Collecting x time = !!! My stash of Way Huge pedals by @jtripps... can you spot the pre-Dunlop, real-deal early '90s super rare units?

At 0:16 of this studio session by John, a Tycobrahe Octavia pedal can be seen at the middle, and end of his drawer.

This is the Pedal-Rig. I'm a collector

At least one of the three tuners you can see on his board is a TU-2

In this photo, John Mayer can be seen using a Line 6 DL4 Guitar Effects Pedal.

There is no "MKII" sign under the words Aqua-Puss on the blue Aqua-Puss pedal in the photo of John Mayer's board. The Dunlop reissue has "MKII" printed just below the far right of "Aqua-Puss." This is therefore an original Way Huge product, hand-built by Mr Jeorge Tripps between 1992-1999.

Heard this in the car today, wanted to try it out... Collings I-35 through a Roland Space Echo pedal, Cornish NG-2 Fuzz and Fender '64 Vibroverb... Looped through a Boomerang pedal.

The MXR M-108 Ten Band Graphic Equalizer Pedal is used by American Blues guitarist and singer John Mayer in his guitar pedalboard.
