Re: EFC-7 issues

Excellent idea. Somehow my multi-tester went MIA - have sent out a search party - my brother loves to borrow tools without asking... Meantime, I tried this test. I plugged in a standard keyboard sustain pedal (yup, into the footpedal jack!), and tried both long and short presses... the Echoplex acknowledged that something was wanting to happen, but it sure didn't perform a record function... 

sound like brain damage? And if so, is there a schematic available anywhere?

OK, if we rule out the switch.

You can look at this:-


but there are other things you could check first.

If you have a meter for resistance..
plug lead into EFC-7
hold down Rec
Check resistance across jack terminals, should be 0 ohms.


Plug lead into EDP Footswitch jack.
Then see if you can trigger Rec by shorting the jack terminals.

Having done that we can tell if the EDP is faulty.

If it is, then probably you'll need the assistance of a technician.

Right - I only wish it was that simple...

the problem with the switches is really common.

It's still possible this is a switch issue from what you have said.
