​​​​​​PTE PASSIVE TONE ENHANCER

Do you keep your tone control wide open because all other settings are dull and boring?

Want some fresh tones without a lot of soldering or installing a circuit which requires a battery?

The Tone Monster Passive Tone Enhancer (PTE) is our first “no battery required” upgrade for guitar (PTE-G) and bass (PTE-B).  Although often referred to as a varitone, the PTE is actually a capacitor switch that gives you a true bypass position along with 5 filters which removes or reduces (cuts) specific frequencies. Filtering is achieved by sending the signal through different capacitor values. We use polyester film capacitors for a balanced natural sound. The PTE is only 1" X 1 1/8" so it fits easily in most cavities. With simple no solder installation (small screwdriver required), the PTE gives your guitar or bass a new voice in just a few minutes.

If you are looking for some interesting rolled off tones that maintains volume and provides more presence than a traditional tone control, the PTE is worth your consideration!
