Most style IIIs have no more than four. This is the other hot selling high tech bridge. Imported wood, rounded top edges to reduce overtones. For moderate intonation problems. Only bridge available here in which slight arch offsets head sag.
Unique design compensates all strings.
Recommended if extremely bad intonation problems exist. Popular among old time players for brighter tone. Light' produces brighter tone, 'heavy' produces bassier tone. For straight bridges only, won't work on Moon or Enterprise brands. T-wrench for adjusting bracket nuts.
