This is a "Musician's Gear" PT-10C pedal tuner with Maxon power supply. It also will operate on a 9V battery of course, but I always used the wall wart. I've had it for close to 2 years, but upgraded to a Korg rack tuner. It always worked for me. $20 shipped to USA.
Here it is tuning an A note.
Four new CTS 250K pots, split shaft. I got them from another TB'er a while back but haven't used them. These have the somewhat open back (a friend of mine has an older G&L guitar that has pots just like this, stock from the factory). $15 shipped to USA for all four.
