I like this one.  Best part is that it is USB powered, no screwing around with batteries.

In case anyone is interested, I've made up a demo of this guy.

Was wondering, what is the vactrol for? 

The Vactrol is to convert the normal Dual Gang Speed pot to a Single Gang speed pot (which then can be wired to an expression pedal).  I took the idea from Brian's Harbinger 2 and RG Keen's UVICS (Univibe in a Crybaby Shell) document.

Here is the last build of 2022 for me.  This is a continuation of my artist-pedalboard-in-a-box series.  This time I put together a build based on David Gilmour's Dark Side of the Moon pedals. 

For the majority of Dark Side tones, Gilmour used a combination of Fuzz Face, Overdriver, Uni-vibe and Echorec (along with a few more, but those are the bulk of tones).  The pedal starts with a modified Silicon Fuzz Face (I used the Lunar Module as a base for the Fuzz).  This moves into a Powerbooster circuit ran at +18V.  Then it hits an effects loop if you want to add other pedals and then onto a Uni-Vibe circuit.  This is the same Uni-Vibe I used on my Gypsy (https://www.madbeanpedals.com/forum/index.php?topic=34170.msg327607#msg327607) pedal.  It sounds really good and vibe-y and the addition of being able to use an expression pedal really adds to its versatility.  The Delay portion on this is a multi-head PT2399 delay I've been working on based on the Binson Echorec.  Its taken a lot of inspiration from the Skidmark Sonomatic and DiabloChris's Sagan Delay.  It has basic controls for Mix, Swell (Feedback) and Delay time, with 4 switches to select what heads are active.  Unlike the Echorec with a max delay around 310-340ms, this goes up to about 800ms. Each head compounds into the other, so the ratio's of all delay heads are the same as a true Echorec.  When you have multiple heads active, it creates a really cool sounding effect, something you don't hear anywhere else.

All in all, this is a really cool pedal.  I'm really happy with how it turned out, and even if you aren't looking for Dark side tones, I think that it would be a very versatile grab-and-go pedal that would work in plenty of situations.

These all look great! The Kavana especially looks like a cram.

What's your approach to surface mount? Do you just use a fine pointed iron and a magnifying glass?

I have an even better SMD approach... I let JLCPCB do it for me :)  Yes its kind of cheating, but it makes it so much easier (especially on some builds where I use 0402's).

Build Reports / Phaser-Palooza! (and other builds)
November 03, 2022, 01:41:06 PM
Paging Jimi here...

Here are a few of the builds that I've finished up in the last few weeks.  It turned out I was on quite a phaser kick :)  No matter if you like JFET, Optical or OTA phasers, I have you covered...

Lumina - The Lumina is a take on the Phase 100 circuit.  It is a 6-stage optical phaser.  Instead of using VTL-5C3/2's I went with the roll your own method.  I made sure to add a second pad on the PCB so I could use two LDR's for it (the LDR's are just the basic ones from Tayda, nothing special).  Instead of the 4-way rotary switch like on the Phase 100, I have two switches to control the Feedback and Intensity.  Its a great sounding and chewy phaser!


Burden - Instead of an optical phaser, the Burden is based off of the Boss PH-1R phaser.  This is your typical JFET phaser, pretty similar in sound and feel to a Phase 90.  If you like the sound of that one, you will feel right at home with this!  The added controls for Feedback and Depth really make this a versatile phaser.


Ganymede - Next up is the Ganymede Phaser.  This one is a 6-stage optical phaser, pretty similar to the Mutron Phase II.  I know a lot of people consider that their absolute favorite phaser, and with good reason.  Thick and chewy, it has something special that most phasers just don't have.  I added a 3-way switch to let you choose between 2, 4 or 6 stages of phasing.


Kavana - And rounding out the Phasers is the Kavana Phaser.  This is based off of the Bad Stone phaser.  I wanted to work up a phaser that was simple to build and I didn't have to worry about matching any JFETS or worrying too much about LDR specs.  The Kavana is a simple to build and setup phaser that has lots of cool sounds in it.  The Phasing is pretty simple with controls for Speed and Feedback.  I also have a Manual control and switch, which stops the LFO and lets you set the phase point.  Its a cool feature, but one that I'm not sure I would use a ton.  Other than that, its another interesting sounding phaser.
 

Machine Gun - And for good measure, this could (kinda) fall in the Phaser camp.  The Machine Gun is a 2-in-1 pedal with a Silicon Fuzz Face feeding into a vibe circuit (based on my Spiralizer circuit).  The Fuzz side has a 4-way tone rotary switch to give different voicings, as well as a Thick control to set the input tone.  I also added an order switch for those that like the vibe first.


Vaporizor - The Vaporizor is based on the Boss VB-2 Vibrato circuit.  I've always loved this circuit, and its taken me a while to figure out how to make it work in a mini.  After a few revisions playing around with the switching, I was able to make it so that the pedal will work in standard "push the switch and its on" mode, as well as a momentary mode with the ramp switch.  The throb of this can get really deep and seasick, so its not for everyone, but using the momentary mode to really add some texture, its something that nothing else can replicate.


Legion - I've really been on a kick of making multi-effects boxes lately (See my Gypsy and Six-Shooter builds, as well as my upcoming Brick build), so this is a continuation of that.  The Legion is based on the Ibanez UE-300 box.  It contains an OTA compressor, similar to a Dyna-Comp, a Tube Screamer and a CS-9 compressor (in stereo).  I really like this setup here.  The Compressor is super quiet and does a great job of pushing the tube screamer, and having a stereo output with the chorus adds a huge spread to the sound.  Plenty of jacks on this one; 1 input, a Send and Return Loop, a dry output after the compressor and stereo outputs on the end of the circuit.  Next up is one based on the UE-305 which swaps the Tube Screamer for an analog delay.  I just need to build the board up for that one.


Star Chambre Delay - I've had this one finished for a long time, I just now actually got around to boxing it up.  The guys at Lectric-Fx did an awesome job at this one.  Its an analog delay, but it has something different than a typical DM-2 based delay.  I can't put my finger on it, but something about this delay is special, I love how warm and organic it sounds, definitely a recommended build for anyone!

Looks great!  Sometimes a relatively simple tube-screamer is all you need!

Feel better (if we are talking about the worst symptoms we had, losing smell and taste was the worst for me, hopefully you can avoid that)!

Super cool! Custom boards I'm assuming. Probably the only way to get eveything in there.

That is correct.  I could have done separate boards for everything, but I find it so much cleaner to do one big board (well, two stacked in this case) for everything.

This is super cool! What are you planning for the page and gilmour ones?

I know a guy that would love to shoot a demo of this. ;)

I'm pretty excited about the Page and Gilmour ones.  The Page box is like the much larger one I did a few years back.  It will have a Tone Bender, Phase 90, Delay, EP-3 Preamp/Boost and a RAH overdrive.  I'm doing a Dark Side and Wall inspired Gilmour board.  The Dark Side board will be a SI Fuzz Face, Powerbooster, Univibe and a Binson style 4-head delay (I just ordered boards of just the delay today and it should be super cool if it actually works).  The Wall inspired board will have a BMP, a Cornish Overdriver (like the Aion Sigma Drive), a Dyna Comp, an Electric Mistress and a PT2399 delay.

And I might have to take you up on your offer of a demo for this... ;D ;D

Build Reports / Schu-Tone Gypsy
September 26, 2022, 01:00:46 PM
Here is something that I put together this weekend.  I've had the idea kicking around my head for some grab-and-go type boards for a while now.  The Six-Shooter that I posted the other week was a sort of start of that.  I've had a thought for a Hendrix inspired board for a while, but never went ahead and implemented it.  The Gypsy is what I came up with.

The Gypsy is housed in a 1590DD enclosure, and there are 4 circuits in the box.  The first is a SI fuzz face.  Pretty basic SI fuzz, with an added Body (input cap blend) and Contour (mids) control.  This goes into a Roger Mayer Octavia octave fuzz with an added tone control.  There is an order switch to determine if you want the Octave fuzz to go before the SI fuzz or the other way around.  This all goes into a Univibe circuit.  Taking a little bit from the Harbinger 2 and a little bit from the RG Keen UVICS, I modified the vibe to use a single pot for the speed control.  Using a single pot, I have it wired to a switched jack so I can use an expression pedal to control the speed of the vibe.  Its pretty cool!  The end of the chain is a Marshall Amp circuit, pretty similar to the Ramble Drive, with a switch to go from +9V or +18V and a switch to go between 1987, 1959 and JTM modes.

All in all, I am really happy with how this turned out.  For having 18 board mounted parts going into an enclosure, it went together about as well as one could expect!  Using the stacked boards, I am about maxed out on height.  It might be a little more comfortable to put everything in a 1590D (the taller version), but it works just fine in this box.  It sounds really cool, and (if I could sound even 1% like Hendrix) would make for a great grab-and-go or inspired by board.  Unfortunately for me, since this one worked out, I'm on my way to designing a few more "inspired-by" boxes like this.  I already have a Page box designed and ready to go, and am about halfway through doing two separate Gilmour inspired boxes.

Build Reports / Schu-Tone Six Shooter
September 08, 2022, 02:31:53 PM
I was at StompboxParts the other week, just shooting the shit as I usually do when I pick up my parts, and the guys always pick on me a little bit for being crazy with my 1590A enclosures (which I agree with).  They were daring me (challenging me?  encouraging me?) to see what I could do with a 1032L (the 10" wide looper) enclosure.  The crazy look started in my eyes and the hamster in my head got on his wheel as I ask for a tape measure to do some quick measuring.  Taking a look, I figured I could fit 6 one-knob circuits in there no problem.

So here is what I came up with.  It is the Six-Shooter, six one-knob circuits in the box.  The circuits are:  The Swine Treble Booster (GE Rangemaster), Muscle Overdrive (Dumble-like), Spook Distortion (BMP-like), Rock Bottom Phaser (Small Stone), Spectator Chorus (Micro-Chorus) and Jormungandr Delay (One-knob delay).  They all fit in no problem and now I have a pretty cool little grab and go pedalboard (if I had anywhere to grab and go with it  :o).

The second relay in the Cavalier is for the Stereo output switching.
Ah, okay. Are both relays controlled by the same pin on the MC?

That is correct!
