This is an early model SansAmp. I purchased it used and used it for live performances and recording for about a year. I am selling it now to raise funds. I do not have any pets, and I used it in a smoke-free environment. There are no operational issues, and I don't see any crackling. This is a sale of the unit only. I plan to ship via Kuroneko Yamato. *Please note that I may suddenly cancel the listing, so I recommend purchasing early if you are interested. ----- A bass effects pedal that allows for a wide variety of sound creation. - Model Name: SansAmp BASS DRIVER DI - Output Terminals: XLR Output, Parallel Output - Controls: OUTPUT, TRIP, BASS, DRIVE, PRESENCE - Country of Manufacture: USA - Active Indicator: ACTIVE LED Thank you for looking.
