KSR Amps (legally Rhodes Amplification, LLC) is a high-gain guitar amplifier builder founded by Kyle Rhodes in 2009. The company began as a small custom shop in central Indiana doing one-off builds and modifications for local musicians, released its first standard production models in 2011, and later relocated its workshop to the Cincinnati, Ohio area. The brand was originally known as Rhodes Amplification and rebranded to KSR (Kyle's initials) to avoid trademark conflict with the Rhodes keyboard name.

The lineup centers on hand-built tube heads aimed at the metal and high-gain market, including full-size models like the Juno, Orthos, Gemini, Artemis, and Colossus, alongside lunchbox-format heads such as the Ares 50 and Orion 45. KSR also produces matching guitar cabinets (RCS series in 1x12, 2x12, and 4x12 configurations), rackmount and compact tube power amps (PA-50R, PA-100R, PA50), and a line of preamp and boost pedals including the Ceres, Ceres ONE, Vesta, Eros, and Hera, plus the EX5 MIDI interface.

Amps and components are built in-house in a small U.S. shop, and the brand has developed a reputation in online guitar communities for tight, articulate high-gain tone and point-to-point or hybrid construction. European and UK distribution of the effects pedals is handled by Audio Distribution Group.

KSR Amps has 7 products cataloged on Equipboard, including Guitar Amplifier Heads, Overdrive Effects Pedals, and Combo Guitar Amplifiers. Their gear is featured by 2 artists, with the strongest followings in Rock. Notable users include Joe Satriani and Dan Sugarman.
