Electro-Harmonix ABRAMS100 100W Guitar Amp Head - Yellow

Delivering 100 watts of clean, dynamic guitar tone from a head that weighs just 2.5 pounds, the Electro-Harmonix ABRAMS100 challenges expectations of what a portable amp can deliver. Built for players who need headroom, clarity and full-bodied response in a compact format, this ultra-light Class-D amp head moves effortlessly from whisper-quiet passages to harmonically rich drive. Its high-headroom analog frontend preserves the natural feel of your instrument, while a three-band EQ with bright switch makes it easy to shape sparkle, presence or warmth across different cabinets. Built-in digital spring reverb adds depth and dimension, and a flexible FX loop supports seamless integration with pedals and modelers. Compact, powerful and adaptable, the ABRAMS100 is designed for stage, studio and everyday playing.

High-Headroom Analog Frontend With Touch-Sensitive Response

At the core of the ABRAMS100 is a high-headroom analog frontend voiced for clean articulation and musical feel. Increasing the gain does more than add volume, introducing subtle harmonic richness and natural breakup that responds directly to playing dynamics. The three-band EQ provides precise control over lows, mids and highs, while the bright switch adds clarity and presence for darker cabinets or lower-volume settings. Whether running a straight guitar signal, pedals or a modeler, the ABRAMS100 maintains clarity and responsiveness without flattening dynamics.

Flexible FX Loop and Built-In Digital Spring Reverb

A series FX loop with a pre-master return allows pedals, external preamps and modelers to integrate cleanly into the signal path without unwanted level shifts. This layout keeps the amp balanced and responsive while offering flexible routing options for modern rigs. The onboard digital spring reverb adds classic warmth and space, supporting everything from subtle ambience to deeper wash. Together, these features make the ABRAMS100 easy to adapt to a wide range of setups without complicating the signal chain.

Ultra-Light Class-D Power for Modern Guitar Rigs

Designed for players who value portability without sacrificing performance, the Electro-Harmonix ABRAMS100 delivers serious power in a radically compact enclosure. Its 100 watts of Class-D output provide ample volume and authority for real-world stages, while the 4–16 ohm output ensures compatibility with a wide range of speaker cabinets. Ideal for pedalboard-based rigs, external preamps and modeling systems, the ABRAMS100 keeps control straightforward and tone intact. For fly dates, downsized stages or players seeking a clean, high-headroom platform, this ultra-light head proves that powerful guitar amplification does not need to be bulky or complex.
