Like all of AboveGround’s pedals, the Tone Control/Booster is a unique design that performs its tone mutation duties in a novel and very effective way. Tone Control/Booster modifies the signal content just outside the fundamental frequencies of the guitar in a soft response curve. This manipulation of adjacent corner frequencies makes it super easy to dial in the amount of harmonics and sub harmonics, greatly expanding the tonal possibilities of any guitar. Tone Control/Booster’s discrete, two-transistor circuit is incredibly amp-like in its tonal quality and feel because it’s of the Shelving Control Filter variety instead of the usual parametric. This incredible flexibility means it can be used anywhere in the signal chain for different purposes. You can use it to define your foundation tone, or as a clean tone change for different parts of a song or different songs in a set. With 15dB-18dB of boost within the audio spectrum Tone Control/Booster can alter the tone and boost output when paired with another pedal or pedal chain, or boost the bejeezus out of your amp’s input. And if that’s not enough to get you interested, it’s also great for recording direct to the mixing board. Tone Control/Booster’s wicked flexibility makes it one of our all-time favorite pedals.
