The MXR Custom Shop Script Phase 90 Guitar Effects Pedal, has been painstakingly researched by the MXR Custom Shop team to ensure as faithful a recreation of the classic 70's model as possible. It is clear that they have succeeded in resurrecting the luxurious phasing of the original, whilst implementing some useful additions - LED indicator and 9-Volt power supply input/9-Volt battery compartment - to cater to the needs of today's guitarists.

Hand-wired circuitry

As noted already, the MXR Custom Shop team went all-out with their efforts when trying to capture the unique character of the MXR Phase 90. The hand-wired circuit board has been built with original spec components that match the 1975 model. The jacks are original high quality Switchcraft jacks, with a Carling bypass switch on duty to ensure noiseless activation.

Simple yet powerful control

The Script Phase 90 has one of the simplest control layouts you're ever going to find - a footswitch paired with a Speed knob. All you need to do to access the smooth 4-stage phasing within is plug in, power up, hit the switch, and dial in your desired rate of phase. Easy! Whether you want to go from a subtle shimmering shade or a sweeping, swirling wave of phase, all you have to do is turn the knob. Played clean you can get a sweet twang, whilst heavy distortion generates a powerful tsunami of sound. The extended headroom and clarity of the original circuitry means that the warmth and character of your guitar shines through in all its glory.

Taking just as much care with the finish as with the tone, the MXR Custom Shop Script Phase 90 Guitar Effects Pedal comes in an eye-catching smooth orange paint job with a heavily stylised script logo. The chassis is as tough as they come, so you can rest assured that this beauty can endure anything thrown its way whilst on tour or in the studio.
