J-MOD 100 Controls Walk-through | PRS Guitars

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.
