This DSM Humboldt Simplifier X was purchased in March 2026. It has been used lightly, never gigged, and is in excellent condition. It does not come with any of the original packaging, but all features work as well as they did the day I got it, and there are no signs of wear and tear.

The following product description is taken from the DSM Humboldt site:

RESEARCH. DESIGN. IMPROVE. The SIMPLIFIER X was thoroughly designed and developed to fulfill the needs of guitarists seeking for versatility, flexibility, practicality and of course, the ability to get the best tones ever produced by analog gear.

NO MENU DIVING. ZERO LATENCY. ULTRA REALISTIC SOUND AND FEEL. WHAT YOU SEE IS WHAT YOU GET.

UNPRECEDENTED ULTRA CONNECTIVITY PLATFORM - True stereo (Two independent inputs) 3 different useful modes - No extra Y cables needed Dual FX Sends/Returns - THRU jack for dedicated DRY AMP signal path - 1/4 Outputs with Cabsim bypass - Two XLR DI outputs

MORE IS MORE: THE MODES 1. A/B AMP + A/B CAB This mode is dual mono, like having two different complete amplifiers, selecting each one with an A/B switch. Each amp will have their own preamp, power, cabinet, reverb mix and Loop FX. You can have different FX on each loop and select them by changing the channel. 2: A/B AMP + Stereo CAB In this mode, you can toggle between amp A and B Amplifiers, while the Cabinets and FX loop will remain Left and Right. This allows you to use different FX and cabinets for each side, expanding the stereo options and complimenting the responses of the cabs for a fuller, 3D sound. 3: FULL PARALLEL Full Parallel mode is like having two different amplifiers running at the same time. You can have different settings and effects for each side and make the perfect setup for a full stereo rig.  You can even use different effects at the input of each amp.

MULTI-STAGE STEREO REVERB
Includes a full stereo reverb, with mix control for each channel independently. 3 reverb modes: Short (ROOM STYLE), Mid (PLATE STYLE), Long (ETHER STYLE)
