Great energy and resonant from low C all the way up!
Geert has recently been making a great name for himself with his flutes. This is the second one I've played (we also have an Eb in stock!) and both are stellar instruments. Very responsive "alive" instruments. From what we've heard, his current wait time on keyed instruments is from 1-2 years.
With lower flutes, makers often have to make more of a compromise in tuning on the 7 / b7 note of the scale (would be C#/C notes on a D flute - on this C flute, we're talking about the B/Bb). This flute is tuned so that you have to "lip up" to bring the B into perfect tuning, whereas the b7 note / Bb is spot-on with the standard 0xx 000 fingering. This is very common with low C and low Bb flutes. It's true of my personal Wilkes Bb. - Blayne
"My C-flute design is not just an extended D-flute. It has a different bore and the finger holes are rather large. The sound is dark and powerful, and already surprisingly different from a D flute. The C flute is an attractive option if you are going to play together with instruments in C of in F. This flute sounds great when playing music in C or F and it allows you to avoid the struggle with keys on your D flute. The flute can be provided with up to 6 keys."
