Title: Series switch confusion
Post by: storyboardist on May 12, 2022, 05:47:53 PM
So I've been trying to figure out the switching scheme that was used on the original Way Huge Camel Toe. The CT is a 2-in-1 (Red Llama + Green Rhino), but the bypass switching is a little squirrelly. One footswitch turns it on with the other selecting between the two circuits, similar to the EQD Grey Channel. However, there's a toggle switch labeled "series" that makes it so the first footswitch turns on the Rhino side, with the second footswitch turning on/off the Llama side (Rhino into Llama). The new version does this switching electronically, but the original from the late 90s did it with 2, 3PDTs, a DPDT toggle, and a DPDT relay. Here's some gut shots:

Here's the schematic I worked up, but I haven't been able to get it to work. Was hoping a second+ pair of eyes over it might help. All the switches makes my head hurt after about 3 minutes. lol

If anyone has any input or is just a wizard at switching, any input would be appreciated.

I've been wondering this too, I have a PCB of the gray channel.

So, the channel switching stomp has input a and input b. Lugs 1 and 3 on your site. If you put a switch to connect those to together. That would work, but, if I'm thinking right, that would be parallel and not series though, wouldn't it? Hmmm

This will work, although I don't know if it's the same as the original.  It does work the same.   The "Series" toggle puts Side 1 > Side 2 and converts the Side Select switch to a Side 2 Active/Bypass switch.

Thanks so much! Much easier with 3, 3PDTS than the extra relay non-sense. Appreciate it!
