The best chromatic tuner I've seen.
guys at Guitar Tech have come up with a brilliant chromatic tuner which
could have been designed for hurdy-gurdy. No unnecessary buttons - just
on/off. The display is a big graphic of the note and a useful virtual
needle to show deviation. The whole package is so small that it clips
nicely to the trompette ear so can be left unobtrusively in place. It
seems to sense all strings right down to the low d drone . As well as
using the clip as normal, it's possible to cut off the clip from
the body and then you can use "Blu Tack" to attach it semi -
permanently to the keybox side. The redundant spring clip works great
as a mute for the chanterelles. You
can get one on line for £14.99 + p&p or from me at a bargain £11
inc. uk postage.
