The TOWNER V.BLOCK, by itself, is designed to accommodate Les Paul Jr type guitar bodies with wraparound stop tailpiece bridge.
TOWNER V.BLOCK, is designed for the BIGSBY® B3 and BIGSBY® B7 vibrato tailpieces ONLY.
The TOWNER V.BLOCK is designed set the BIGSBY® spring cup back 1/2? inch from butting up against the bridge post or stop tailpiece stud.
