The Caline CP-57 Summer Night is an analog distortion and equalizer pedal that, according to the maker, models the amp roar of a Mesa Boogie MK. Caline describes it as putting the early Mesa Boogie tone at your fingertips, with classic American style vintage high gain sounds that can be sculpted using six different controls. RockBoard's PedalPedia calls it very flexible and very loud.1
It can be used two ways: for direct recording into a computer, or placed in front of an amp to give your sound a new character. That makes it a candidate for players who want a high-gain preamp-style pedal that works both on a board and in a recording setup.1
What it does
The CP-57 is built around a model of an early Mesa Boogie MK amp's roar, in the classic American vintage high-gain style. Caline's product information describes the tone as sculptable with six different controls, which is more tone shaping than a typical three-knob distortion pedal offers, and the maker characterizes the pedal as very flexible and very loud.1
Because it is an analog circuit with an equalizer section built in, it sits in the same family as other Caline distortion-plus-EQ designs such as the Caline Easy Driver Distortion EQ. Players comparing options in this lane can also look at the Caline CP-27 White British Distortion, which points at a British-style high-gain voice rather than the CP-57's American one, or browse the wider range of Distortion Pedals.1
Power and setup
The CP-57 runs on 9V DC, center negative, and draws 50mA. That current draw is higher than many compact analog pedals, so it is worth checking against a daisy-chain supply's spare capacity before sharing a tap with other pedals.1
