JHS Ross Compressor

Introducing a new era of ROSS pedals, meticulously crafted after extensive research and design efforts. This pedal embodies the captivating story, esteemed legacy, and iconic sound that have made the original ROSS brand a timeless favorite among guitarists and collectors worldwide. Offering five classic ROSS circuits, this series caters to every player's preferences. Each pedal is expertly manufactured at the JHS Pedals facility in Kansas City, MO, featuring the same stringent quality standards that have earned your trust.

Notably, these pedals come with several improvements compared to their vintage counterparts. They boast a soft-touch bypass, reduced noise levels, and a mode switch with two settings for enhanced versatility.

One of the highlights of this series is the ROSS Compressor, an OTA-based, vintage-style compressor faithfully replicating the sought-after "Era 2" Gray Box ROSS Compressor circuit. Regarded as one of the most legendary and highly praised compressors of its kind, we are thrilled to bring this design into the modern age.


“Level” controls the volume (right is louder, left is quieter). “Sustain” controls the amount of compression/sustain (right is more compressed/sustained, left is less compressed/sustained). When activated, the side push switch toggles between two modes: Standard and Bright. The Bright mode helps your guitar cut through the mix when you need a little extra clarity for darker pickups or amplifiers. The footswitch activates the pedal via soft touch bypass switching and the status LED indicates that the circuit is active.


The ¼” input and output jacks connect your guitar and amplifier. The power jack accepts standard 9V DC Negative Center power and consumes 37mA.
