I'm assuming this is out of the question... but if it's not... rainbows :o 8)

I'm pretty certain its DSP based mate so its a no-go I'm afraid.
Awesome pedal though.

Even if it wasn't, unicorn ejaculate is unobtaniom. I heard EHX bought it all up in the 5000s BC.
This is the most ridiculous thing I've maybe ever heard in a production pedal. Finally a perfect mate for my fuzz factory. Together they'd make the most perfectly matched useless duo of all time! Like two Aqua Mans.
What I'm trying to say is that I want one way too much!
The JetCity video demo on YouTube includes a lingering gut shot which allows just about all components to be clearly identified - the pot values can even be seen clearly marked on the PCB.
The heart (or brain) of the Machine is the FV-1 chip produced by Spin Semiconductors. Looking at the Spin website, I note that the FV-1 is "a complete reverb solution in a single IC" (!)
There are 8 programs built into internal ROM and the facility to have an additional 8 user-programs stored in an external EPROM.
As far as I can see (but I'll stamd corrected by anyone with keener eyes or more knowledge than me) there does not apear to be an EPROM in the Rainbow Machine - the other chips look to be two 074s and a 4049.
The FV-1 looks like an interesting chip, ripe for DIY development - don't know what the price is, though.
it would be a really cool project to emulate or try to replicate

THANK YOU!
I suspected this was the case since the pitch shifting is the same exact range as the FV-1 spec sheet.
There may very well be a madbean FV-1 project of some sort on the horizon. ;)

I don't see one either. But we can only see the top of the board. There well may be an SMD EEPROM on the bottom. It is also possible to have Spin put your programs on the internal ROM, but the minimum order for that is a couple thousand units. Not sure if EQD is *that* big yet or not. It's certainly possible, I suppose.
I also don't see a crystal oscillator in that image, but I know it has to be there somewhere. ;)
I have one... Possibly the most pointless thing in the world ever. But made of purest awesome.

There are actually some useable tones in there if you are much more subtle with it, this demo shows it's range better: http://www.youtube.com/watch?v=NNerqcvR3Rs
But what's the fun in that?
The FV-1 chip sounds like an interesting little thing. Has anyone tried anything with it on a DIY level? I imagine that it'd be usable out of the box without having to program it, with how the PDF talks about how easy it is to integrate into an analog circuit.

Banzai sells the FV-1 for E13,45 , which is about $17,50? Probably available from other, cheaper sources as well, so let the ridiculoussness begin!

Hey Juan, would you post this photos over at FSB:
http://freestompboxes.org/viewtopic.php?f=7&t=17733
Just upload them directly, please. ;D
Other than the FV-1 I see a 074 and a 4049. What's the last chip?
Jacob
This would be the most coolest thing to fool around with but the most useless for my playing situation. Bring it on!!!

Done ;)
this picked up really quick. hopefully we're all going to be farting ridiculous sounds out of our amps soon 8)
I've just posted some high res pics of both the front and rear of the board to FSB if you want a closer look.
EQD is just so awesome anyway, totally ripe for a DIY outing! I've got their Disaster Transport and it's about as close as you can get to a DMM in a digital package.
