Hi most luthiers will build a requinto if you ask Ive got one by dave Gregory
its on loan from a friend who only plays 8-10 string now
its a bit different so have included a photo
cut away 24 fret extended finger board with a sound post inside
The Granados /esteve range are V good off the shelf
Ive got an Octave and contra bass so the requintos should be too.
Also Burgette do a range that are also good I have the Baritone and terz so again the requintos should be ok
try an ensemble using 3,4,5 different instrunents it if a different world.
