Are instruments, in general, built to work at a certain frequency?
That would be ideal but difficult to implement in reality; therefore they _happen_ to sound better at certain frequenc(ies), not obligatory those intended ...
Recently I started to tune my five course guitar in 415, but I think the sound is a bit muffled...
It may simply be because you are used to it being tuned higher up. A lot depends on your actual guitar model and string length of course. Say, for a 'typical' 17th century guitar, with 68 - 69 cm SL, tuning it in E (a' 440) would certainly be too high sound-wise (well, at least in my experience), a' 415 is better, a' 392 is even better still.
Should I use thicker gauges?
Yes. AB To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
