The Skyscraper is an extremely versatile overdrive/booster pedal.
This pedal has completely independent overdrive and boost channels, with pre/post toggle switch placing the overdrive channel before or after the boost channel.
The overdrive channel is a medium gain OD and highly responsive to the guitar's volume.
The boost channel has a parametric mid equalizer. The range of the mid frequencies is 200Hz~2kHz and you can boost/cut them with 15db.
