Is there a schem for this anywhere? Has onyone built one - lately? I heard some clips that sounded interesting. I also found some archived posts referencing a site for Joe, but they are no longer active.
TIA!

I've got a copy somewhere, pm me your mail and i'll send you one.
bump!
You can find the Skyripper and other NVN schems here:

Thanks all,
The skyripper seems like a really cool effect but the schem looks a bit "serious" for me. I'm going to build 1 or 2 more pedals before I try a Skyripper. I would be interested to hear anyone else's experience if they try it before me.
Here's the schematic:

I have made close to different (and good sounding) fuzzes and, to my ear, the Skyripper is my favorite. It has so many different sounds in it. I'm still discovering new sounds after many hours of freakin' with it. If you end up doing it eventually, pay close attention to RG Keen's germanium transistor testing procedures and get the right one that he suggests. I still have yet to put it in a skillet, though.
The Skyripper is an exellent pedal indeed.
I am rebuilding it right now with leds for the main functions(fuzz and trebleboost)and the other functions footswitchable.
The interaction with ones playing/guitar volume is sooo cool :D
Greetings,Ed
It's a thoughtful design and I'd like to make one some day. For those put off by the multiple trimpots, switches and jacks, do not feel obliged to incorporate EVERY option shown. They may all do something useful, but that doesn't mean you need them all at once to have fun with it. Besides, you can only have fun with it if you have a working one in your hands, and that can only happen if you build it (or pay Joe to), so whatever puts a working one in your hands is what you need to consider.
For instance, the Bias control between battery and ground. Scrap it. The switchable (S4) trimpot on the last transistor. Scrap it and just wire the one 10k trimpot directly to the 390R resistor. The expression loop, including the two jacks, NKT275 used as a diode, and "Ripper" pot. Scrap it and just have a 100k resistor from Q3 to Q4 like the average Fuzz Face.
Will this make it less wild and wonderful? Sure. Will it leave you plenty to mess around with? You betcha. Can these things be added in later? Yes, just leave enough room on your perfboard.
Hi Mark, hi everybody!
I have to respectfully disagree, if you don't incorporate all of the features it is better to just build a fuzz face with a lot of biasing mods etc.
The cumulative effect of all of the features is greater than the sum of the parts due to the subtle interaction of all the biasing elements, feedback and treble boosting/gain situation, etc. In my opinion the pedal is too much work to build if it does not got the full skyrip tones.
one of the main points is that when it is really 'ripping there is a fight going on between upper and lower harmonics that causes the sound to swirl in a very reactive ( and musical) way.
any ge trans will work as a diode in place of the nkt 275. standard ge diodes did not sound quite as good to me tho.
pay close attention to the biasing instructions. they are quite specific for the real skyrip tones.
Good luck and feel free to email me at joegagan@hotmail.com
Wa-hey!
Welcome back!

Hello Joe - once you`re here,
could you please enlighten us on the question
of the Bronto-volumepot here:
http://diystompboxes.com/sboxforum/viewtopic.php?t=19966
Thank you very much.
To paraphrase that old Luther (or was it James?) Ingram soul nugget "If luring you is wrong, I don't wanna be right".
I guess my point was not that it was 'just as good and simply lacking a few bells and whistles" in the diminished form but that it could look intriguing and at the same time intimidating to some because of all the controls involved. For the intimidated, it could be made more inviting by initially omitting *some* of the add-ons, and completing them at a later time. A bit like buying a home with a carport because you can't afford one with a true garage, and adding the garage in later when you save up and have the time.
Actually, now that I think of it, for those designs (and not just NVN) for which there is no current layout (implying an obligatory perf-build or own-design layout), or for which there is a substantial parts/cost outlay, it might be helpful to some builders to divvy it up into "now" and "later" parts. The "wife" you'd like to get to know first, before you have "kids". :wink: Certainly the brunt of projects/circuits discussed in this forum tend to be fairly simple fuzzes, so that sort of division doesn't often apply, but once in a while something comes along that really needs to be broken down into chapters to be a little more inviting.
And hi Joe. The offer for billeting during Ottawa Bluesfest still stands.
Mark
hello~
i know it's a longshot with all the trimmers and all.. but does anyone have a pcb layout for the skyripper..?
Mark: it was Luther I;
one of, if not the best Wah songs (next to Bread`s: Guitar Man).
