Premier Guitar – following is the essential info in a recent review of the Powerball done by Premier Guitar and a link to view the full review.
Versatile & Heavy-Duty
“When I first opened the box containing this amp I could not help but notice the heavy-duty industrial look of the unit, with its chrome-plated front panel and screen grille. It is easy to typecast amps as being one-dimensional simply by their looks, but nothing could be farther from the truth here. It is, in fact, one of the most versatile amps I have seen...”
Clean & Loud
“When I first fired up the unit through a 4x12 cabinet with Celestion Vintage 30s, the Engl was set on the clean channel. I was very surprised to find a clean, warm, sparkling tone - very reminiscent of an old Voc AC30. This even sent me running for the electric 12 string, to see if it could do the Tom Petty or Jimmy Page thing, and with a couple of tweaks, the Powerball nailed it. Right then I knew I was not dealing with just another heavy rock/metal amp with little consideration for clean tones.....”
“In a word, the lead channel is massive; with the available control of the low end as well as the open/focused controls, you can dial in the biggest, tightest low end around, especially for detuned modern rock/metal. No matter how far down I detuned my guitar, I was still able to retain definition and clarity of the note...”
“In conclusion I would say that this amp is even more than it is advertised to be. I could easily make an entire album with this one amp head rock, metal, blues, jazz, fusion, funk, and even country and produce excellent results. It is a great value and I would recommend it highly.”
