Or buy a tuner that produces reference tones.
Any chance you could enlarge on this? I haven't heard of such animals before.

Yep. I recently mentioned mine for instance on another thread. It's one of these:
Intelli IMT-301 (bought 'cos I was impressed by the one my oboe teacher has).

For details see
http://www.staffordguitar.com/reviewsmetronomes.aspIt's a chromatic tuner over 8 octaves and will also play reference tones over that range. It has a volume control (some don't) and a good metronome too along with a big easily readable display. It's not small but in the context of carrying an instrument plus accessories plus music, it's OK (any smaller and I'd mislay it anyway). Oh and it's cheaper than the Korg or Seiko competition.
