wait a sec.........
you guys tune these things?????
on a more serious note...
I've got a handful of clip ons. The Snark Super Tights are probably the fastest and easiest to read clip on tuners out of the lot I have.
I also have a Peterson V-Strobe 1. The first generation of their V strobes. it's ancient, (I think I bought it 1998) but still works! Deadly accurate, and great for intonation work as long as you set the right tuning mode.
