A four-channel, all-tube powered head, the Powerball offers sound-shaping options unrivalled by any other amp. Designed to satisfy the exacting demands of discerning players, it delivers all the tonal hues and colors you need to paint the most vivid musical pictures imaginable. Housed inside this newly designed enclosure is a powerhouse 100-watt amp boasting 6L6GC tubes. It delivers the sonic goods you need to dial in everything from contemporary ultra-high gain lead tone to crystal-clear clean and punchy crunch sounds. An astonishing amount of gain reserves, remarkable tonal versatility, and bone-rattling bottom end have crowned the Powerball king of the heap among modern-day guitar amps.

Courtesy of its ability to crank out tight, focused low end, glossy top end and jaw-dropping sound pressure levels, this amp provides the contemporary guitarist with richly detailed tone and the kind of cut-thru-the-din assertiveness that sets standards for amps of this class. And in keeping with the ENGL tradition of engineering excellence, it sports a host of hip features: a second master volume, electronic power amp monitoring, an adjustable FX loop, and a Depth Punch knob that shapes the power amp’s response by beefing up the low end. But that’s not the last word on this ENGL head’s innovative features: You also get two different sound voicings, Open and Focused. We created these voicings to extend the range of lead sounds you have at your disposal by tweaking mid-range response to suit different playing styles and applications.

There are few more handy features to rave about: The amp ships with a Z-5 Custom Footswitch Port. Designed to take the ENGL Z-5 footswitch that lets you control all key sound-shaping functions remotely. ENGL added another new audiophile wrinkle – an adjustable noise gate for the Lead channel. Old world craftsmanship and highest quality components are part of what makes ENGL amps so special, and the Powerball is no exception. On that note, please read and heed the guidelines on handling all-tube amps. You’ll find them on the last page of this manual. The ENGL team is convinced that this amp will delight and inspire you. The Powerball will rock your world!
