Washburn acoustic guitars / big oval soundholes: M1/M80 Answer with pictures.
The final proof! Sorry about the delay since last post, but I eventually decided for the M80. I had it fitted & it sounds great.
[I think it sounds better with the B pole-pice back in, but will start a separate thread about that.]
You can see how it fits in the pictures better than I can explain it, but there is
a) ~1/8 inch clearance between pick-up & end-of-fretboard
b) sufficient contact area for robust grip (not moved yet) & sound transmission - I can't compare to how it would sound to a simliar guitar with a round sound hole as I don't have one!
Attached are 2 pictures with pickup fitted
1. showing whole body
2. showing close up
I hope that helps!
