K&K Golden Trinity Mic Upgrade Kit for Double Bass. Includes lightweight condenser mic, preamp/blender and cabling necessary to add to any piezo transducer. Sounds very warm and natural, allows you to blend mic and pickup signal to get the true tone of your bass. Everything included, but you'll need a strip of the dual-lock (super Velcro) to attach the mic to the bridge, or some adhesive to reattach what I'll include. In otherwise mint condition and is only 3 months old and has seen little use. I really like this setup a lot, but I'm playing with guys who are addicted to LOUD monitors.
