Wondering what this mod is for.
About to build an ep as a unity only buffer, and another as an actual boost with master vol.

Anyone have any info on this/ a workalike? Or anything else that is a LFO expression device?

This looks like a really well thought out idea for someone with a complex rig (Eric Johnson, you gotta get one!):

Looks like a pair of buffered effects loops you can pan between or crossfade, with the ability to send the signal to different amps or a mixed output to one amp (or I guess 3 amps). I haven't sat down and tried to figure out the signal routing, but having built a super simple crossfader of my own, this looks much better implemented than a couple buffers and a pot… The price is a...

Picked up one of these on sale. It sounds pretty good, but not $380 good!

Notes:
- As seen in the pic, they've tried to maintain the ~mystery~ by scratching the ICs. I can still make out 08 on U2, and judging by the fact that it's a through-hole device it must be an LM308.
- I can also make out 072C on U3.
- Q1 is a 2N5457.
- The glass diodes are 1N4148s.

I'll be happy to provide more pics and information if there's interest in reversing this!

Does anyone have the gut shots?
I guess it is similar to Dwarfcraft The Great Destroyer, but the controls to add white noise and to promote oscillation may be new.

i had one but the price was high for such a small simple circuit. very mesy perf build. i have pics but I couldn't trace it. sanded tranny's
Would Like a vero layout or even a schematic if anybody has time or has one.

Thanks for anyone's help

So, anyone ever take one of these to bits? As I understand it, it's based on the DM-2. We all know about adding an LFO to a DM-2, and about shorting the delay resistor to get the runaway repeats. If the DM-2 assumption is correct, that gets us most of the way there.

One of the two things that are intriguing to me is the wrecked position of the tape switch, which DMB claims is like modulation gone crazy and compares it to someone tweaking the delay knob. I'm guessing this is something along the...

Anyone took a look in one? I am sure it's something common but the tone is tweeked just perfectly to get that Marshall sound better then any pedal I have ever heard.

Holding out on us? :lol:

Here are the pics I got. I don't have it anymore, but I got most of the IC's and all of the pots (if those are needed outside of the pics).

I had this box on the bench. The Rothwell Switchblade actually sounded nice, although a bit too bassy on the eq for my tase.

The problem with this is that its kind of microphonic, a lot of gain and some supect smd electrolytics, and that its mounted soldered to the 3pdt, amplifying noises on the switch and tapping the box...

I couldnt get the values on the SMD caps, I dont have a capable meter...

Anyone have any info?

Is there one out there? I know it's just a Big Muff but I'm wondering what he did to tighten it up.

Hi I thought I'd start a new topic for this.

This is different from the stock Sola Sound MK II, as well as different from the earlier DAM MK II pedal in the big tall hammond enclosure. There are several different parts values, and different transistors used. I've seen youtube demos of this unit and it sounds really, really great. It's also very expensive. I plan to build one.

Here's the schematic I came up with and the pictures from which I determined the part values. Sinner has a nice layout...

Cleaning up the attic and busy reducing the piles of paper.

I found this pictures of this great phaser:
Got NE5517N inside.

Looks more like Tim Escobedo's Harmonic Jerkulator
