Any DIY pedal builders on TB? Strut your stuff!

Woo! Meat Sphere has arrived!!! The board is huge, but the Hammond 1590DD I have is probably overkill. I'll see what I can find, I'm open to suggestions.

The Obsidius is done. It's a cool little pedal, but lacks something... 'character' might describe it. It seemed to like my passive Jazz bass with the bridge pickup soloed and the blend almost all the way on dry. I compared it to my Darkglass Alpha-Omicron. The Darkglass has a lot more of the 'character' that's missing, brings a heavier sound and more drive.

But overall its OK and I'm glad I built it up. I used a label maker for the labels, which made the dark gray powdercoat look fairly 'meh'. Maybe I'll change it up down the road. If the label maker did white on clear if would have turned out better. I need to get more creative with the colors, graphics, etc....

Thanks for the M16878/4 tutorial @AudioTaper — I may need to do that shielded in/out cabling in the CowGirl, she's a teensy bit ticked off.

As for your Meatsphere... 1590DD — I'd go to town and add a separate stomper for the FX loop, maybe make the Moog-Mod a stomper... lotsa stompers, 4 at least, the outer edges staggered a little. Mod the heck out of it.

MAYBE squeeze in 5 stompers?

[Rant]
It still bugs me that every freq'n clone layout for the Meatball copies the originals craptastic 4 rotaries that dip down into where your toes will be stomping — especially if you add more than just the bypass. Probably different with the 1590DD, you'll have enough room.
There's only one out of the four rotaries that actually needs to be a rotary. I'm going to have to figure out how to do PCB layouts, I just can't bring myself to get any of the existing clone boards.
[/rant] I know I've ranted about it before... Hmmm...



@G.Bisson Have you tried the Laswell Dub-setting yet? I'm really curious about it; I've got one Flunkee in Canada, another on the way to HK... See which I get to build first...



@disssa Great work, as always!
I'll have to have a closer look at this Music Man 120B amp.
What size of enclosure did you use for the pedal?



@cosmicevan — You won't need anybody to mail you anything once you've built it yourself!
To that end —> How's the Fuzz Face build comin'?

The board is huge for what's on it, they could have at least made the resistor hole spacing a standard 0.4".

I'm looking at what additional switches I would want. I definitely want the effects loop to be switchable, maybe have 2 switches for 2 loops (in series) I'll probably keep the rotary switches for the most part. The schematic doesnt show the Up/Down switch, maybe I'll track that down and put that on a stomp. (Something I wanted to do with my Emma Discumbobulator but havent yet)

What else is switchable?
 
I wrapped up the Depot Fuzz (PedalPCB's clone of the Terminal Fuzz) AGAIN!
The expensive Fulltone DP3T stomp switch decided that 12 clicks is enough and died. Luckily, I used one of the breakout boards and changing it was quick and easy. I installed one of those LoveMySwitches soft-click models.

I LOVE this pedal, so far. 9/10, which is pretty lofty as I always have something negative to say about anything.

I used black on clear labels, which really stand out against the silver powdercoat from Tayda. I got a small bubble on the main logo, it's less noticeable in person. The powdercoat scratches was my fault also. Green LED.

I was thinking how to describe the fuzz. Brutal, but still in control.
 
Your FY-2 looks great now.


Re SWITCHABLE
Any controls you'd want two settings for on the Meatball? Wire up two pots (you've got the space!) to a switch or get GuitarPCB's 2-knobJob which makes it much easier (and with a trimmer option for if you just want to max/min one of the settings).

Two loops! That's... crazy-awsome. I just want one loop, but you may have planted a seed...


My plan for a Meatball involves the following:

An additional “Loop” control to attenuate or boost the loop’s return signal
A master clean boost on the final output.
A Bax concentric Bass/Treble dealio.
A Colour knob = resonance.
A "Range" KNOB — GORECAP! Would have to be a Dual-Gang pot, or concentric for even more tweakability 2n2–15n

Jacks: OUT EXP1 EXP2 9v FXR FXS IN
Knobs Top Row: Sensitivity Attack Decay Intensity Colour Blend
Toggles and knobs bottom row: Mode-sw BW-sw Loop Range Boost Moog-Sw Sweep-Sw

Stompers at a bare minimum: FX ON/OFF

Maybe the Moog and Sweep as stompers instead of toggles. Mode is on-on-on IIRC, and Bandwidth is on-off-on, so can't have those as stompers without crippling part of their functionality.



The "2" Hammonds are a bit higher. I needed mor space, because the volume pot is a dual one. It is also a "special" one. On one side it is a A100k, the other side is a C100k. I can´t find any dual pots with this specifications, so I "built" my own one... (after a tip from @johnk_10 )

Yeah, that's why I like them. I almost always need the extra height — or at least, it would make my life easier if I always had the "2" Hammonds.

I've got an Aion PCB, Chroma (Boss SP-1), that will require "building" my own A10k/C10k dual-ganger. Aion has good instructions on how to do it.

What's the synth in your avatar? Those buttons look similar to the ones on my old Arp Omni 2
View attachment 4254089

I wish it was a nice synth! It's a small study/toy organ by Bontempi, it was my first "instrument". It actually has no circuits inside, just a noisy fan to blow on the reeds!
I keep it as furniture now, but I'm still attached to it, gotta love the funky lime green.
Your Arp looks great.

Btw you guys are killing me with all these nice filters (gotta get me some...) Keep em coming

The Arp was sold a few years ago to pay bills. It needed a full recap and had some other issues, but I made $400 on it.
Old school!!

Oh, and get some filters!!

I worked in the factory right when ARP was transitioning to that graphics treatment, it was my first legit MI electronics tech gig.
 
Madbean Fireaxe freebie!
With a hot bass this makes for a nice distortion pedal! Sub switch and baxandall EQ provides enough bass with mild tone tweaking. Lots of dirt-stacking potential with this one. As a clean preamp, it's not so good with bass due to limited headroom. I had to turn down and dial out bass to prevent ugly clipping.
I didn't have a paint plan for this freebie so I just threw all things red at it (fire=red) :rolleyes:.

This pcb uses 16mm pcb-mount pots except "Vol" is a 9mm pot. I used all 16mm solder-lug pots without modifying the drill template. Adapted the "Vol" pot by criss-crossing 22awg solid wires and tucking them under the solder lugs. Bent the solder lugs in tight to the pot and taped them off so they wouldn't contact the enclosure wall.
