ENGL Ironball Head

Compact Tube Amp Head with Four Channels and Integrated Power Soak

ENGL Ironball E606 is a four-channel tube amp head in a compact format, offering versatile functionality for both stage and studio use. With a 20-watt output that can be reduced via the built-in Power Soak, it is also suitable for low-volume practice and recording. The amp features four modes – Clean, Crunch, Soft Lead, and Heavy Lead – covering a wide range of tones from clean to high-gain.

Designed for Practice, Stage, and Studio

Thanks to the Power Soak, output can be reduced to 5 W, 1 W, or completely muted, allowing for headphone practice or silent recording. Two types of line outputs are available: one with cabinet simulation and one with a pure signal for external processing.

Flexible Control Options

The amp includes a tube-buffered serial FX loop, shared 3-band EQ, Master Volume Boost (M.V.B.), and a dedicated Presence control for the lead channels. With onboard reverb and compatibility with ENGL’s Z4 footswitch, the Ironball E606 adapts easily to a variety of performance and mixing environments.
