For sale a Bartolini HR5.2AP Complete Active/Passive Bass Harness w/ 918 Preamp, 9 volts battery prewired, 5 pots: Volume-Blend-Mid-Treble-Bass. I bought this one brand new less than a month and installed in my bass and it works great but I am more of a passive bass guy so I am selling it. It works perfectly. Just install in your bass and connects your pickups. Price is $125 shipped within the USA. Paypal payment is fine.
