Looks great inside and out. I really like the rotary switch in place of the toggle.

Hawt!

Where did you find a bezel for that 10mm LED?

Thriller uses a drum machine, and they had access to Porcaro.

For me, it's always been the bass that drives Thriller. The push and pull of the baseline against the perfectly metrinomic drums creates the rhythmic tension. Parcaro would have made it groove for sure, but in a different way. At the risk of over thinking it, the drum machine is kind of like the zombie horde; inhuman and relentless.

Please... one favor though. Bend up that shorting bar on the stomp. One half millimeter twist on that stomp switch and it all gets shorted to the case  :-[

 ;D The angle and the lighting make it look much closer than it is. I promise it's a solid 2mm away from the enclosure! If it would make you feel better, I could stick some electrical tape between the two.

Looks good. Is that the TS9 circuit?

I didn't have a particular Tube Screamer in mind. I think all variants (Ibanez and Mazon made ones, anyway) are symmetrical soft clipping. I went for asymmetrical because it seemed to tame the highs in a way the simple tone shaping couldn't.

that's very cool, would love to hear an audio demo with your rig.

If I can get a Sound Cloud account together I'll post something here.

Build Reports / Minimalist Tube Screamer
« on: January 06, 2021, 02:25:52 PM »
I tried to reduce the venerable circuit down to it's essence: a mid-range focused overdrive. The graphics are also minimalist.  :P



I've been really enjoying single knob gain circuits because they force me to pay more attention to my playing and to work the knobs on the guitar. That said, this circuit has a little more gain and a little more treble than I'd normally use in a Tube Screamer because those can be tamed with the guitar volume and tone respectively.



This design is not as mid-focused as an original TS. The bass is rolled off below 312Hz and the treble is rolled off above 3.1kHz. Additional filtering after clipping rolls the highs off above 4.8kHz, just enough to tame some harshness.I used a linear taper pot so that the "boost" portion takes up most of the sweep. There is only a modest amount of gain on tap compared to a lot of boosts, but it's still enough to push an amp. It does what a TS does: tightens things up and adds some grit.



Lastly, here's the vero layout in case anyone else wants to play around with this.

That enclosure finish is top shelf! Really nice work.

I've been refining my decal technique. I bought the enclosure already powder coated from Tayda. I roughed it up with a 0000 pad, put down a layer of clear coat, put down the decal after misting the enclosure with a water/vinegar solution,  then put a few more layers of clear coat on top of that. I've been getting good results with this process. As long as I don't fuss with the decal too much when placing it, I don't get bubbles or silvering.

Did anyone else think there were no controls on it, at first? I'm diggin' the orange.

I went with orange because I didn't have any orange pedals yet.

Nice.  Huh, I’ll have to check out that schematic.  Seems like a low part count build. 

It is pretty simple. Here's the schematic I worked from:



And here's the vero layout I came up with:

Build Reports / Push Me Pull You

This is a vero realization of Tim Escobedo's Push Me Pull You. The nice thing about this circuit over other analog octave up designs is that it doesn't require closely matched diodes or a transformer—just two transistors with similar gain characteristics. This circuit responds similarly to other analog octave circuits (best on the neck pickup around the 12th fret), but with more flexibility than something like a green ringer. Cowboy chords at low gain settings creating really interesting intermodulation distortion which you can't get anywhere else. Even at minimum gain, there is still a modest boost on tap (maybe 6dB). Higher gain settings offer plenty of gain to push an amp or another pedal.



The graphics are water slide under clear coat.



Potentiometer lugs are grounded through the chassis. Laying down the electrolytic capacitors allows for enough clearance even in a 1590A enclusure.

Haven't watched the demo yet, but it's on my "watch later" list. Love the paint job! Is there a story behind the angry triceratops?

« on: November 20, 2020, 11:17:11 AM »
I use a Fender Excelsior with an Emminence Big Ben installed. I know that's not a common choice. I think it works well with pedals because the preamp has a very simple tone stack and the speaker isn't very peaky. All the frequencies you'd want are there.

General Questions / Re: Pork Barrel ticking/clicking
« on: November 19, 2020, 10:44:03 AM »
Since this will require some changes on the board, I would try improving the lead dress first. Cut the wires as short as possible.
A large capacitor between 9v and gnd could help reducing the voltage drop that causes the tick.

This is definitely worth trying. I had a Pork Barrel that ticked. I routed the send and return wires along the edge of the enclosure instead of under the PCB and the ticking was cured.

Love the clean esthetic! What color/finish is that on the enclosure?

Do you think you'll CNC again or go back to chemicals for etching PCBs?

Digging Joshua Lee Turner lately. The music is easy to listen to, but full of little intricacies that keep me coming back to listen again.

I've been happy with my Behringer UMC404HD. Unlike a lot of interfaces on the market, it's actually USB standards compliant. Plug it in and it works. No need for drivers.

Those look a lot like Squarplug SPS5 or SPS4 to me. The squareplugs are soldered connections.
