There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

you think maybe this is a green ringer with volume and clean blend functions added? hmmm...

Information
It´s more a mix of a Fender blender input stage (similar can be found in the foxx Tone-Machine and Univox Uni-Fuzz) followed by a foxx Tone-Machine Octave/Distortion-engine. Have a look at these schematics.

where are the schematics? I've been digging around for them for a while and can't find them anywhere...

Learn how to use the search function - if you type in "Fender" and "Blender" you will get this:puppiesonacid wrote:where are the schematics? I've been digging around for them for a while and can't find them anywhere...

analoguru you have a PM, also if anyone knows where I can find an prescription electroincs schematic for the COB let me know. I'd like to compare them with the blender.
Thanks.
Thanks.

I'd like to add pictures of mine. It's an earlier version but appears identical to the model submitted by AG.
Those of you with an art program capable of creating "layer" images of varying opacity should be able to convert these two into a
usable schematic diagram.
I drew up a schematic years ago that I'll submit for reference to parts values at best.
The picture host has lopped off the right hand side of these pics. At least on these included pics. Bummer. Here's the links to the
picture files. I hope it helps.

Just "right click" on your mouse and select "view image"...you'll see the tracks.

no, the bottom left corner of the pcb tracks is cut off in the picture.

using this pic the AG linked you should be able to figure it out.puppiesonacid wrote:no, the bottom left corner of the pcb tracks is cut off in the picture.

it "looks" at a glance like the traces end there, so whats off the pic are just offboard connections...but i didnt look closely or analyze it.

I built this using what I assume is Torchys vero and can't get it to work. There is a direct guitar signal without power, but when power is hooked up, just noise.
Has anyone else built it?
