards for this project (Thanks again, David!), which is either a Distortion+ or a DOD 250 with mods.  I honestly couldn't tell you which circuit it is closer to now (I didn't build it to-spec, and it has characteristics of both), but it works, and it sounds decent.

I used a handful of Brian Wampler's mods found here:

Specifically, I used the Ge/Si output clipping combination, moved the gain knob to the feedback loop, and scaled some of the parts to extend the gain range.

The op amp is a vintage Raytheon can, for added mojo, of course (I didn't look at the datasheet too carefully).   ;)  I have one more of these cans if anyone needs one (free if you are going to use it in a Pedals for Ukraine build).

Once I get the enclosure art figured out (I'm open to suggestions), I'll have this ready for auction in relatively short order.

Build Reports / WIP: Archibald (needs some debugging work)
« on: April 05, 2022, 01:03:51 PM »
I'm most of the way through building an Archibald, and I really like how meaty this build looks. 

Although a vent over the tube probably isn't really necessary, I couldn't help myself:

That cutout took many hours of drilling, cutting, grinding, filing, filling, trimming, and sanding.  I don't think I would try that again.   :P  The dark gray is JB Weld to fill in gouges and the like from my Dremel.  It will be hidden under paint eventually.

I am, unfortunately, having trouble getting it working.  I have an apparent short between the 6.3V test point and ground.  I'm thinking/hoping it is due to a bad regulator, but I haven't pulled that part off the board yet.  The tube is a TAD ECC83WA.  I hope it works.

Build Reports / Apparently, I'm obsessed with Brassmasters
« on: February 14, 2022, 07:14:54 AM »
I am currently working on my 3rd Brassmaster build, and I already have a 4th one planned. It's a great circuit (opinions vary, of course). As a sort of WIP thread, I decided to collect them here.

Here is the first Brassmaster I built.  It was a kit build from GGG, using a board designed by R.G. Keen.  I was quite happy with it, but I sold it a couple years ago to make room for new stuff, and I knew I could build another one better someday.

This is the one I built as a gift to my brother after he bought himself a bass guitar.  I squeezed it into a 1590B, and it was the one and only time I successfully etched an enclosure.

This is my current project.  Another 1590B build, but this time with 4 knobs.  Again, using R.G. Keen's board from GGG.  I just need to make the box pretty and solder a few things, and it will be done. The fit is only slightly tighter than the previous one (mainly the 3PDT toggle needing to be placed just right).

I was quite excited when Brian announced the BoomBoom.  I have the board in my possession, and I plan to make something special with it.

Several years ago, I cobbled together a combo Brassmaster and OC-2, with the Brassmaster input being selectable from clean, one octave down, or two octaves down.  Those same signals were also mixable with the output.  I really liked it, but in a fit of depression, I disassembled it.  I'm planning to rebuild it and improve upon my earlier version.  Suboctaves into a Brassmaster make some gnarly sounds.

I don't have a pic of the finished old project from before I tore it apart, but I have this partly complete pic.

Hopefully, the rebuild will also fit into a 1590BB.  I have no idea why I used a stereo input jack for a pedal that can't fit a battery, but I'm guilty of having done this more than once.   ::)

Anyway, I plan to add updates for projects #3 and #4 here eventually.

Build Reports / JMK HooDoo Drive in a 1590G
« on: January 26, 2022, 09:25:16 PM »
This is my first build this year, and it is my first time using a 1590G.  It's a JMK HooDoo Drive, based on the Voodoo Labs Overdrive.

The graphics are simple freehand with a Sharpie and a paint marker and some clear coat.

I wrapped the board in some gaffers tape after taking this pic of the guts.

I like the way it sounds.  It's a more subtle drive, mostly clean, but adds some nice flavor.

Open Discussion / NLGD

You're never too old for Lego.

 Came with a Princeton Reverb amp, which I haven't assembled yet.

Here's my old strat for scale:

Open Discussion / NGD (sort of) -- 2012 MIM tele
« on: August 23, 2021, 12:52:53 PM »
I have been appointed (by my brother) as custodian for this lefty 2012 MIM Telecaster.

My brother found it while curb shopping (or trash picking, if you prefer that term--someone threw it out and my brother grabbed it).  It is missing a knob on the pickup switch, the jack wiring is broken, and there is a noticeable dead spot on one of the pots, but it is well within my abilities to fix it up. 

I have been instructed to keep it until a worthy left-handed player needs a guitar.  I am required to give it away for free when that time comes (my brother cited karma as the reason).  So, I get to have some fun fixing it up and hanging it on my wall for now.

Build Reports / Slow Loris (Gearside caption contest prize build)
« on: September 30, 2020, 10:12:23 PM »
After I won the Gearside caption contest, I selected a Slow Loris board as my prize.

Here is my build.  The graphic is my attempt at commemorating this entire year with non-political humor. 

The glyphs below the toggle can best be explained, perhaps, by breaking them into their components:
SS = pair of Si diodes
LL = pair of LEDs
SSS = asymmetrical Si diodes

Thank you again, Matthew, for your very generous prize!

Open Discussion / Recommend a phaser to build? (Help me, Jimi!)
« on: September 29, 2020, 12:14:32 PM »
So, I have this friend who has built lots of guitar pedals, but he is a little embarrassed to admit that he has never built a phaser.  There are so many phaser circuits out there that I am my friend is feeling a bit overwhelmed trying to decide which one to build first.  Any suggestions that I can pass along to my friend?  ;)

Edit: Added the word "first" to soften the mental pressure of having to choose only one.    ;D
