So it's a complicated circuit, let's document this shit. I had more time than I thought tonight (meaning I soldered for 4 hours)














After testing found an IC wasn't seated ok and that a jumper is going to the wrong track, just needs a cut and strap, no bother. Will resume after Doogfest

lol klon.

im interested to see how it sonds.

I breadboarded it before I started to build it. It sounds good.

$400 good with an 18 month waiting list? Nah.

Whatever I end up charging for it (<£100/$200)? Yeah.

I built it because I wanted to know if I could, plus some people expressed an interest in me cloning it.

right on man.

its cool to see you doing these epic builds. photo progress for the win.

what type of box are you putting it in? you should paint it green. the color of the money the guy who builds the klon whipes his ass with. cuz hes a fucking money grubbing bastard.

1590BB I think it's called, the one up from the smallest Hammond Box. I have it drilled already:





The other box is Mezz's Green Ringer.
I offset the knobs and put the DC jack and jacks between then for maximum space for the large board, since I don't have PCB facilities.

looks grood. i mean good. great and good.

do you have teh knobs picked out?

oh god who the fuck cares. im just excited for sonds.

haha... Teen Girl Squad reference. Nicely done.

I'm boring. I use Mustang knobs for all my builds. They're all in teh Whore House thread.

mustang knobs ftw?

i was gonna say you should get some of those pointies. but if youve got teh mustangs, use teh mustangs.

teen girl squad for the win, im sure.

The rest of you are all cocks.

Good work Mike - glad you are building one of these, will be interested to see what such a rip off pedal sounds like!

Resize your fucking pics and I might leave a commen- AH FUCK

Kudos, sir. I have no idea how that compares to something like a TubeScweemer circuitwise, but it sure looks complicated for an OD.

They should automatically resize? and Photobucket has a go at them when it uploads them I think.

Eitherway - Suck My Balls.

Hopefully I'll get it debugged and working shortly after Doogfest.

It's got an input buffer, and an overdrive stage. the input buffer is always in circuit, the footswitch just switches the output from post overdrive to post input buffer only, it's interesting. People rave about teh input buffer, so rather than True Bypass it, I'm making a complete copy. It's a very unique design, it's not a tube screamer. The dual gang Gain pot actually controls boost and grit at the same time, it's pretty much Black Art.

The third chip is this Panasonic thing which is used as a charge pump for the final op-amp.

It's crazy.

Your productivity amazes me. I spent a few minutes scoping the HT waveforms on the TSL100 and measuring cap diameters and spent the rest of the evening playing Rock Band.

Using turned pin sockets for board connections - Hmm, interesting idea. Looking good!

Thanks man. it's amazing what the lack of a social life, money, and also latent hyperactivity will do for your productivity. Plus I get all excited about projects and throw myself into them at the detriment of everything else in my life. I have an oscilloscope I'm borrowing from a friend now so it won't be long before I'm making trems, and other modulation pedals I imagine.

The pin sockets is something I used on Hurb's Foxx Tone Machine build, I had two connections that were moored in the middle of the board to the Octave switch so I used the sockets to plug those last two wires in. This layout is similar, there are plenty of moored connections, I'll probably solder to track all the outside ones and the ones that are easily relocatable but the hard to reach ones will stay at sockets, they're very sturdy and it;s a good system for testing.

I found a cap the wrong way round which I'll also fix after Doogfest, I'm pretty sure it'll just wake up then.

That cap was the right way it turned out. I fixed the jumper wire and also found a tricky cut trace that needed doing which I didn't see, so I did that now I have Overdrive.

It sounds muffled at low treble settings (I guess because I'm testing with a log pot instead of a lin) and it actually goes splatty at max gain but overall it's there. I think when I solder the flying leads instead it'll sound fine. So I'm pretty close to building it into a case which is awesome.

would make an awesome T-shirt design

Yeah, it's not bad is it. Not my design unfortunately. This one is too complicated for me to do anything but follow instructions, but even that is causing difficulty. This is a beast of a circuit.

Remember this?

I trashed the old board and started again with a better layout. Built it on Friday night, plugged it in today and BAM. Works first time and sounds GEWD.







I maded a demo video so you guys can hear what this elusive pedal really sounds like. It's uploading now.

It sounds nice, not $400 nice.

Ugh, thats so much money, at that price you could probably buy an amp wth a decent overdrive rather than the pedal.
