Thank you for viewing. I am selling this item to organize my excess equipment. This is an early model of the TECH 21 SANSAMP BASS DRIVER DI, a legendary bass preamp. It's an early model with only the "PHANTOM & GROUND CONNECT" switch on the exterior. Compared to later models, it has fewer switches, making it easier to operate and more simple. Many players still prefer and use the sound of the early models. There may be a difference in sound compared to current models. I'm not using it now, and I might regret selling it, but I haven't used it for a while, so I'm putting it up for sale. - Model Name: SansAmp Bass Driver DI - Brand: Tech 21 - Output Type: XLR output, Parallel output - Controls: Level, Blend, Treble, Bass, Drive, Presence - Country of Manufacture: Made in U.S.A Please understand that this item is sold as-is, with no returns or claims accepted.
