Here are a few suggestions for where to place the MXR Phase 90 in your pedal chain
The placement of the MXR Phase 90 on a pedalboard can depend on personal preference and the specific effects chain being used. Here are a few suggestions for where to place the Phase 90 on a pedalboard:
Early in the signal chain: Placing the Phase 90 early in the signal chain, immediately after the guitar, can produce a more pronounced phaser effect. This is because the phasing effect is applied to the clean guitar signal before any other effects are added.
After a compressor: If you use a compressor pedal, placing the Phase 90 after it can help to smooth out the phaser effect and make it sound more natural.
Before delay and reverb: Placing the Phase 90 before delay and reverb effects can help to create a more atmospheric, swirling sound. This is because the phasing effect is applied to the clean guitar signal before it is processed by the time-based effects.
After distortion and overdrive: Placing the Phase 90 after distortion and overdrive effects can produce a more saturated, full-bodied phaser sound. This is because the distortion and overdrive effects add harmonic content to the guitar signal, which is then phasered by the Phase 90.
Ultimately, the best placement for the MXR Phase 90 on your pedalboard will depend on your individual preferences and the specific sound you are trying to achieve. Experiment with different placements to find the setup that works best for you.
What is the difference between MXR Phase 90 block and script?
The MXR Phase 90 Script refers to the original version of the pedal that was produced in the 1970s. This version featured a script logo on the casing and had a slightly different circuit design than the later models. The script version had a flatter frequency response and a more transparent tone and, a slightly different phasing sound than the later models. It is considered by many to have a warmer, more organic sound that is particularly well-suited for classic rock and blues.
The modern MXR Phase 90, on the other hand, features a different circuit design than the script version (4-stage phaser with feedback/resonance). This version has a a more pronounced midrange. It has a slightly smoother phasing sound and is particularly well-suited for modern rock and pop styles.
In terms of operation, the MXR Phase 90 and the MXR Phase 90 Script are virtually identical. They both have the same simple one-knob design that controls the speed of the phasing effect. They are both built with the same high-quality materials and are designed to be durable and roadworthy.
Ultimately, the choice between the two pedals comes down to personal preference and the musical style you are playing. If you are looking for a classic, vintage sound that is well-suited for classic rock and blues, the MXR Phase 90 Script may be the better choice. If you are looking for a more modern sound that is well-suited for modern rock and pop styles, the MXR Phase 90 block may be the better choice.
