You know what this classic is. Mint condition. Used a few times, like new in box. Everything works perfectly. These sell for $169 new. I have been using this primarily with the U-Bass. 10meg-Ohm input, appropriate for any instrument. The sound is very true to the tone of the instrument. Among comparable preamps, this one is very strong yet tight in the low end and very upfront sounding. Tons of headroom. The set 35 Hz High Pass filter really makes the low end tight. Can't say it enough. This box is tough as nails. Asking $125 shipped lower 48.
