Guitarists need to seamlessly cut through and fall back into the mix. As the name suggests, the Qboost is a semi-parametric booster that allows the player to choose the precise frequency to boost in order to get out front, or to push the preamp with certain frequencies. The range of the Qboost’s unique tone filter is much akin to that of a wah-wah. Boost middle frequencies for a cutting tone, push a preamp with precise frequencies, or to keep the unit switched on for a personalized tone…all with the Qboost.
