Liquid Mercury "Tap Tempo" PhaserVerified
Based on the Liquid Mercury "Tap Tempo" Phaser
From the post
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.
This is a great project by David Rolo from Madbean's forum
(check his website here: http://www.davidrolo.com/)

Thanks to Hozy31 for verifying this one!
