The RawSound Varitone is becoming rarer by the month because the maker is now residing in heaven. With a degree in electrical engineering, Andy Padilla entered the electronics biz in 2008 with his solder-less Varitone units. But he passed in February of 2012 barely 4 years into this endeavor. We discovered Andy's work and actually installed these harnesses in several of our passive Buscanti Newport Basses. We had established a great rapport with Andy and were so saddened to learn of his sudden passing. At 37, he was much too young to leave this world. Since we're getting out of building basses for an indeterminate period, I have decided to sell off a couple of our prewired harnesses and hang onto a couple in case a current customer needs one. These are really nice well made units. Easy to install. Just screw down the lead wires into the harness and you're ready to roll. The config is Volume, Volume, Varitone, on/on toggle switch , Standard Passive tone. So with the toggle being switched, the options are as follows: Position 1. standard Jazz bass config turned on, or Position 2. six stage varitone turned on. Here's a YouTube video that Andy created that gives you a tour of this device. You'll see that he has his bass wired up with Di'Marzio Ultra Jazz DP 149. We've incorporated Basslines STK's and a Tesla pickup called VR B1 pickups as well with great results. My price includes insured shipping anywhere in the continental US and 3 screws for the plate. Photos are pasted below and here's that 2008 video made by Andy: Thanks!
