Hi Bernier,

I love the Boss TU-3 Chromatic Tuner pedal. Easy to use, well-built, and can handle instrument or line-level signals. I've never had great luck with software tuners.

I have mine hooked up to a pre-fader send on my mixer, so I can use it to tune synths, guitars, bass drum on my drum machine, etc, by just turning the send knob on that instrument's channel. Can also just plug a guitar into it normally, I suppose. wink
