On the subject of electronic tuners.

Thanks to BillD until recently we used korg tuners and tuning clip wires to tune our guitars and autoharps. They just work better than tuners with microphones. I was able to retune my guitar on stage in seconds when the capo or open tunings required it.

But after experiencing the Fishman Matrix acoustic guitar pickup we added pickups (Martin Gold +) to all the guitars and the autoharp. Well, the tuning of the autoharp eased tremendously, since ALL the strings registered, and made it possible to keep the guitars plugged into the tuner in-line with the pickup and sound system.

If purists sniff at pickups, please note that Doc Watson uses a Fishman Matrix and a direct box.
