Here is what Hughes & Kettner say about the Grand Meister...
'GrandMeister has everything there is to love about all-analog tube amps and then some. Featuring onboard effects and Smart Rotary Controls in place of conventional potentiometers, it delivers real tube tone that you can program as you see fit.
Imagine storing and recalling 128 presets to squeeze every drop of tone from four amazing tube channels. With three onboard effects in studio quality. At the touch of a button.

And if that's not enough to get your pulse racing, imagine tweaking and controlling your tone in real-time with an iPad or standard expression pedals. How can something that feels so familiar be such a radical departure? Welcome to an entirely new way of expressing yourself.
