The Schaller GrandTune 3+3 machine heads combine traditional open-gear styling with precise, consistent tuning performance. Designed as a classic tuning machine, the GrandTune focuses on mechanical accuracy, smooth operation, and long-term reliability.

A 1:18 gear ratio provides fine tuning control with a stable, fluid feel. The mechanism is manufactured without synthetic coatings, allowing direct metal contact at critical interfaces. This construction supports resonance transfer while avoiding wear associated with ageing polymer layers. Precision-machined contact surfaces ensure smooth operation and consistent performance over extended use.

The tuning mechanism uses permanently secured, sealed screw connections to maintain alignment and minimise maintenance requirements. Dimensions are based on common production guitar specifications, allowing straightforward installation or replacement on most series instruments.

Special features

Precision-machined contact surfaces without polymer coatings provide consistent lubricity without wear or degradation over time.
Sealed and permanently secured screw connections ensure stable, maintenance-free operation.
Standardised dimensions support compatibility with common production headstocks.

Measurements just didn't add up.
Size: X-Large, Color: Sky Blue
Quality of the shirt was nice but the measurements did not add up. I wear a 17 1/2 neck and 36/37 or 37/38 sleeve. I ordered an XL and the sleeves were a little to short and the neck was way to big. Could never wear a tie with this shirt. So going up in size wasn't an option because of the neck. The next size up that had longer sleeves was a 3X, not happening. So if I went down in size the sleeves still would have been to short and the shirt would have been to tight. If the shirt fits you then you have a good shirt at a great price with lots of colors.

Great purchase
Size: Large, Color: Blue Shark-white
Shirt was the perfect gift for my 21 year old son. The small pattern was perfect and he said that made the shirt cool. The material is comfortable and light enough for warm weather without feeling cheap. Shirt is versatile with the ability to dress up or down.
