JackRevive - 1/4" TS/TRS Jack Burnisher

A noisy 1/4" jack is one of the most common problems on any repair bench — but fixing it is not always simple. What starts as a scratchy output jack can quickly turn into a time-consuming disassembly job, especially on hollow-body guitars, amps, pedals, mixers, and other audio gear where the jack is buried behind hardware, panels, or wiring.

The 9Rivers JackRevive is a precision 1/4" TS/TRS jack burnisher designed to restore poor contact inside standard 1/4" / 6.35 mm jacks without unnecessary teardown. Its plug-shaped working end is finished with a fine #1000 diamond coating, allowing it to lightly polish oxidized or contaminated contact surfaces where a normal plug or contact cleaner may not be enough.

As the first tool in the 9Rivers Benchmark Series, JackRevive was developed and bench tested for real repair work — with carefully controlled diameter, coating grit, shaft length, durability, and handle feel. It is built to be a fast, reliable, everyday tool for guitar techs, amp techs, pedal builders, and audio repair benches.

Features

• Fast contact restoration
  Turns many noisy or intermittent 1/4" jack repairs from a 10-minute-to-hours disassembly job into a quick insert-and-rotate operation.

• Designed for standard 1/4" / 6.35 mm TS and TRS jacks
  The working end follows standard plug geometry to reach the actual contact points inside the jack.

• Fine #1000 diamond-coated surface
  Lightly burnishes oxidized or dirty contacts without using an overly aggressive abrasive.

• Useful beyond guitars
  Works with 1/4" jacks on guitars, basses, pedals, amplifiers, mixers, patch bays, audio interfaces, and other gear.

  Provides extra clearance around recessed jacks, control knobs, amp panels, pedal enclosures, and mixer surfaces.

  Tested by 9Rivers through hundreds of uses with minimal visible wear on the diamond-coated working surface.

• Professional repair-bench construction
  Stainless steel body, brass chuck detail, and a comfortable wood handle selected for daily shop use.
