The culmination of over two years work experimenting and prototyping by guitarist Alan Holdsworth and Carvin, the Holdsworth guitar is a no-compromise instrument with a starting price of $719 retail. The chambered semi-hollow body is constructed of alder wood and features a thick set-in alder neck. A premium 1/4 inch alder top finishes the standard body but as an option you can order a flamed or quilted maple top. There are 24 jumbo frets on the 25-inch scale length neck. The ebony fingerboard is flat and there is a teflon-impregnated graphite nut. Locking Sperzel tuners are standard.
