IMO, the tone I like is very easy to dial in on this amp head. I use them 98.746% of the time. My other head is a GK MB500 fusion. And an old Acoustic 370 head.I suspect a product update will be coming. IMO that little head served a niche function in the market space for GK loyalists and has been a notable success in the compact, but capable class D world. I've enjoyed mine.
