M9 / M13 expression switch? Looking for diy info

[Faraldi]

I did a search but I'm not sure exactly what they're called. I'm looking to build a switch that allows me to change expression settings for a preset on my M13. Basically a switch to use in place of an expression pedal. Any help is appreciated.

Get a boss latching footswitch and plug that sucker in.

A cool effect I have found is to hook up a momentary footswitch (like a keyboard sustain pedal) and set it to control the volume perimeter for a kill-switchy sound.

Sorry, didn't see that you wanted to diy... Oops!

Buy a stomp box footswitch from

And an enclosure + jacks + wire from

http://radioshack.com


And hook it up so that the switch connects/deconnects the two pins coming off the jack. Maybe even hook up a battery/resistor/LED setup so you can see if it's on or not...

Thanks man. So is it really just as simple as a break in a circuit? Is there a need for a small value resistor? ( I know enough to get myself in trouble) :)

Not entirely sure... It should work. Try by plugging in a cable and connecting the two parts with something conductive, then unconnect them. See if it works!

Yep, I'm going to give that a try. Thx man,

I'd like to build a expression control for my M9 that is a just a big ol' knob I could rotate with the side of my foot.

I use an ernie ball 6181 volume pedal as an expression pedal for the m9, which works great. It has a 25k pot. If I just wired up a 25k pot (linear taper?), would that work just as well? Thanks gents!

Not entirely sure why you would want this, but I guess it should...

Faraldi,

It's not a simple circuit breaking switch, but all you need to do is put a 10k resistor between the lugs of the switch.

I took an old orphaned peavey three button footswitch, got rid of the middle switch, wired in a couple of 10k resistors, cut the lead to about 2' long and added two 1/4" plugs to the end so I have both expression switches in one housing with built in cable.

I haven't used it yet other than to make sure it works.

Thanks very much. Dumb question... is the connection of the two wires connecting the tip and the sleeve?

[Teleworshipkid]

Yes. There is no where else to put them!

Told ya! I'm dangerous with a little info.

So when the circuit is off, there's still a connection but it's got that resistor in the way, thus giving the M13 what it needs to function?

Please don't hate me. :)

[Teleworshipkid]

Yeah. It has to have a detectable amount of resistance to acknowledge the presence of a pedal.

Holy cow!!! I think I actually may understand this now!

gatimberframer and Teleworshipkid and all, THANK YOU!!!

Now to build.
