Woodbrass GE20 MFX

A Modeling Combo Designed for the Self-Sufficient Guitarist

The GE20MFX brings together the essential tools for exploring electric guitar in a compact format, without the need for multiple pedals and external devices. Its modeling approach lets you quickly switch from a clean sound to dense distortion, while its accompaniment features turn every session into a true musical playground.

Far more than just a small guitar amp, it combines an effects section, a drum machine, a looper and modern connections. This versatility makes it an especially appealing solution for developing your playing, working on your timing and developing song ideas at home.

For Improving, Practicing and Letting Your Ideas Speak

With its direct controls and numerous built-in tools, the GE20MFX is aimed at beginner guitarists who want to discover the main sound families, as well as more advanced musicians looking for a complete practice amp. It is suitable for daily practice, warming up before a rehearsal or preparing guitar parts.

The eight models cover a broad range of styles: pop, blues, classic rock, hard rock, fusion, progressive rock and metal. The drum machine helps you work on consistency, while the looper lets you layer chords, riffs, melodies and solos. Thanks to its headphone output with loudspeaker simulation, it is also well suited to silent practice sessions.

Modeling, Stackable Effects and Built-In Creative Tools

The model selector provides access to eight amp characters: CLEAN, OD.1, OD.2, DIST.1, DIST.2, MODERN, METAL and EXTREME. The organization progresses from clean sounds to the highest level of saturation. Each model has its own response in terms of texture and tone, allowing you to quickly adapt the amp to the desired style.

The GAIN control adjusts the amount of overdrive or distortion, while the tone control lets you boost the highs for greater presence. The master volume controls the combo's output level. This deliberately simple interface makes quick adjustments easy, even for a guitarist discovering modeling for the first time.

The effects section offers delay, reverb, chorus, flanger, vibrato and wah-wah. The effects from both sections can be combined, for example a reverb with a chorus, or a delay with a flanger. The Delay Time control adjusts the spacing between repeats, allowing you to go from a tight echo to more widely spaced repetitions.

The built-in drum machine features 40 accompaniments divided into eight style groups, with an adjustable tempo from 30 to 210 beats per minute. The 60-second looper supports an unlimited number of overdubs: record a chord progression, add a riff, then improvise over it. The included footswitch naturally makes it easier to control the looper while playing.

From Crystal-Clear Clean Tones to Modern, Cutting Distortion

Based on 24-bit / 44.1 kHz digital processing, the GE20MFX offers an extensive tonal palette in a compact format. The CLEAN model is ideal for arpeggios, open chords and clean sounds enhanced with reverb or chorus. The OD.1 and OD.2 settings add warmth and bite for blues, vintage rock or crunchy rhythm parts.

The DIST.1 and DIST.2 models increase density and attack for heavy rock and hard rock. MODERN is designed for more precise, contemporary textures, particularly suited to fusion and progressive riffs. Finally, METAL and EXTREME deliver a higher level of gain, designed for heavy riffs, palm mutes and heavily saturated solos.

The 16.5 cm loudspeaker delivers a direct, practical sound for personal practice. To play along with backing tracks, the wireless connection and auxiliary input make it easy to stream music through the amp. The line output also allows you to connect to external equipment.
