In the last year and a half, i have bought and played:
Hohner piedmont blues (i liked the case, but the harps worked too…all 7 of them.)
2 suzuki folkmasters, both good, but a little quiet for acoustic work with guitar.
5 suzuki harpmasters…all outstanding in every way…if you can use ET tuning…some folks don’t like it.
3 marine bands…one needed a VERY slight tweak on the 3 hole draw reed…it was playable, but not quite right for me…needed too much breath force on that reed only…the other two were and are perfect, and can be overblown on holes 4-6 out of the box. The A is my favorite harp hands down.
1 big river (not very good…until reeds were gapped, now it’s fine.)
6 or so special 20s…all excellent, but an occasional 10 hole blow or draw was leaky…mostly just fine.
2 suzuki promasters…perfect in every way with overblow on hole 6 ootb. Again, ET tuning.
1 hohner bluesharp. I had an older one too…also very nice. I wore the five hole draw reed flat on my c-harp after almost daily playing on it for over a year…my fault…i was bending the 5 hole…yes bending the 5 hole…frequently for a quarter-tone expressive feel. I like the blues harp.
disclaimer, i don’t care if a harp overblows out of the box, but it’s nice if it will. If it won’t, i adjust it
One hohner bluesband…ummm…playable, but pretty leaky. I like to use as little air as possible and this one didn’t cut it for me…didn’t try to tweak it though. The piedmonts were all better in my experience.
Favorite? I like them all…i will buy based on the requirements for the music i will use it for, knowing what i know of them.
