Re: echoplex- footswitch problem?

Hi dani,
Yes I opened the footswitch box because cable switching didīt help in my case. It is like David said:
>The Echoplex footswitch uses resisters in series with each button to tell
the plex what button was pressed.
This means that every momentary switch  has two states: closed = infinite impedance and open = 0 ohm.
I tell you exactly what I did:
 If you open up the box, you will see, that there is no resister in serie with the record button -> 0 ohm in open state (If you press the button down). 
You can disconnect (you need a soldering iron) one of the resistors that is in serie with the buttons  so you have a second 0 ohm path which gives you a second "record" button.
 If this button now works as a normal "record" button you can be pretty sure that your regular "record" botton is broken.
Since I only have my Echoplex for one month I have no idea how often they have to be replaced. A friend of mine has his EDP for 3 years and no problem.
hope this helps

hi Andre, thanks for response.

you actually opened up the footswitch box?  they had momentary switch with
precisely the right impedance (0 in this case... ok, but what about 681
ohms, etc?)

how often do echoplex users find themselves replacing these buttons?
