I've just been through an enormous hassle on this topic. It started
when an Eventide DSP4000 owner I know bought a volume pedal and a
Digitech FS300 in order to control her Harmonizer. She bought them
mail order after consulting with that vendors "sales tech." Neither
controller worked. Since I'm an Eventide user I loaned her a couple
of my controllers (an Ensoniq CV pedal and a Lexicon dual foot
switch) and I started researching what was available.
I found that there is almost no product information that specifies
whether a pedal or a device to be controlled uses a TRS or a TS
connection. What I ended up doing, at least for on-line research) was
to find hi-rez pictures of the pedals in order to look at the 1/4"
plug. In many cases I could then determine whether the pedal was
wired with two or three conductors.
I've now learned that it's always wrong to assume anything. I don't
have an EDP so I couldn't check it out directly. I assumed it was
designed similarly to the equipment I do have. Wrong!
I think it would be generally useful to compile a list of which
common pedals and which common devices are TS and which are TRS.
Here's my (hastily compiled) list. For those pieces of gear I have on
hand I checked the voltage between ring and sleeve by plugging a TRS
cable into the pedal jack on a number of devices. Otherwise I went by
(minimally available) company-provided specs, hearsay, and pictures
of the 1/4" jacks.
