Big things come in small packages, and the ENGL Ironball proves it! This compact, all-tube amp packs a serious punch with 20 watts of pure tube power. But when you need to dial it down, the built-in Power Soak lets you reduce the output to 1 watt—or even mute the speaker entirely—making it perfect for late-night recording or silent practice with headphones. The frequency-corrected line output ensures studio-quality direct recording, while the footswitchable Master Volume Boost (M.V.B.) gives you a second master volume for effortless dynamic control. With a Presence knob for fine-tuning your high end and built-in reverb for added depth, the Ironball is ready to deliver massive tone, whether you’re on stage, in the studio, or jamming at home.
