This amp has famous metal tones for a reason and probably the most aggressive among the all ENGL amps. It's well compressed and saturated, preserves its good high gain tones at lower volumes. Low end and highs are good to go, maybe it could have stronger mids but it has its own thing going on. Good when it's boosted, also good when it's not boosted, all up to your taste and style. It reacts perfectly to the palm mutes. Cleans are surprisingly nice for a high gain metal amp. It has cool features like built-in noise gate, mid boost, power tube monitor etc.
Cons: Shared eq as others mentioned. Got 4 stars because of that. For more versatility check Powerball II, it has similar voicing (but not same)
Few suggestions: It may sound harsh in the beginning with the new cab and stuff, as the tubes are fresh and the speakers need to be softened. Try with older cabs if it's possible. Cranking the volume and all EQ up would help for speakers to open up. For better lower volumes pass 12 o'clock with the lead volume and keep the master volume down to your limits. Don't be afraid to use eq knobs in extreme settings. Adjust presence again when the volume level has changed.
