I've been using this tuner for about 1,5 years now.
Mainly with 6-string NT F#BEADG HB6000 bass, early 90's Gibson Firebird and SN Japanese Tokai LP's.
Works very well and fast for 6 string e-standard guitar.
Works adequately with 4 string e-standard bass.
Struggles a bit with bass B-string.
Tracks very randomly bass F#-string, almost useless.
The tuner has a lot of different features, but I feel that those are pretty hard to use and therefore I've only used it as astandard tuner.
The swiveling joint enables lots of different angles the tuner can be used at, which is very user frendly, but might also diminsh the sensitivity a bit.
Great tuner to have in recording sessions, where one has to keep an close eye at the tuning between the takes.
