TECH21 SansAmp Bass Driver DI preamp. Selling due to equipment reorganization. Overall in good condition, and has been tested and confirmed to be working. No crackling or noise, and is in perfect working order. This is a discontinued model, and although the details are unknown, the jack section is the same specification as the V2, making it a rare model. Please refrain from purchasing if you are concerned about minor details, as this is a used item. No pets. I smoke. I do not smoke in the storage area, but please be aware if you are sensitive to the smell of tobacco.
