Designed to work seamlessly with both bass and guitar, the Summer School Half Day is a modern, boutique take on the Ross-style compressor, an OTA-based, vintage-style compressor known for its fast yet smooth action.

A toggle switch changes the input capacitance allowing more bass-friendly frequencies for lower-tuned instruments like bass or baritone guitar, or cut them for regular six strings.

A tilt-EQ that does high- and low-pass filtering while remaining neutral at 12 o’clock.

The Half Day can also be used as a boost pedal thanks to the Volume knob, which can push your signal up during solo or other more intense song sections.
