Thanks to Hozy31 for verifying it!

Liquid Mercury "Tap Tempo" Phaser

I know this layout size breaks the basic rules of this blog but we don't have many Tap Tempo projects and
this pedal (together with the Twin Peaks Tap Tremolo) sounds incredible.
I think they both would be a great addition to the website's library.
