Modifications

If you've ever said to yourself "Wow, this pedal sounds great but if only it had a little more bass." or "This would be perfect if it had a little more gain." A simple modification to a pedal could quite well be the answer to achieving the sound you're hearing in your head.

Below are the pedal modifications currently available; I will add more as I soon as I dream them up. If you've heard of an existing pedal modification you're interested in or have any questions about the modifications below, please contact me at mods@fantailaudio.com 

MXR Phase 90

MXR Phase 90 'Superscript' Mod
If you crave that classic Phase 90 tone from the 1970s but don't want to break the bank buying a vintage 'Script' logo version from that era, then the 'Superscript' mod is for you.

 

Probably the most common modification performed on the MXR Phase 90 (Model M-101) in order to replicate the vintage tone of a 'Script' logo Phase 90 tone would be the so-called 'R28' or 'Script' mod; in which the feedback resistor known as 'R28' is removed. The inclusion of this single component in later versions of the Phase 90 (featuring the 'Block' logo) made the phase-shifting effect this pedal was famous for much stronger and more pronounced at the expense of boosting and even causing distortion in the midrange.

MXR Phase 90 'Superscript' Mod

If you crave that classic Phase 90 tone from the 1970s but don't want to break the bank buying a vintage 'Script' logo version from that era, then the 'Superscript' mod is for you.

'Superscript' mod demo by Jason Herbert.

While this mod is simple to perform, removing R28 will only get you part of the way in terms of capturing that classic Phase 90 tone from the 1970s that so many guitarists crave.

The 'Superscript' mod overhauls the stock MXR Phase 90 circuit to be as close as possible both electronically and sonically to the original 'Script' circuit while working within the confines of the current production circuit boards.


In order to archive this, a total of 28 components are removed or replaced due to either being the wrong value/type of the component (sometimes both) or because they simply do not belong in the original circuit.  From the input stage to the power supply section, and everything in between. No stone has been left unturned in recreating that classic phase tone you know and love.

And the result, a more subtle, smoother phase tone that is more musical without any of the boosted or distorted midrange and the modern convenience of a status LED and DC power jack that the original 'Script' version and the current reissues lack.

Fantail Audio stands behind all of the modifications performed on each and every pedal. So much so, that if you experience any problems with the modification, simply let us know and we will make it right.
