What’s so special about this ’50s wiring? It affects your tone in three major ways:

1. The overall tone gets stronger, tighter, and more transparent. It’s difficult to describe, but you might say it’s more “in your face.”
2. The typical treble loss that occurs when rolling back the volume is much less than with standard wiring. Both the volume and tone controls become more responsive, and they react more smoothly without the usual hot spots. Another bonus: By simply rolling back your guitar volume a bit, you can clean up an overdriven amp without getting lost in the mix.
3. The tone and the volume controls interact with each other—something you might be familiar with from certain tweed-era Fender tube amps. When you change the volume, the tone changes a little bit as well, and vice-versa. This may be strange at first, but you only need a few minutes to get used to it.

The ’50s wiring exhibits much less treble loss that standard wiring because it follows a completely different curve, depending on the ratio of your pot. It works best with audio taper pots, preferably those with a 60:40 or 70:30 ratio. Smaller ratios like 80:20 or 90:10 limit this benefit and result in the typical “on/off” or “bright/dull” problem when using the controls.
