Today, we’re going to talk about the bass rolloff modification, which changes the way a standard tone control operates. Ordinarily, when you turn the tone control, you roll off the high-end frequencies, and the tone becomes warmer. With this modification, we are going to reverse that, so when you turn the tone control, you roll off the low frequencies, and the tone will become brighter.
Does your tone get muddy when you turn your volume down? Learn how a treble bleed circuit fixes this problem.
The treble bleed circuit is one of the easiest mods that you can perform on your guitar. It’s one that might require extensive experimenting, however, before you’re able to get it perfect. The treble bleed is meant to preserve treble loss as you turn down the volume control on your guitar. It does this by creating a very simple high pass filter to counteract the high-frequency loss inherent in the volume control. You will want to add this mod to your guitar if you feel that rolling off the volume causes your tone to change too dramatically, thus becoming muddy or dull.
