    I have one of these in great condition. It's just not my cup of tea. I have all of the original packaging. The only issue (albeit small) is that the power supply cord has a small nick on the outer jacket that was shaved off. I'm not certain how it happened, though I suspect it came from equipment being drug around a busy stage. The inner conductors were not compromised. I neatly taped it and it's never caused a problem. The features are listed below copied from Gollihur's page.

    I will listen to any trade offers

    • Switchable input buffer (6.8K Ohms/10M Ohms)
    • Low cut filter (multi-setting)
    • Dedicated tuner output (buffered)
    • Three band EQ with semi-parametric Mid control
    • Boost Footswitch with level control (up to 13db)
    • Mute Footswitch cuts output to main outputs (tuner out stays active)
    • ¼" high-impedance output (for amps) with phase reverse
    • XLR low-impedance direct out (DI) with ground lift and phase reverse
    As you've probably guessed, we're primarily offering it as a rock-solid preamp for use with upright bass, but it's equally useful for ALL acoustic instruments, like acoustic guitar, banjo, violin, cello, mandolin, bouzouki or lute (among others). It has lots of flexibility and can be used to enhance the sound of virtually any acoustic or electric instrument.

    So what do all those great features do? The three-band EQ has controls for Bass and Treble, as well as a mid-range control which has an adjustable frequency control (called a "Semi-Parametric Equalizer," it adds a knob to allow you to choose the center frequency affected by the boost/cut, as to better sculpt your tone.) Mids can be particularly useful in helping you to "cut through" the dense mix of a large band, and by adjusting what frequency is affected, you can dial in just the right amount of punch.

    Also tremendously useful: The low cut filter (also known as high pass filter). Piezo pickups have an incredibly wide range of frequencies - including those that are too low to even be heard! By reducing the output of the very lowest, subsonic frequencies, this can reduce the likelihood of certain types of feedbackand can help reduce the workload of your amplifier. Radial actually recommends using the filter in the "bypass" setting, but in testing, we found that using the "low-mid cut" (middle setting) actually improved clarity and total sound. Your mileage may vary, as always - every bass and amp is different - but consider it a good reason to experiment and decide for yourself!

    The amp and DI outputs also have a switch for phase reverse. Why? In some instances, as you move around the stage, you will notice that feedback or resonance seems to increase in certain spots between the wedge monitor and your personal amp. This is caused by nodes either amplifying each other or cancelling each other out at various frequencies. You can reverse the (absolute) phase with the 180° polarity reverse. This can often help minimize this occurrence.

    (Learn more about Semi-Parametric EQ's, Low Cut Filters and phase controls in our "Learn your amp" FAQ!)

    The other features are useful too - the "MUTE" switch is always ready for a quick, silent onstage tune (or just to quiet an instrument not being actively played), and the"BOOST" switch is perfect for when you need to take a solo - or change from pizz to arco (some pickups have very different output volumes depending on whether or not you're bowing). The boost has a variable level setting, so you can set just the right amount of "extra" push, whether you need just a subtle boost or need to go "to 11."

    BTW - never actually used on the floor as a stomp box. It only ever sat on top of my amp, so it's not all beat up.

    Would also be interested in a GK 200MB for a backup head.
