    Yes, it would appear the switch you bought is incompatible with the RBI unit. When all else fails, read the manual.

    To the OP:

    You bought a marshall footswitch? The RBI is not build by marshall...

    You need to use a latched footswitch with the RBI. The footswitch should have a solid "click" like a true bypass pedal when you use it.

    I'm very aware that it's not a Marshall product. The footswitch does click. Their website mentions no tech21 switch that I can buy online. Great
     
  6. IIRC, Fuzzbass says his SWR-IOD switch does not work with RBI either.
    I own the IOD footswitch, and will try it out this weekend with my (new to me) RPM.

    Marshall P801 is a latching switch. You did plug it into the footswitch jack and not the "footswitch out" jack, correct?
     
  8. Many Marshalls use logic state switching (don't use a shorted connection to ground). You could modify the one you have or there are footswitches out there that do truly latch and have a battery supply for the LED inside the footswitch.

  10. The 801 latches through a 1K resistor in series with the LED, not directly tip to sleeve.

    I forgot to mention, you can test the RBI. Plug an instrument cable into the footswitch jack and touch the tip to the chassis of the RBI. The unit should switch each time you touch it to the chassis. As the previous poster suggested, make sure you are plugged into the footswitch "jack" and not the footswitch "out."

    I got the same problem with my RPM.

    Thank you for the idea to test it by touching the chassis with an instrument cable .

    I tried two footswitches so far. One is an Ampeg AFP-3 which IS a latching one with one stereo and one mono 1/4 jack and LEDs.
    The other one is a Behringer which connects only connects tip and ground as long as you press it.
    The result is that the RPM is active until ich stop pressing the switch
     
  13. Just a word to anyone, just because a footswitch is "latching" does NOT mean the way it is wired electronically is compatible. A latching switch can be "hard" switching or "soft" switching.
