Engl amplifiers have a long legacy of well-loved, precise-sounding, high-gain amplifiers. So when they set out to make the most flexible amp for metal and hard rock, they had to beat their already incredible line up. They achieved it in the 4-channel Powerball. While displaying all the thick, powerful punch and crunch that the brand’s built their name on, the Powerball also allows metal players to find equally inspiring shades throughout the gain range. If players are looking for a great metal amp with a ton of options under the hood, the Powerball is the place to start.

Never ones to ignore a classic design, Synergy reached out to the Engl Amp designer of the Powerball head, Horst Langer to provide us with the amp’s signature swath of tones in an all-tube Synergy preamp module. The Synergy Powerball module boasts two of the amps four channels with enough control on tap to go toe to toe with the namesake head. Not only will you find the standard 3-band EQ, gain, and volume controls, but two Gain Lo/Hi and Mid Boost switches per channel put a world of these German-engineered tones at your fingertips.
