Upgrade the sub-par machine heads on your electric guitar with a set of high-quality Sperzel Trim-Lok tuners. Thanks to their ingenious locking design, these machine heads eliminate the need for multiple wraps around their string posts. Simply insert the string into the tuner hole, tighten the clamping wheel and the string will be fixed firmly in place!
Apart from making string changes incredibly easy and fast, this locking design ensures better tuning stability as no string slippage can occur. This is particularly important with tremolo-equipped guitars.
