Monoprice is an American online electronics retailer founded in 2002 by Jong Lee and headquartered in Rancho Cucamonga, California. Originally known for selling affordable cables and adapters direct to consumers, the company has expanded into a wide range of product categories including musical instruments, pro audio equipment, and audiophile-grade home audio. Monoprice markets its music and audio products under distinct sub-brands: Indio by Monoprice covers electric guitars, basses, and effect pedals, while Stage Right by Monoprice encompasses guitar amplifiers, condenser microphones, stage lighting, and other pro audio gear.

The Indio guitar line includes budget-friendly models like the Retro Classic and Cali series as well as higher-end DLX and DLX Plus instruments featuring premium tonewoods such as mahogany, alder, and ash. The Boardwalk series offers semi-hollow body guitars in the "335" style. Indio effect pedals feature true bypass switching and all-metal enclosures. On the amplifier side, Stage Right produces tube combo amps with Celestion speakers, including a popular 15-watt 1x12 model with spring reverb and a compact 5-watt 1x8 practice amp. Stage Right also offers the LTM500 multi-pattern tube condenser microphone and pencil condensers aimed at home studios and project recording setups.

Monoprice's approach to musical instruments and pro audio mirrors its broader business philosophy: offering functional, no-frills gear at price points well below established competitors. Their guitars typically retail between $100 and $250, and their tube amplifiers and microphones follow the same aggressive value positioning. The brand has a following among budget-conscious musicians and beginners looking for playable instruments without a significant financial commitment.

Monoprice has 46 products cataloged on Equipboard, including Solid Body Electric Guitars, MIDI Keyboard Controllers, and Combo Guitar Amplifiers. Their gear is featured by 5 artists, with the strongest followings in Rock, Hip Hop, and Electronic. Notable users include Dustin Kensrue, emma essex, and Elements of Music. Most Monoprice products sit on the budget-friendly end of the spectrum.
