If you experience tonal change when turning down the volume control on your guitar, the Fender Tone Saver 250K is a great solution. Unlike traditional treble bleed circuits that involve connecting tiny parts together with delicate soldering, the Tone Saver contains a special R/C network inside one convenient enclosure that will keep your guitar's tone remarkably consistent at any setting. Just solder the leads to the center and outside lugs of your guitar's volume control and you're done. The Tone Saver 250K fits most vintage and modern guitars with 250K control pots.
