The Analog Man Beano Boost Pedal is a boost pedal based on the 1960s British Dallas Rangemaster, which was needed at the time to give a treble boost to the dark British amps. This allowed them to get a sound more in tune with the time, as guitars were starting to become a loud, bold, lead instrument. This effect pedal is a type of BOOSTER, not really a distortion pedal nor a clean boost- it does modify your sound quite a bit. It excites certain frequencies and pushes your amp to allow it to create rich tube distortion. The pedal colors your tone, with a crunchy overdrive, boosting certain frequencies, and warming the tone with NOS germanium transistors. It does not have a lot of compression and sustain like most OD pedals, but a more raw, open sound. This pedal has three tone settings from the tone switch- Center is a treble boost, the same as the original Dallas Rangemaster. UP is a fuller-frequency mid range boost (MID setting). Down is a LOW range, also quite a full frequency sound. The Beano Boost is spectacular into an amp that is already cranked up pretty well. It will also work well into a clean amp, but you probably need to turn the volume on the pedal up, to make the tone thicker by hitting the amp harder and making it work more.
