This is a non-destructive way to add a B bender to your guitar Tele, Esquire or any guitar that uses the same bridge. This bender mounts to any vintage 3 saddle Telecaster bridge without modification. The bender replaces your B and high E string saddle and gives you a half or full step bender. Most people run them as a full-step to do pedal steel imitation country licks. It's machined in America out of solid brass and it's in great shape with all hardware, original adjustment tools, and the instructions. I really enjoyed using it and have since upgraded over to an Allparts/Certano B and G palm bender bridge.
