We have a copy of the official Engl Powerball manual. You can view detailed information on all the switches and functions on the front panel. Included are tips from the designer of the amp on how to get the best tone possible.
You can also view a rear panel diagram detailing the built in noise gate, foot panel ports, FX loop, and power amp outputs.
Finally, Engl includes 5 sound sample setting diagrams showing you how to set up the amp to get Crystal Clear, Power Crunch, Ultra Scoop Metal, Infinite Pressure, and Liquid Lead tones.
