The Bluesbox Collection The neck attachment is a wonder! This curved bushing allows the neck angle to be adjusted, by loosening a giant wingnut accessable through the sound hole. The peg head is faced with simulated mother of pearl (sometimes referred to as "mother of toilet seat" by collectors) and trimmed with gold stencil, which has faded away to some extent. One of the interesting things about this guitar is that it is the only arch top I own that has a twelve-fret neck. This gives it a "Maccafferri-like" tone - very brassy with a lot of punch.
