McMeat Sweep Question:

[chicago_mike]

Can I use a DPDT or #PDT Footswitch instead of a rotary switch for the Sweep? I cant locally get what I need for that control. And its all wired except for that section.

Looks like a 3pdt switch will do it for you. sw2A, sw2B and sw2C are the centre lugs and sw2A-1, sw2B-1 and sw2C-1 are at one end and sw2A-2, sw2B-2 and sw2C-2 are at the other end.

what is sweep? you mean up/down? you can easily use a 2pdt for that!

Nope - as SeanK pointed out you'll need a 3PDT for the trigger sweep direction. You should be able to find a toggle on ebay - from memory lots of sellers have 4PDT toggles.

well... let me rephrase my previous sentence: I used a 2PDT on my build, and it works...

the wiring is a simple "polarity inverter" thing... no idea what the proper name is... in case you wish to take a look at the wiring, just let me know, I don't have pictures of it at the moment.

MarcoMike - I apologise   - just checked the schematic and noticed that some tags arent used so use of a DPDT is possible.

Did a quick doodle   and came up with this... Assume that the lugs of a DPDT switch are numbered as follows;

1  6
2  5
3  4

+9v connects to lug 3
Ground connects to lug 6
Connection from R10,11,12 connects to lug 2
Connection from the LED 1,2,3 connected to lug 5
Connection from Intes pot connections to lug 1
Jumper from lug 1 to lug 4

Is that what you had?
