Let's see your finished DIY projects!

Looks awesome, where'd you get the Sonic Titan PCB?

Thanks. I want to put a label across it but don't have a printer. Got a handful of the boards from this guy Adam who no longer posts here. He made a run of them a while back, and this was the last one I had so I thought I better make it cool. I actually put that pedal together MONTHS ago but could never get the meathead working properly. Rebuilt it last week and here it is.

Hey laowiz, how'd you get the writing on there? Looks screened.

It's etched. I never get clean etches because I always do it for too long. But it works great for this one. Just scrubbed ith a brush and then cleared it...

Damn, looks so cool, perfect for that circuit! I'm gonna build one soon, but it won't look nearly that badass.

Holy dick tits, that thing is gorgeous...

What is it?

What is it?

Chris Carter’s original Gristleizer units were based around the Roy Gwinn ‘GEP’ design published in Practical Electronic and sold in kit form (just the PCB & components) by Phonosonics in the UK in 1977.

Nice sunny day here in rural Warwickshire, so I thought why not spend it indoors building a Superfly. This one's got a 'Brake' in place of the master volume - takes the B+ down from 190v to 110v.

Your tiny amps are so cool! I'd like to get one some day.

I think I started a gravel background fad

I'm kinda jealous that you know how to work with tubes and I dont. also, always impressed with how clean and professional your soldering looks. like your use of bus wire and rainbow cables. I gotta order some of that from mouser.

Buffered signal splitter. I highly recommend it

[McSpunckle]

Judging by the resistors, imma say... JFET buffers?

You know it. I had pulled them out to trim the leads down.

Here's another I finished up today. It's like the electra but with more gain, tons of volume. Re-used the walco enclosure from a previous project.

Before attaching the toggle

Nothing finished to show, but I'm hacking on my fuzz face viewtopic.php?f=151&t=3277&start=705#p237057 to adjust the value of the gain/fuzz pot. I used a 5K linear pot because I had one on hand, but all the circuits call for a 1K linear pot. Well, the fuzz only really kicks in during the last 10 degrees of rotation or so. So now I need to test the value of the pot with various values of resistors placed across the two outer terminals. That should, in effect, lower the pot's resistance and bring me closer to 1K. Curious to see what it sounds like in the range of 1.5-2.2K actually, since that should give me more "clean" sound on the first half of the knob.

Edit: Ok, so it isn't wired up to allow the "outer lugs resistor" trick to work, since the circuit has "left" outer lug connected to middle lug and those go to ground -- a variable resistor. Mine doesn't have the 20uF cap going to ground, either, but that's ok. Adding a resistor in series would just increase the resistance, not lower it. So I'll just have to source a 1K linear pot. Dunno why Radioshack doesn't bother to carry these, and I forgot to order one in the last Digikey group buy.

wat

Umm...amount of feedback, output volume, ....mojo volume....momentary awesome pinball button and on/off to control the feedback?

[D-Rainger]

Pinball button is just top! Can you foot-operate?

[eatyourguitar]

I wouldn't use my foot on a plastic button for fear of breaking it but I guess you could. I'd much rather make another one with a momentary foot switch. you are correct that it is a feedback looper. you know my style. left to right its feedback, low pass filter, diode clipping (distortion). its pretty simple, 3 500k pots, 2 0.7v Schottky diodes, a 0.15uf ceramic cap. I have to do some testing to see if it even works right. I just made this up from a guitar tone control and the "black ice" distortion. too many times did pedals make high pitch screaming sounds. the cap sucks treble in both directions. no matter where you put the cap in the circuit, its not gonna let any treble escape cause there are no buffers. same deal with the diodes, they work on the feedback line as well as the output. if it works, its gonna be sweet.

p.s. the switch is for a massive 1uf cap that makes the low pass go down to 60hz ish. no volume control, the tone control will make it quitter though
