No compromise amp designed with John Mayer
The J-MOD 100 amplifier was intimately designed by Paul Reed Smith, Doug Sewell, and John Mayer to not only handle Mayer’s live work with Dead & Company, but to also move seamlessly into recording and performing with Mayer’s solo work. With a thoughtful control platform, impeccable build, and high-quality components, the J-MOD 100 is a fully-realized, high-end piece of audio gear for players who want the purest and most expressive musical experience.

Thoughtful control platform and feature selection
The J-MOD 100 amplifier is a single channel amp featuring a switchable gain stage and effects loop. The amp’s tone stack features a beautiful, spread out tone that is at once huge and clear. When the gain stage is kicked in, the amp gets rich in harmonics and delivers a bit more bite. The versatility provided by this setup allows the J-MOD 100 to deliver a huge variety of sounds whether using singlecoils or humbuckers.
Additional tone-sculpting features include a bright switch, which adds more high-end to your tone, and a presence control that boosts the high-end in the power amp section of the amplifier, giving you a livelier, more complex tone. There is no reverb built into the J-MOD 100, but an effects loop was requested by Mayer for his reverb tanks. The amp’s effects loop (and gain boost) is controlled by the footswitch, so players can use any reverb or effects unit desired with this amp.

Elegant and Robust Construction
The J-MOD 100 amp features five separate boards, all with over-sized traces for tonal integrity. Each board is dedicated to a particular part of the circuit: preamp section, power section, front panel controls, bias jacks, and the effects loop. Not only is this an elegant way to build with fewer long wires extending across a larger board, it is also a more robust way to build as there is not a single, large board that needs to flex during transport. The amp is hand-wired at PRS in Maryland, USA with a truly artistic level of craftsmanship. The J-MOD 100 also features a “laydown-style” power transformer for build integrity.

High-Quality Components
The J-MOD 100 pairs hand-crafted construction with top-of-the-line components, including a Cinemag output transformer and high-end capacitors in the preamp section. The result is authentic vintage tone with rich harmonics that sit at the player’s fingertips for a thoroughly expressive and transparent musical experience.
Built with serviceability in mind.

Mains fuse, B+ fuse, and bias adjustment jacks are accessible on the back panel of the amp, so changes and adjustments can be made without needing to open up the amplifier. In addition, the amp will accept many different power tubes types, including EL34, 6CA7, KT77 (with re-bias).
