Engl E 670FE-6L6 Founders Edition

Founders Edition: an iconic Special Edition in the ENGL universe

With the E670FE Special Edition Founders Edition, ENGL showcases its historic expertise: a fully tube design, handmade in Germany, and a philosophy focused on performance, precision, and versatility. This "Founders Edition" stands as a highly refined edition, designed to push the standards of high-gain tone even further, while preserving the ENGL DNA: sharp attack, tight low end, and surgical definition even at high gain levels.

The look is no less impressive: black finish, chrome knobs, and red illumination with a bold character, perfectly in line with the identity of heads built for heavy riffs and singing leads.

Who is the E670FE made for and in what contexts?

This 100 W head is primarily aimed at intermediate to advanced guitarists who want an ultra-complete platform: a truly usable clean, punchy crunch tones, and multiple saturation stages to go from ultra-tight rhythm riffs to thicker, sustained solos. In rehearsal, it maintains headroom and excellent clarity. On stage, it delivers the projection and authority typical of a large tube head, with practical control via footswitch and MIDI.

In terms of styles, the E670FE excels in hard rock, metal (modern, prog, thrash, death), but remains credible in rock and more nuanced genres when you utilize its Clean and Crunch channels, as well as the precision of its EQ.

Channels, routing, and control: a head designed for complex rigs

The E670FE offers five distinct channels (Clean, Crunch, Lead I, Lead II, Tubedriver) to multiply textures without relying on an overly heavy pedal chain. The saturations are designed to stay defined, with a fast response and excellent note separation, particularly appreciated in low tunings and palm-muted playing.

For effects, ENGL integrates three tube effects loops : a Serial FX Loop, plus FX Loop I and FX Loop II, each variable from series to parallel. This is a real advantage for finely balancing the mix of a delay or reverb in parallel, while retaining the attack and punch of the direct signal. The built-in noise gate (with footswitchable threshold ) helps maintain clean silence between attacks, essential for high-gain settings.

Finally, the head is ready for advanced integration: MIDI In / MIDI Thru, S.A.C port, and Dual footswitch input. The power tube monitor provides appreciated peace of mind for tracking and maintenance.

The sound

Fully tube, the E670FE offers a lively touch and natural compression that make playing expressive, whether you're strumming rhythm with a pick or playing lead. The Clean channel aims for clarity and openness, while the Lead channels push toward dense, precise, and highly controlled saturation, with tight low end and crisp attack.

The amp accepts either 4 x 6L6 power tubes or 4 x EL34 power tubes, allowing you to shape the response: 6L6s are often sought for their solid low end and a wider sound, while EL34s tend to emphasize more biting mids and a more "rock" feel in the attack. In both cases, the signature remains focused on definition and articulation, ideal for modern saturations and fast riffs.
