MXR CSP101SL Script Phase 90

The MXR CSP101SL Script Phase 90 takes its design and inspiration from the original version, that has achieved an iconic status amongst guitarists for its classic phase shifter sound that has appeared on many songs of the late 70s. This new model offers those same classic tones, as well as added warmth and a smooth phase. The CSP101SL also comes dressed in the same orange finish with a black script logo.

An Iconic Pedal

Based on the iconic pedal that played a big part in 1970s hard rock, jazz-fusion and funk, the Script Phase 90 offers that same classic tone and look. Featuring a hand-wired circuit board built with the original 1975 components, the Script Phase 90 delivers the same headroom and clarity of the original, as well as added warmth and smooth phasing. This powerful unit can be powered by one 9 volt battery or a power supply (sold separately).


Like the original, this new model also comes dressed in a vibrant orange chassis with a black script logo. Its basic design features one control knob for Speed, which also includes a textured edge, making it easy to adjust with your foot whilst playing. An LED indicator light is also incorporated and is ideal when lighting is poor. The durable metal chassis provides a roadworthy design, making the Script Phase 90 ideal for gigging musicians.
