Tuners.

Another +1 for the Korg Pitch Black tuner. Fast, reliable, accurate. Sold the first one I had, missed it so much I bought a new one.

Korg pitchblack
If youre willing to spend a little more, then get the ST-200

GFS GFT-90 Tuner. Big, bold display like the Pitchblack. Has an out and bypass-out connection. On the normal out, it mutes the signal, on the bypass-out, it doesn't mute. True bypass. Not expensive.

+1

I like the Korg Pitchblack, and the Digitech Hardwire tuner.

I use the Korg Pitchblack+ Great tuner

Pitchblack.

Great for your pedal board as it is nice a slim and can fit in those little gaps.
Super clear read out and fast to find the note.
