A work mate of mine has an M. Suzuki W450 - very ornate MOP and solid Indian RW B&S. Top is, of course, solid...maybe spruce.
Ruben, the GuitarRepairMan in Melbourne brought it back to life for him and is it very good. So good that I wonder if Sada Yairi, who learnt his initial chops at the Suzuki Violin Co. may have had some influence. I did read recently (the unsubstantiated web stuff) that Sad continued so sort of association with the SVC over the years. Probably just hearsay.
But my main point is that there is stuff all out there in the WWW on M.Suzuki steel strings.
Can you shed some light on these guitars?
