Jerry Donahue

I meet Jerry with Peavey at Music Prolite & Sound in Frankfurt 2006. The Nobels ODR1 was his main overdrive pedal. His settings for the pedal you'll find on the picture.

On Mad Professor's website, Donahue was mentioned as user of this compressor pedal.

The new Radial Elevator is a pedal that successfully achieves what others were designed to do but never quite made the grade. This one enhances your overall sound with no discernible change in tone between normal and boosted outputs! After all the years of searching... no need to look further. This is it!

Donahue about Radial Elevator.

On Mad Professor's website, Donahue was listed as user of the Deep Blue Delay Pedal.

In the source link PDF, on the second page, you can see Jerry Donahue himself holding the Sessionmaster JD10 preamp in his hands. Jerry Donahue collaborated extensively with Stewart Ward (the founder of the company Award-Session) to develop the preamp to his liking and earning it as his signature pedal (JD in the model name stands for Jerry Donahue). Jerry Donahue used it for both studio session playing and recording work and live gigs across the globe, according to the official product manual.

Quoting Jerry Donahue from the official product manual:

"It's my... Guitar Amp Emulator, Humbucker Emulator, Amp Tone Expander, Overdrive, Recording PreAmp, Guitar Speaker Simulator, EQ/Tone Booster, Signal Booster... all in one great pedal!"
