Schaller Lyra Acrylic NI

The old machine heads of my guitar weren't usable anymore and bought this set after some research.

I can honestly say these are more stable, except the D string needs to be turned more before it starts reacting. This could be due to the new strings, only time will tell, but its still usable.

I don't know if I am imagining it but I get the feeling that these also make my guitar sound a bit better than the cheap stock machine heads that it had. maybe its because they are heavier and have more mass.

Schaller's tuning set solved a problem with a middle priced classic guitar. The worn out machinery was easy to change thou it needed some small adjustment.

Tuning is absolutely easy with an accurate fine mechanical machinery. The difference to the original tuners is huge. That's why I can recommend this product to all who have the same problem with cheap or middle-priced acoustic guitar. - Maybe there are even better Schaller tuners for very valuable instruments...

Bought to replace manufacturer tuners which had started slipping after 7 years. These seem to hold the tension well and were easy to fit.
