Knocked this up today from Lawnchair's Schematic. Unverified as yet, any eyes cast over would be greatfully received.

The mu-amp has been used as a building block for a lot of pedal designs.

In terms of gain stages I like the sound of Jfets second to tubes. The mu-amp arrangement has a BIG benefit in terms of building on scale, first a jfet is cheaper than a trim pot and you don't have to spend extra time tuning from the line and fielding down the road in CS. So it is a great building block for sure.

The DLS was an extension of the Habanero Fetish I made sometime around 2000. Like an idiot I was experimenting with patina of copper I made a copper faceplate for the Fetish and stuck the entire pedal guts and all in the bucket with ammonia. Needless to say the pedal died.

what was the second switch for on the "Hanabero Fetish"?

(Hanabero Fetish, Chili Picoso... you do have a fetish for peppers )

I hear Danelectro is developing a pedal with fringe.

Second switch switched out the second gain stage. The story goes about the habanero is I grew some when I was living in Kentucky, they grow GREAT there better than in Oregon. I had so many I didn't know what to do with them. I cut a few up and made a salsa or something I don't remember exactly. An hour later I went to take a leak and suddenly my junk began to burn to all hell. It really hurt bad and seemed to spread. My girlfriend at the time brought me a glass of milk, I jumped in the bathtub, and tossed the milk on the burning. The pain went away but damn those peppers were hot!

Many thanks ShortScaleMike !

hahaha, ever since, every time you see a pepper you get strangely aroused...

... And the moral of the story is, always wear gloves when playing with your habanero.

Or have milk readily available.

Great Job WKH!

Most notably the BSIAB. I haven't heard it implemented in such a great-sounding way before this one, though. All previous incarnations left me feeling like I had chewed aluminum foil.

The OKKO Diablo is a really good-sounding pedal that has similarities to the BSIAB.

Sorry for the confusion, I thought Lawnchair had done it. Thanks to you both.

Aside from the transistors all being drawn the wrong way round which I will fix tomorrow, my layout is verfied and working. I built it this evening

[RnFR]

hey guys-

whitekeyhole was nice enough to send me his eagle files for the dls, so i thought i would clean up his schem a bit. here's what i got-

[dap9]

Awesome work everyone! I'm having a hell of a time "seeing" the wiring of the Rock/Rawk switch. Can someone draw it out? I get the rest of the schematic, but can't get the image of how that DPDT is wired. thanks

[RnFR]

the way i'm thinking it goes is that sw1a on my schematic is one half of the dpdt, and sw1b is the other. don't quote me on that though.

That is nearly correct, they're labelled SW1 and SW2 on my layout with P being the Pole and A/B either side.

From messing with the veroboard I made up yesterday when I had the poles seperate so I could do the "correct" and different combinations, SW2 affects the overall gain and voicing from the oldschool to the newschool whereas the SW1 change tightens up the bass response in the higher gain mode.

Anyway: Verified veroboard layout. Will fit into a BB Hammond Case with ease, not so a Hammond B, I would have to halve the width and make a taller layout.

An hour later I went to take a leak and suddenly my junk began to burn to all hell. It really hurt bad and seemed to spread. My girlfriend at the time brought me a glass of milk, I jumped in the bathtub, and tossed the milk on the burning. The pain went away but damn those peppers were hot!

Oh wow, I had EXACTLY the same thing happen to me once after just handling some standard black pepper. I can only imagine how bad it would be with Habaneros!
And one time, I was cutting up those thin little red Chilies and got it first in one eye, and then both eyes... I stuck my face in the sink for about 10 minutes.

... and then there was the incident with the Icy Hot...

The hotness of peppers and chilis comes from an etheric oil called capsaicin (http://en.wikipedia.org/wiki/Capsaicin). It is not dilutable in water/hydrophobic. Therefore on any contact with sensitive bodyparts use milk, wheatoil, butter etc. to bind the stuff.
