The Lounsberry Pedals Organ Grinder is a preamp overdrive built for keyboards. according to RockBoard's PedalPedia, it was the first Lounsberry Pedal designed for keyboards, and it was developed with the aid of Roger Powell of Utopia and Meat Loaf fame1. Pedal of the Day, reviewing it in November 2023, describes it as a gain staged preamp with Germanium diodes that provides a fat, tubelike overdrive for clonewheel organs2.
Although it was designed with organ and keys in mind, it has been tested with guitar and bass. Pedal of the Day's reviewer found it rips with both: "As it easily handles the low notes, the Organ Grinder Overdrive also sounds awesome with bass guitar"2.
What it does to your sound
Pedal of the Day describes the drive character as gradual: "The onset of overdrive is gradual, adding compression and 2nd order harmonics"2. Second order harmonics are the even-order components often associated with a warmer, more tube-like break-up, which lines up with the maker's keyboard-first intent for the pedal. The same review notes that "With it's drive and transparency, it works extremely well even with complex chord shapes," a useful trait for keyboard voicings and for guitarists who play fuller chords2.
Controls
The Organ Grinder keeps things simple with two knobs2. As the reviewer put it:
"Sometimes two knobs, a great circuit and perfect gain staging is all you need to push your amp and tone right into that"
Where it came from
Lounsberry Pedals credits the Organ Grinder as the first of its pedals designed for keyboards, developed with the aid of Roger Powell of Utopia and Meat Loaf fame1. The maker's other pedals include the Gear Grinder1. Players comparing keyboard-friendly drive with guitar-oriented designs can also see how it sits among overdrive pedals generally, or against preamp pedals as a category.
