Featuring true stereo capabilities housed within a single unit, the Roland JC-40 is a 40W 2×10″ combo amplifier designed to deliver a clean tone to an electric guitar. The unit features a three-band tone stack and a bright switch, as well as distortion, reverb, a special stereo chorus, and vibrato capability. A set of dual inputs can be used for stereo purposes, such as connecting a stereo-output effects unit or a guitar or synth with stereo output.

Turn your attention to the back of the amp and you’ll notice multiple options for connectivity: An effects loop (switchable between series and parallel) allow you to patch in stereo effects, while dual line outputs provide a convenient stereo feed into mixers, PAs, or recorders. You can achieve silent stereo for practicing using the 1/4″ headphone jack on the front panel.

With the addition of a footswitch (available separately) you can enable the onboard chorus, vibrato, reverb, and distortion settings at the tap of a toe.
