    I play mostly blues and enjoy the sweet overdrive of the RBI. Very SVTish. However, when I engage the sansamp blend, some of the mids are cut out and the presence gets kinda harsh sounding.

    Anyone tell me if the SWR Interstellar OD preamp has a mild overdrive or is it in your face distortion?

    hmmm i guess i missed this the first time around.

    the SWR IOD can be dialed in from anything between a warm tubey sound, to a gentle overdrive tahts touch sensitive to a buzzsaw-like hard overdrive, and even be blended back for a smooth fuzz with everything inbetween. definitely not a harsh sound, i would describe it as being warm with a soft attack.

    What tubes does the IOD use?

    Does it scoop the mids like the RBI when the drive is turned up?

    it uses a 12ax7 and a pair of el84 power tubes into a 8 ohm resistor.

    I've owned the IOD and played around with the RBI and I definitely prefer the IOD. I couldn't get it to sound harsh no matter what I tried.

    to me it doesnt scoop the mids....when you crack the drive thats all it does....i cant notice any scoop to my ears.

    boost the OD to its max and you will lose lows, not mids.

    I have owned both the RBI and an IOD. I sold the RBI--I couldn't get a good sound out of it. The IOD does that sound much better, to my ears....but you have to learn how to work with it (i.e. combine gain, blend, phase and EQ properly)

    I've ended up spending most of my time with Bassman-inspired units like the TE V-type.

    Having never heard a Trace V-Type, how does it compare to the IOD? Does it have a simliar purpose in life?

    No. I have both.

    The V-Type preamp doesn't really distort, per se. I actually use the IOD clean most of the time, and the V-Type when I want its particular sound. It's a bit cozier than the 'Stella.
