Just wanted to touch bases with you and let you know about a product I have found to be very useful indeed. It is for those of you who use a smartphone or tablet and is called "Guitar Toolkit" made by Agile partners.
It cost me £5, don't know how that translates to $, either way its a steal. It has a tuner, which covers most instruments, different tunings, chords, scales, arpeggios etc etc. So you might like to check it out.
Also D'addario have released a nice little tuner if you prefer a hardware unit. It is called the "Eclipse Tuner" link here :
