Greetings, tonequester here. I have heard talk on more than one forum about a "passive mid-range booster jack" for Strats, offered by Villex for $112.00. Many people were making and agreeing to the point made about "passive boosting" being like a perpetual motion device.....impossible. I too had the same thought. "It's just a high priced bass and treble cut". However, curiosity cause me to check the website. The only thing I could learn from the website, was that it appeared to have a switch, and that it needed no soldering. Just cut the old jack wires and insert the wires into the "booster", then tighten some screws. I found a phone number, and decided to give them a call.It seems that Villex is pretty much a one man show, and I don't know where he is from, but his accent is heavy. I DID listen to a sound bite of all five Strat positions, with and without the device, and was very impressed. Of course anything can be recorded for playback on a website. I was able to talk to the inventor, and was impressed. It seems that his device takes advantage of the loss of output due to the impedance and loading of the pickups, and is able to redirect that energy into mid range frequencies. he assured me that it was NOT a simple capacitor/inductor combo that simulated mid boost. The bottom line is that after spending a half hour on the phone with him, I have decided to put my money where HIS mouth is, and buy one for my test-bed "Strat". I will report back the results. Either a big rip off, or great tone. tonequester out.:neutral: P.S. Again a loss of paragraph indentation, I'm at a loss, but I apologize.
