Build Reports / Vaguely Russian Themed Firebomb
« on: December 09, 2011, 09:29:36 PM »
I finally got around to building the firebomb I bought last year.  Dead simple build.  Works like a champ.

General Questions / Dinky Drive
« on: October 24, 2011, 08:59:04 AM »
Has anyone out there built the Dinky Drive when it was available?  Or recently, with Haberdasher's PCB service?  I am wondering what people thought of it.  The Rump Roast sounds so good, I was thinking the DD might as well.  Thanks


General Questions / Transistor orientation in LaVache
« on: September 26, 2011, 11:17:37 AM »
In the build diagram, the transistor is not oriented at 9:00 or 3:00, but kind of 11:30ish.   Is there a reason for that?  Is it yet another gap in my stomp box building intelligence?  Thanks.  I appreciate it.


General Questions / La Vache Transistor
« on: August 29, 2011, 08:53:28 AM »
Hello.  I am having trouble getting the 2n3565 for the La Vache.  How horrible would it be to use a 2n5088?  Has anyone subbed the 3565?  And with what results?  I guess I could socket it and see if I can find a 3565 later.  But I was curious if anyone else has tried it.  Thanks

Build Reports / My Zombii
« on: August 08, 2011, 04:39:24 PM »
This is my Zombii project paying homage to "Shaun Of The Dead".  I don't have a gut shot yet because somewhere between the rocking of it and the boxing of it, I lost the LED and the DRIVE pot doesn't seem to do anything.   But it's loud and nasty and I don't know what I'll do with it, but it's fun to wail away with.

Tech Help - Projects Page / Mudbunny Diode Switching
« on: June 02, 2011, 04:05:14 AM »
Hello.  I was wondering about the diode switch idea mentioned in the build doc.  I get the concept but I was wondering how - physically- you accomplish that.  In other words, how do you wire up a switch to choose between two pairs of diodes?  Thanks in advance

Build Reports / Neutrino
« on: May 31, 2011, 08:08:25 AM »
Here is my new neutrino.  It sounds great.  It's a little hummy (especially with single coils) but it's cool.  The white knob was not intentional.  The 3rd black one I got from Mammoth had a stripped set screw so I grabbed the only one I had laying around.  Thanks again to Brian for the great board and all the forum members for answering the endless questions.

General Questions / Project Complexity
« on: April 29, 2011, 04:51:56 PM »
I was wondering what determined a "Cowboy" project versus a "Noob" one.  Is there a part amount threshold that gets breached or is it a judgement call based on how it's set up?  Or something else?  And what is that NOOB graphic?  I can't stop looking at it.


Tech Help - Projects Page / T Bagger no distortion
« on: March 30, 2011, 03:00:24 PM »
What does it mean when you turn a distortion on and you get the dry signal?  The volume works and 100% brings it to unity gain, but no effect at all.  I did some initial audio probing without success since the signal is coming through the circuit, just not being "effected" by it.  So I guess my question is how does the unit distort?  Is it the IC or the diode?  And if either or both of those components are dead, can the signal still go through?  Or is it, as I suspect, some other weirdness.  I have burned this unit once already.  Literally, smaoke coming out.  The 4001 diode was toasted and replaced.  Anyway, where would you start looking? 


Build Reports / Your Moment Of Zen
« on: March 26, 2011, 08:05:28 PM »

Here is my just completed Serendipity (Zen Drive).  It sounds good.  I figure there's some tweaking to do, but so far so good.  The picture has a large glare on it

And here are the guts.  Sorry about the blurry picture.  I can't seem to get it right

Thanks to everyone who answers my seemingly endless questions!


Build Reports / Electronics At Work (Rump Roast)
« on: March 22, 2011, 06:34:14 PM »
This is my Rump Roast.  I use it as a dirty boost, mostly.  It's like having a dirty channel on my Blues Jr.  Had a mishap with the graphic, and the labels are a little off - I have that problem with printing from Photoshop -  but I'll re-do it at some point.  Thanks to the 1958 IBM advertising department for the graphic.  Thanks to Brian for another great project.

General Questions / Cherrybomb Question
« on: March 20, 2011, 08:02:10 AM »
Is the Cherrybomb a mostly direct clone of a Colorsound Overdriver?  The reason I ask is that I heard one of the ThroBack Overdrive Boost pedals which is also a derivative of the CSOD and it sounded really nice.  Seemed to have a lot of flexibility as far as it's range of cool tones.  I was wondering if anyone knew if the ThroBack was significantly different circuit-wise than the original Colorsound and could those mods be incorporated into a DIY pedal?


Tech Help - Projects Page / Smoking T-Bagger

I'm guessing it's a bad thing when smoke comes out of your box when you are testing voltages with a DMM, right?

General Questions / Using different transistors
« on: February 25, 2011, 11:55:14 PM »
Just a general question.  If you are building a Big Muff type circuit, as an example, and it calls for 2N5088's, can you mix and match them with something similar like 5089's or do you have to decide on one and make them all the same?



General Questions / Rump Roast Treble
« on: February 23, 2011, 03:25:20 PM »
I love my new Rump Roast but it's got gobs of high end.  Is there a place I should start messing about with different values?  I am still learning so it would be a lot stabbing in the dark.  But it's a great boost / overdrive (I built the hybrid) excepting the treble bit.  Thanks
