Bridging the gap between the analog warmth of tube amps and the modern flexibility of digital technology, the ENGL E606SE Ironball Special Edition delivers uncompromising tone and versatility. Designed as a true all-tube head, this amp ensures pure, uncolored sound with zero semiconductors in the signal path. At its core, the E606SE features a two-channel design, each with boost functionality. The Clean channel produces sparkling, chime-like clarity, breaking up smoothly when pushed. Engage the gain boost, and it transforms into a rich, dynamic crunch tone. The Lead channel picks up where the Clean channel leaves off, packing a massive amount of gain for anything from classic rock to crushing metal. With an additional boost, it unlocks even more tonal aggression and versatility. While the preamp and power amp stay fully analog, digital components are seamlessly integrated for the MIDI system, effects section, and Impulse Response (IR) Loader, offering ultimate control and modern convenience. The built-in Power Soak allows you to drive the power amp into natural saturation at lower volumes—perfect for late-night practice or achieving full, harmonically rich tube tone without shaking the walls. Compact yet powerful, the ENGL E606SE Ironball Special Edition is the ideal amp for players who demand classic tube warmth with cutting-edge flexibility. 2 Channels: Clean, Lead All Tube Head Power Soak (Full Power / 20 Watts, 5 Watts, 1 Watt, Speaker Off) Tube buffered FX Loop Noise Gate Master Volume Boost (M.V.B.)
