These single bridges are perfect for extended range and multi scale headless guitars. Unlike other custom brands out there, these are easy to install with two screws and eliminate the need for base plates or routing. These are hard to buy elsewhere, especially in the U.K., without ordering from ABM directly. Anyone looking to build their first headless electric I would suggest these over any other. If you have experience with headless guitars and use other hardware, I would suggest trying these purely for the ease only install and use. Many custom handmade guitar businesses use them in their builds for their clients so they are rugged and not a worthless purchase. I love these and will continue to buy more through thomanne due to the price and the fast shipping that took less than a week to delivery. Please Thomann keep stocking these!
