Let me assess this carefully and share my learned findings with you:
1. I'm very firm about the master volume control being positioned too high on this particular specimen. Having rammed that point home, pinky reach might have been an issue for swelling effects.
2. Some of the other arrangements are a bit muddled too: garter belts worn over panties tend to get in the way at the most inconvenient times - form should always follow function.
3. But - all in all - a commendable improvement over that hapless furry guitar that started this luthier's wet dream of a thread.
4. Finally, the first 13-string bass I have laid eyes upon, such ingenuity: an ultra-low G tuned to A.
