    Great Upgrade For Any Bass
    By Jeremy
    Just picked up an open box 2B-3A version of this preamp (for one-pickup basses) and installed it into a MM SUB bass w/ fretless neck. The tone and presence has now greatly improved, and the "clanky" sound that can come from the stock import preamp of these basses is now at a minimum. The stock pre also has known issues with extremely high (and non-adjustable) output as well as very uneven volume taper along the travel of the volume pot. This Nordstrand preamp fixes these issues and makes the instrument worthy of any live or studio situation. Install is fairly easy as well with included diagram and the components have a solid, well-made feel to them. Highly recommended!
