Re: Tuner pedals
Most pedals are fine on a dark stage, but a lot of them can't be seen in sunlight. That was my reason for upgrading from a TU-2 to the -3. The -3 is more accurate, and thus can be a little "tinkier" to work with.
The Turbo Tuner has a great rep as an accurate, easy-to-read tuner, as are the Peterson Stomps. I keep my Peterson for my set-ups; my original blue model is a bit fragile for live use, IMHO. I was using a Boss TU-12H, and the accuracy difference is significant. I also have a couple of Korg CA-30s around, an they are very good, but can be hard to read. I keep these in the cases of of acoustics, and used one with a contact mic on my banjo. Having used these little Korgs, I'd have no qualms about using a Pitch Black.
But these days the clip-ons rule. I have some of the Snark Super Tights, and no complaints at all. Not all clip-ons are created equal, so check the specs, and make sure it has an easy-to-read display.
Good luck!
