New vero layout: The Skyripper

[cathexis]

Hi!

There's a new veroboard layout in my gallery, today: the Skyripper intermod reactionary guitar unit! By Joe Gagan, I haven't built any of his other designs, but this one alone makes him a hero in my book! It's a long time since I had so much fun with a guitar pedal. The standard fuzz and treble boost sounds are all there, only a little bit more beautiful than I've ever heard them. And the crazy stuff, the NOISE possibilities! You need this pedal! If a vero layout makes more people build this pedal, I'm happy about that. Please tell me if it's OK to share this, I've asked before without getting an answer, and will remove it immediately if necessary.
If you build this, you'll need a schematic (this is based on v3). You'll find that at ampage.org. There may be small mistakes in my layout, maybe a pot wiring that needs reversing or something like that. Please tell me if you find anything wrong. I built it, and it's working.
No sound clip this time, I couldn't do this pedal justice. Check ampage.org and www.tungngruv.com for lots of good ones. I put a picture of mine in my pedal pics album - anyone that worked in a factory in Sweden in the fifties will recognise the enclosure .
Now build it. Don't skip the effects loop!

You have some great stuff in your gallery. Once I get a little more experience, I'lll have to revisit it 

Very nice.

[John Lyons]

Cool!
I like the table top version


Dare to show us the guts!
I have an edited version of one of Joe's noise chaotic noise soundclips.
I'll have to post it.

Nice looking boxes in your gallery too!

Here are some soundclips of the Sky Ripper in action.

Gut shots?? Sure!!



                       

Once the infatuation abates slightly, I'll play barber and snip away a half mile of superfluous wire. I'm not there yet .

Thank you for your kind comments, John! Getting cred for stompbox looks from you is like having Tom Verlaine AND Richard Lloyd come up to you after a gig saying they agree on liking your guitar playing! (Insert your own guitar god, if you're not a Television fan). You've done lots of beautiful work. I could kill a snake just to copy you

Yeah, the SR is hard to get done cleanly,so many off board connections.
I have still not tried it with the loop...I need to build another one.
By the snake reference I take it you've seen my site

Here's that soundclip Joe Gagan recorded, I just edited it down from the original 13MB (!) to 2MB
Let me know if there is any problem with the file...dial up service here. 

Happy rippin'

My favourite box is Tim Escobedo'd Too Many Knobs, T.M.K, and the sky ripper reminded me of this so I looked into it. The first thing I did was redraw the schematic to make it easier to see the connections.

Once that was done I noticed alot of the connections were between pots and switches which reminded me of point to point wiring on tube amps so I drew that up trying to get as many of the cinnections off a potential PCB.

And, of course, once one gets to this type of thinking, tube amps, the next idea is to set the discretes up on something like tag board, or, I had it before, um, what was it, it's where the resistors and caps are soldered on a board accross the width in rows with standoffs or pins running longditudinally on each edge. Whatever, but down in the corner of the above drawing you'll see Q1 set up on that fibreglass board with all the legs of bits going to PCB pins.

I think this build is very akin to tube style building so why not build it as if it was hand made in the mid sixties.
Oh, and I so found the absolutely right container yesterday to put it in.

Neat drawings Sean!
Nice to see some thinking on paper.
With some many off board connections it help to draw it out and think about it in different ways.

Thanks John, though I should be doing your stuff... I did it again with a bit more finesse.

[Ben N]

Neat (pun intended)! That has a cool sort of R. Crumb feel to it.

[John Lyons]

That's great Sean! Love it.

Some corrections though:
The Vol pot is 500K-A
The Buffer is 1M-B (it's a panner/mixer)
Drive/treble boost is 10K-B
Pregain probably should be 250K-A

Looks nice to see a drawing of a layout like that!

I still owe you the theremin pics too

Bumping in case someone missed Sean's drawings, and to announce the update of my gallery with a Skyripper soundclip. Check out the octave down bit at the end - cool, huh?
