New PianoDisc iQ Balance Control Boxes. Boxes now have mounting tabs. Boxes have NO wires inside of them. Dual Source and Universal Boxes will ship with one cable. Boxes no longer have a large sticker on the front. The P and A are small vinyl stickers but they actually look like they're painted on the box. All boxes cost $75 even which includes USPS shipping here in the United States. If you want faster shipping, provide me with your FedEx info or simply pay the extra charge for FedEx or UPS.
