The Dynaguide is a new concept in string tree/guides that helps solve detuning problems and features a self-aligning string angle. Instead of fighting friction between the string and guide, it relies on that friction to swivel a square ring in the base near to the headstock. Its inventor says the design eliminates tuning problems, particularly on guitars with flat headstocks and Strat-type vibratos because it keeps the strings from binding. The Dynaguide is available in black and off white for matching your pickups and/or knobs. It is designed and manufactured in the Netherlands.
