Sadowsky Power for Your Favorite Bass For over 30 years, Sadowsky basses from every line have shared one thing in common: a built-in 2-band preamp. The critically acclaimed “Sadowsky sound” is now ready to be added to your rig with the SBP-1 Bass Preamp pedal. Built around Roger Sadowsky’s original FET-designed active preamp, the SBP-1 features the same Bass and Treble controls from his own basses in an easily portable stompbox. A single Volume control easily adapts to your bass, whether you have active or passive pickups. Sweetwater bassists who are fans of Sadowsky’s built-in active preamps are quick to note the authentic character of the boost-only sweep range of the 2-band EQ. Additionally, you get a Tuner out and a Mute footswitch for quick, silent tuning between songs.
