Since acquiring the AXE FX Ultra I'm becoming a bit more educated on guitar amps. So this is the question I just can't understand yet.
If the preamp is the key to tone and the power amp is intended to be transparent and boost the output, what is going on with the Mcintosh brand power amp which gets you to the signature Garcia tone?
When you hear folks talking about linear and ultra linear what are the talking about?
On that topic what are the options for Macs? I notice some units are ridiculously expensive while others are quite reasonable. Were any designed for guitar amplification or was it some sort of happy accident that the Dead stumbled upon this particular configuration?
Let me ask this another way. If you were to take the SMS Classic and run it through two equal power amps, one being a Carvin just as an example and the other being a similar output rated Mcintosh - what would be the sonic difference? It it in the EQ, or in the clean headroom?
The limitation, (if there is such a thing with the fractal) is it simply does not give options for power amps. It's all focused on preamps and does an excellent job at that.
