The ModTone Signal Booster is exactly that, a clean way to boost your volume. Designed along side a US effects modification company, the ModTone Signal Booster offers up to 25 db of volume boost without adding any distortion to your signal. The Signal Booster also features an added Tone knob allowing you to also use it as a Bass or Treble boost. It also works great for your acoustic/electric guitar if your guitar does not have onboard volume and tone controls. The ModTone Signal Booster will run great in front of your amp, but throw it in the effects loop to maximize its potential and boost your rig to new heights.
