I thought I'd put this up a while ago but apparently I didn't. True story.

A friend asked me to pad the XLR output on his and it would have been rude not to trace it out. This is the original one, and an early one at that (lots of mods/hacks on the PCB to make it functional). The only bit I'm not 100% on is the output buffer, it used a 4066 for switching in a way I haven't seen before and I only had it for an evening so I had to give it back. The caps were SMT, measured in circuit and removed...

Lookie what I found..... :twisted:

Hey all,

I'm looking for a schematic (or even better: a vero layout) of the Earthquaker Devices Palisades overdrive. This thing is a PGS exclusive, which is pretty annoying, especially for us outside the US.

There is a gutshot in the pgs demo, but I doubt it will be useful... (gutshot at 1:45 --> )

Any help is appreciated :thumbsup

Hi! I have an interesting device. I started working on drawing his schematic. Everything is clear. Give me time and I'll draw a diagram. If someone already has a scheme, we will cooperate. :horsey:

Someone sent me a PCB layout and some pics of this through my blog and this is what I've come up with from it. Obviously open to corrections for silly mistakes because I'm not the resident tracer. Nothing much to see here I suppose, but Sean obviously has a stockpile of 2N3906's that he wants to get rid of.

Hi,

today I got the chance to crack on up. Better build quality than the first DBA stuff but still... hmmmm kindly spoken in great need of improvement (as my english :D). The routing of this thing sucks (why double sided? it probably would fit on a smaller pcb one sided!!!) as it does for me soundwise too. Nearly no usable sounds on a sensible volume setting. Despite that it sounds pretty farty imho - and don't get me wrong! - I realy dig some of the Devi Ever stuff soundwise, but this gadget...

Hello good people!

I borrowed a Nocturne Brain Seltzer from a friend a while ago, and took a look at the guts, but don´t tell him. :blackeye
No magical snake oil inside :mrgreen: Altough a pretty nice sounding pedal!
I tried to find out some values, maybe you wanna help me to make a vero layout?

pf fan found this pictures of the COB:

We all know that it is an EchoPlex pre (I don't know wich one). But whats the deal with the 3 ways EQ switch?
