MOTM

Hello List,

I have an old Volume/Modulation pedal that I got with my original DX7 
back in 1985. I'm trying to measure the resistance to see how to use 
it with the pedal interface but I'm not getting very clear numbers.

I get readings between 25 and 40 most of the time with the pedal up 
or down. It does go up to as high as 150 sometimes but very briefly 
(could this be my DVM? It's quite cheap). 

Also, I only get readings with leads on the very tip and behind the 
first ring on the plug. I get nothing with one of the leads between 
the two rings (and the other on either side of either ring). Is this 
the way the newer Yamaha pedals are wired?

I'm just wondering if older pedals might have been made a bit 
differently than the newer Yamaha pedals or if they should be 
somewhat similar (if anyone has any experience with older pedals). 

I appreciate any suggestions or insight anyone might have!

Thanks,

John Broaddus
