    Is anybody using the Raven Labs PMB II to blend a Realist and an Underwood?

    If so, which input are you using for which pickup, as the input impedence and frequency response is different for each of the inputs.

    I'm useing a Ravens lab blender
    with my underwood and my realist.
    Underwood in the top channel, which
    has a 10 mg ohm input for peizo pickups.
    I put the reaist in the bottom channel,
    which is set up for mic's and regular
    pickups. IMPORTANT!! The phase switch
    can have a big effect on the sound!
    The underwood gives me the note center
    and captures the sustain. The realist
    gives me that old-school thumpy bass.
    I mix the two sounds depending on my
    musical needs. Hope I could help.

    I never really got into the whole mega-ohm business, but I wondered if it mattered that the bottom input of the PMB II was designed for mics or magnetic pickups. Have you tried switching the Realist and Underwood around, since they both are piezo type pickups?

    Also, is the PMB II better for acoustic bass than the MDB 1 (the latter is about $100 cheaper). I have a Realist on my main bass, and an Underwood on my second bass, and have always been wondering what the two would sound like if mixed together.

    The MDB-1 handles three inputs but it does not have EQ for each channel.

    FYI, I can and have special-ordered PMB-II units with 10 megohm impedances for both channels.
    Same price.

    Sorry. I've been away for a few moments.
    Yes, the bottom channel is good for mic's
    and regular pickups. Sometimes if I have
    to double, I'll put my Tyler 5 string in
    the bottom and my underwood in the top.
    Works really well. I,ve tried the underwood
    in the lower channel. It lacks some tone.
    Anton. I realize you are not into the whole
    "mega-ohm business", but it matters!
    For many of us, our sound, be it amplified
    or acoustic, is our signature. I'll get
    educated or spend a few extra bucks because
    I think it matters.... anyway....
    The realist has much low end thump. It works
    better in the lower channel. I'm going to put
    on a Wilson pickup with the realist, but the
    underwood works very well. Enjoy experimenting.

    Would it make sense to send the Realist through a Sadowsky outboard, just for impedance matching purpases, and then into the mic input of the PMB II?

    The sadowsky is not a 10 megohm preamp.
    It just happens to work well on some basses.
    You could use it instead of the raven labs
    THE BETTER!! No one I know seems to need a
    special preamp for the realist, unless its to
    take lows away. I use the underwood in the top
    channel. It gives me the articulation and more
    focused sound. The realist in the bottom channel
    gives me more old school thump and boom. Mixing
    the two has been very nice. Again, the phase
    button has a big effect on the sound.(in or out
    of phase) The sadowsky works well for backline
    amps or home studios, with my electric bass.
    I can bypass the preamp on rental amps, or use the direct out for home studios. Sadowsky is a
    great company to deal with. Hope this is of some
