Description
Unlock the limitless potential of your guitar tone with the DSM & Humboldt Electronics Simplifier DLX, an innovative zero-watt, dual-channel stereo amplifier that perfectly bridges classic sound with modern technology. Designed for musicians who crave boutique sound possibilities and portability, this amp and cabinet simulator offers an all-analog experience, enriched with multi-stage reverb and ultimate connectivity options, all within an incredibly compact design.
The Simplifier DLX features two fully independent studio-grade preamps capable of modeling iconic amplifier tones, giving you access to three preamp types (MS Brit, American, AC Brit) and three gain modes (Clean, Crunch, Lead) per channel. Channel A is optimized for aggressive and expressive playing, while Channel B delivers a warmer, rounder sound perfect for clean tones and blues crunch to heavy rock rhythms.
Its ultra-connectivity platform provides flexible use as a stereo 2-channel amplifier, two-parallel amplifiers, or for dual guitar use, each with its own amp and effects loop. With stereo FX send and return jacks, DI outputs, and 1/4-inch outputs, you can effortlessly integrate the Simplifier DLX into any setup, whether recording, performing, or practicing silently with its high-grade headphone amp.
The Simplifier DLX’s multi-stage stereo reverb enhances your soundscapes with three distinct modes: Room, Plate, and Ether, allowing independent mix control for each channel. Crafted with a robust aluminum chassis, this pedal is built to withstand the rigors of both studio and stage environments.
