The Vary-Boost is an enhanced version of the VarioBoost, a boost/pre-amp pedal that has been discontinued for a while. It allows you to boost or cut any frequency ranging from 70Hz to 1400Hz. If you enjoy the sound of your Tube Screamer but find the mid-range emphasis to be too pronounced, the Vary-Boost enables you to reduce that frequency range. Similarly, if your Eternity pedal sounds too bright, you can easily attenuate the top end using this pedal. Previously, a minor modification was required to achieve this functionality, but that issue has now been resolved.
