I'm selling a lightly used and excellent sounding EMG BTS System onboard preamp, which is solderless. I had it in a bass for just about 3 months. Controls are master volume, pickup blend and separate bass & treble. I left it assembled and it comes with everything pictured. Just attach your pickups and solder to your input jack and you're good to go! These sell new on the EMG site for $129. Asking $79 via PayPal shipped to CONUS. Thanks for looking!
