TUNE-IT – Redutor de atrito de cordas com instrumento

Sou o único que não conhecia este tipo de produto que promete reduzir o atrito de cordas com o braço e com o corpo de um instrumento, prolongando, assim, a afinação deste e reduzindo os eventuais ruídos indesejados delas, quando tocadas?

"TUNE-IT – Your Personal Guitar Tech in a Tube

PR – MusicNomad Equipment Care (www.MusicNomadCare.com) - Stop tuning between every song!  Music Nomad’s TUNE-IT is your personal guitar tech to keep you in tune longer and reduce string breakage.  Our pro strength formulation is like no other because it contains anti-wear, anti-oxidants and anti-corrosion additives fortified with PTFE (Teflon).  The precision, pin point applicator tip makes use easy with just a squeeze of the tube.  TUNE-IT’s clear and non-staining gel should be applied every string change on all the string touch points such as nut slots, bridge, saddle and string guides to reduce friction, the culprit of off tone strings.  In addition, it reduces wear and tear to moving parts such as open turns, tremolo bars and more.   It’s non-melting and water resistant properties mean it does the job longer, allowing you to sound the best.  Like many of the other products in the Music Nomad family, it’s environmentally friendly since it’s biodegradable and free of petroleum and silicone.

Rand Rognlien, owner and product developer of Music Nomad Equipment Care, says, 'We field tested TUNE-IT for a year with top repair shops and techs.  They love what it does for the guitars they service.'  Joe Glaser of Glaser Instruments in Nashville, Tennessee says, 'TUNE-IT is our preferred nut and saddle lube after trying all the usual suspects.  It minimizes friction nicely, doesn’t build up and, most importantly, does not affect the sound or sustain of the strings.'  Rognlien’s 15 years of experience making high end car care products contributed to the success of this high performance lubricant.
