This is a Warwick MEC BEC-II 2-band onboard bass preamp removed from a 2014 German Custom Shop Warwick Streamer bass. As you can see in the photos, it’s in great condition and everything works excellent > clean and clear with no crackling of pots, etc. It is pre-wired just as it came in the bass for active pickups such as MEC Gold pickups, active EMG pickups or active Seymour Duncan Basslines pickups. The 9v battery clip is also already prewired. You will just need to solder your active pickups to the blend pot and solder the preamp leads to the output jack of your bass. The 4-knob control set up is: 1- Master Volume with push/pull to activate or bypass the preamp 2- Pickup Blend 3- Bass (boost/cut) 4- Treble (boost/cut) Asking $99 + $8 for USPS Priority Mail shipping to the U.S. with payment via PayPal. Please PM me with interest or to ask me any questions you may have. Thanks for looking!
