The Gronitz PF125 is a large piston F tuba made by Andreas Klingspor in Bavaria, Germany. This in-stock model is polished brass, without lacquer. Unlacquered finish feels more resonant than lacquer, and is less expensive than silver plate. Several years ago I had an unlaquered model here that had been repaired, and it was outstanding. This was built to replicate that, and it satisfies. Equipped with Martin Wilk MAW pistons, the ease of playing this new Gronitz is captivating.
The PF125 large 4 piston, 1 rotary valve F tuba is designed in the modern style of the newer piston instruments. With a broad, velvety smooth tone and an even response throughout its range, this tuba is a useful horn for nearly anything. The low range rivals that of much larger instruments, and the low C is perfect with a full tone. With its even response between open and heavily valved notes, you will be free of the sort of quirks that can plague most rotary F tubas. There are no notes that fail to resonate, and the slurring is effortless. While being similar in size to the Yamaha 822 model, this Gronitz has a liveliness and character of sound that puts it ahead of the Yamaha for many players. The fifth rotor is standard tuned to flat whole step. In raw brass, lacquer or silver plate. 19-20-21mm conical bore, 16.5" bell.For 2018 all Gronitz piston tubas will feature MAW pistons by Martin Wilk, made by Meinlschmidt.
What's captivating about the Gronitz is how light they are. Made mostly from lighter gauge sheet brass, these have a liveliness of response and a velvety tone that reminds us of the other lightweight tubas out there like Rudolph Meinl, Alexander, and Adams.
This tuba can feature a small second valve slide pull stop, so you can adjust the 2+3 Ab a bit lower if necessary. This model of tuba plays well in tune throughout its range. All F tubas have pitch quirks, and this is no exception, but they are very minor. You may want to pull the first slide a bit for Bb and A in the staff, and many F tuba players on other instruments finger the A with the third valve to keep the pitch low enough. You may need to lower the Ab a bit, easily done with the second or third slide. Some players might average the third slide pull between Ab and Db.
