Condition Details
This Mesa/Boogie M-Pulse 600 Bass Amplifier is in very good overall condition. Fully functional and sounding excellent. Cosmetically, there are some signs of use including light surface wear to the faceplate, minor scuffs to the rack ears, and general marks consistent with rack mounting and transport. The rear panel shows some residue from a previous PAT label.

All controls, inputs, and outputs have been tested and are working as expected. No known faults.

Included Accessories

• Gator hard rack case (not Mesa-branded)
• Power cable

Mo Says…
This is one of those slightly under-the-radar Mesa pieces that bass players who know absolutely swear by. It’s got that classic Mesa authority: tight, punchy lows, loads of headroom, and a really musical EQ section that lets you sculpt without killing your tone.

The semi-parametric EQ is the real secret weapon here. You can dial this in for anything from super clean modern clarity to warm, driven tube character.

If you’re after a serious gigging or studio bass head that can cover basically any genre without breaking a sweat, this is a bargain.
