Analog Mike compared this new pedal to the original 1974 Phase-90 on his pedalboard and found it's just as great sounding! So we are carrying them now and selling them stock or with some convenience mods.

The long-time standard among phasers, the MXR Phase 90 is on the list of many players and even more collectors. Carefully recreated, this famous effect is available once again as the 1974 Vintage Phase 90. Hand wiring and hand selected matching transistors work together to bring back the same mesmerizing, smooth modulation as the original. You'll even find the same classic orange painted metal housing with the script logo.

MXR effects have set the standard for tone and durability for more than 25 years. From time-honored classics to new cutting edge designs, MXR has your sound.

Phase in the sound of the past and change your tone's future.

The stock bypass tone is not bad, almost no measurable resistance or capacitance when OFF or audible change in tone. But there are quite a few reports of phase bleed-through when the pedal is OFF with the stock bypass. So we will offer true bypass mods on this pedal. The bypass mod is needed if you want to add an off/off status LED. Power jack option is cheaper if you get the bypass mod as the bypass mod will cover the labor for both. Or you can use the Z Vex power plate for powering the pedal through the battery clip without a power jack. You can put the power plate in the shopping cart from our Z Vex area.

Optional power jack will fit ABOVE or BELOW the INPUT or OUTPUT jack so let us know if you have a preference. Otherwise we will probably put it ABOVE the INPUT jack (on the right of the knob).

Volume Trimpot Option

Some people notice an apparent volume drop (or volume boost) when the Phase-90 is turned ON. It may be even worse with a true bypass mod, as the OFF sound will be totally clear and unchanged from what is seen at the input. We can add a small trimpot on the board so you can set the ON volume where you want it, even a little volume boost if desired.

The volume trimpot we add is in the corner of the board. The stock BIAS trimpot is near the switch. You can adjust the bias by ear while playing to get a smoother/mellower, or more pronounced Phase sound if you want:



MIX KNOB OPTION



We can add a small external MIX knob to the Phase-90 so you can set the mix between phased sound and dry sound. Exact stock setting and sound is 50%, with the knob at noon, there is a DETENT on the pot at that setting. This is the normal sound and the thickest/most effected as the vibrato mixes with the dry to make the phase cancellations. You can get a more subtle effect by turning it down, or more of a VIBRATO effect (not as intense of a sound) by turning it up. When turned from the stock 12:00 setting, the volume may go up, you can get it back down with the volume trimpot. So you should get both mods if you think you will change it much from the stock mix setting.

Note that the rubber knob cover may rub on the added knob.

BUFFER OPTION

The phase-90 has a high output impedance, so it cannot drive long cables, volume pedals, etc without losing volume and tone. So you should run something buffered after it, usually your delay pedal will be all you need if it's always on. If you don't have a buffered pedal after it, you should get our BUFFER option in which we add our buffer board in the battery compartment, and a power jack. See our BUFFER page for more info :

PHASE-45 TOGGLE OPTION

We can add a toggle switch to change the circuit into a milder, 2 stage phaser. One position is the normal phase-90 and the other is phase-45. The phase-45 changes your sound less and is a little closer to a uni-vibe sound. In Phase-45 mode, the FEEDBACK option does not function. There will be a POP when you switch the toggle, best to turn the pedal off if you need to change the mode during a session.

FEEDBACK KNOB

We can add a FEEDBACK KNOB to add more effect to the phase, especially the higher frequencies. We can't add too much or the pedal will squeal and whistle. If you have the VOLUME trimpot, be careful as increasing the volume may cause this loud squealing feedback at higher volume levels. The stock script logo FEEDBACK setting is all the way down. For the block logo sound, turn it up about half way. This does not work with the Phase45 toggle option position.

Note : Mod and option prices are cheaper when you buy the pedal from us, see mod form for prices on sending in your pedal for a mod. MOD FORM IS HERE
