I felt compelled to update you on my Sinker Redwood/African Blackwood Crescendo (Al Petteway Signature model). I have been playing it exclusively for 3 months now. I started out in DADGAD and then switched to Standard tuning.
At this point I still find myself amazed at this instrument. After a couple weeks in Standard, it really started to open up. At times it sounds like I am playing with amplification–the projection is almost startling. Yet even with that projection, the tonal quality persists–there is absolutely no hint of breaking up–and I can get pretty heavy-fingered at times.
