Devi Ever Improbability Drive

[vincentstarkiller]

Firstly, thank you for all the layouts posted, especially the Blueberry bass overdrive which has been my favourite build so far!!

Anyone fancy a crack at this? Don't see why it shouldn't fit into a 1590BB but I am having no joy with doing a layout myself. My guitarist has been bugging me to build it for ages and sent me the schematic that Devi posted ages ago.

Layout here: http://s17.postimage.org/oauz6qxe5/Improbability_Drive.png

Thanks!

Yes I'll add this one to the list.  Stock up on your 3M3 resistors in the meantime :)

Cheers!

Mega bump!
First time poster, long time lurker.
It would be so cool if someone drew up a vero for this, it's seems to be a really interesting circuit.

Thanks for a great site
Cheers
Speedy.

i've been meaning to make a layout for this for like 3 years, so i did one today.

by no means verified:

Cool!!! I'll give it a shot after work.

[Silver Blues]

Whoa, this is funky

[adapt]

just realized there's supposed to be a jumper from (O,K) to (O,M). i'd fix it and edit my post but i'm at work

I built it today and it defintely not sound like the demos, Quite low output, farty and bommy low gain fuzz. Switches don't do much and the the pots acts like volume and/or blend controls. I guess I have to tweak and troubleshoot this one to see if I can get any usable sounds out of it.

Once again thanks for the layout!

Cheers

be sure to check the transistor layouts vs the schematic. there was some ambiguity there.

Had a quick look and I think there may be a mistake:
Q5 should be connected to Q3-Q4 Collector and not to the Emitter.

I took a look and I'm pretty sure you're right. It looks like Q5 is connected to the collector of Q3 & Q4.

There is a 30n cap from I-2 to ground missing.
2N3391 has a BCE pinout.
If you use that transistor you need to bend the Collector and Base legs.

hopefully IvIark will do this one soon since i'd really like to build one.

I found this in my archive -- no idea of its source or if it's verified, but I always had it earmarked as one I wanted to build.

I've uploaded a layout in Contributions.
