Here’s my Lark in the Morning Dyer Brothers copy. Lark in the Morning have a bad reputation among harp guitarists and I seem to have been very lucky with this one. I bought it before I heard so many horror stories and before inexpensive alternatives were available. That said this instrument has had several trips to the guitar hospital and all of the tuners have been upgraded.
