KR Musical Products is a boutique guitar effects builder founded by Kevin Randall, specializing in hand-built pedals that recreate the sounds of late-1960s vintage circuits. The lineup centers on Hendrix-era tones, with the Megavibe modeled on the Univox Uni-Vibe, The Doubler aimed at the octave-fuzz territory of the Tycobrahe Octavia, and additional fuzzes including the Fuzz Child and The Gypsy Fuzz. The line also includes The Tremolo and The Boost.

The pedals are recognizable for their purple enclosures and are built in heavy-duty aluminum chassis with true-bypass metal footswitches, Switchcraft chassis-mounted jacks, Alpha pots, and vintage-style components. Beyond effects, the brand has explored small tube amplifiers based on classic vintage designs and vintage-voiced Stratocaster-style pickups.

KR Musical Products has 4 products cataloged on Equipboard, including Fuzz Effects Pedals and Harmonizer & Octave Effects Pedals.
