The MXR Phase 90 is one of the most iconic phaser pedals ever made. Introduced by MXR in 1972 as the company's first product, it quickly became a defining sound of 1970s rock and remains in production to this day under the Jim Dunlop brand. The Phase 90 delivers a lush, organic four-stage phasing effect that adds movement, depth, and dimension to clean passages, chord work, and lead lines alike. Its single speed control sets the rate of the sweep, from slow, watery undulations reminiscent of classic studio recordings to fast, swirling modulation with a strong sense of motion. The pedal's simplicity is a large part of its appeal: no unnecessary controls stand between the player and the effect, and the phase character sits naturally in the mix without overpowering the core tone. The Phase 90 excels in combination with a mildly overdriven amp, where it produces a warm, breathing quality that has graced countless recordings. This unit has been tested and serviced and functions as intended. Confirmed users of the MXR Phase 90 include Eddie Van Halen (Van Halen), David Gilmour (Pink Floyd), and Jimmy Page (Led Zeppelin).

Ibanez TS80845TH Tube Screamer (s/n 1572, Limited Edition Sapphire Blue Sparkle)
As an amateur, fitting in the Boss SD-1 Super Overdrive is complicated. With the POD 2.0 alone there are so many variables, and more so with the SD-1. To play along with Tool's 'Pneuma' took me 10 minutes to arrive at the right sounds, sort of. The SD-1 is a less powerful apparatus than I expected, but in time we will be friends I guess.

DS Custom Octave Blender Octave Fuzz (Prescription Electronics C.O.B. Clone)
Great volume pedal for the price, I use it as a CV volume control on my Crumar Mojo and it has a nice feel and throw for hammond organ. Works great for guitar as well!

Ik wilde een Fuzz pedaal waar je clean en Fuzz goed kon blenden en waar dat goed reageert op een beetje push van een overdrive. Voor mijn bluesbandje wil ik wat meer keuze aan sounds hebben. Helemaal te gek deze Mythos. Besteld en twee dagen later in huis zodat ik een beetje kon jammen….top service!

Produkt visueel en technisch zoals omschreven. Netjes verpakt ontvangen bovendien. En het werkt allemaal prima.
Roel V. 5/5 Verified
Eerlijk advies en zelfs in het weekend goed bereikbaar voor vragen. De pedaal biedt kwaliteit en is zelfs beter dan verwacht. Heel tevreden.
Marco K. 5/5 Verified
Mooie wah/fuzz , klinkt meer dan prima . Het enige nadeel is dat je de fuzz niet apart kunt gebruiken en de volgorde wah/fuzz of fuzz/wah niet kunt omschakelen . Is voor de rest ook geen probleem , maar het was mooi geweest als het kon .

Fijn pedaal voor een goede prijs. Zeer vriendelijk geholpen.

Boss pedaaltje werkt prima, is schoon en ziet er verder nog netjes uit. Prijs/kwaliteit is goed. De bezorging duurde wat langer dan normaal (pinksterdagen en postnl die druk is) maar daar kan GuitarFX weinig aan doen. Verder geen klachten :-) m.v.g. Peter
