    Hi,
    Not sure if this belongs in the pedal section so I put it in both.

    I am ruuning a 2 amp set up here. A caa-od 50 el34's into 60's 4x12
    a bogner shiva into orange 4x12

    using the drive channels on both amps

    I am putting my EH DMM into the effects loop of a CAA od50 el34's only


    so when the DMM is bypassed and the 2 amps are set to have a nice blend the sound is full and rich.

    When I engage the DMM with the blend set to no effect and the input level set to unity gain the signal becomes out of phase.

    bypass the DMM and the signal is back in phase.

    Of coarse if I put a Barber launch pad which reverses phase in line with the DMM the problem reverses itself, out of phase when the DMM is bypassed.

    This problem creates the effect needing to be on at all times scenario.

    any thoughts?

    thanks
