I bought it used 5 years ago and had it revised (regulation and valve replacement) by a repairer.
This chromatic (as the name implies) has a low-C range.
Thus it works better in specific contexts. It is particularly good to play a low or ryhmique accompaniment. Be careful not to play it too loud or the valves might block the reeds. Apart from this, playing is particularly enjoyable thanks to a slide wich is easier to handle than that on Hohners.
