Product Details

The JM-1W is Rift's first low-wattage Lunchbox-style head

Don’t let its size fool you, this little 1-watter amp is no toy. Rift spent months perfecting the design to deliver a massive sound in a compact form, ideal for both the living room and the studio.

The JM-1W delivers rich, clean tones and gritty overdrive at conversation-level volumes. Coming in at roughly 12" x 6" x 9", this head features a single knob that functions as both volume and tone control. Set low, it’s bright and clean; turn it up, and it darkens as it compresses, overdrives, and eventually distorts.

The standout feature? An internal load with a post-output-transformer line out. That means JM-1W doubles as a killer preamp—plug it into another amp or straight into a recording console to get real power valve drive tones at any volume.
