Re: Can this be the one amp that does it all ?

Just for reference, high voltage does not require heavy iron in the
transformer. I have electrostatic speakers with voltage multipliers running
off a wall wart which generates over 3000Volts but almost no current. High
current (power amp) requires the weight.

On Sweetwater's site, it says:
"120-watt Guitar Amp with Tube Preamp, MOSFET Power Amp,
Reconfigurable Circuitry, On-board Effects, and 12" Speaker"

And it lists the weight as 25 lbs. Wow!

Plus the rear panel pic on Mackie's site shows two very tubelike
silver thingies on the right hand side.

It might have a starved-tube preamp, which has been a popular
marketing scam for the past decade or so. They run a 12AX7 at a very
low voltage and call it "tube tone". It's lightweight because there's
no heavy transformer to produce the high voltage that most amp tubes
prefer to run at. A few starved-tube boxes I've heard sounded decent,
but they didn't sound like tube amps.
