With so much processing power compared to previous models, Fractal could capture the entire hexaphonic guitar market by simply adding more Amp sim blocks - enough for one for each string.
There's already discussion of 3-Amps-At-Once being available, in another thread. The notion produced a fair bit of excitement and enthusiasm.
I grant that
three is not the same as
six. But depending on what you're trying to achieve (tonally), it might be enough.
Were the 3-Amps-At-Once to appear in an upcoming Firmware update, I would try running...
- Strings 1 & 4 into Amp 1,
- Strings 2 & 5 into Amp 2,
- Strings 3 & 6 into Amp 3,
...and testing out the interactions.
By doing so, I think you'd get an effect not-very-different from One-Amp-Per-String.
After all, it isn't an ultra-
clean amp that gives you a big difference between One-Amp-Per-String and All-Strings-Into-One-Amp.
On the contrary, it's the
distortion and intermodulation that makes the difference. When 2 notes play through the same distortion circuit, their overtones clash. The more distortion there is, the more that the notes themselves become harder to distinguish. And the effect is worse, the closer-in-pitch those two notes are. (Excluding unisons, of course.)
But if your 3rd and 6th strings share an amp, I don't think the overtone clash would be particularly bad. The notes are certain to fall in different octaves; often they'll have more than an octave
between them.
Certainly, with such an arrangement, any chord played on 3 adjacent strings would sound similar to the Boston-esque "guitar harmonies."
Is that what you were hoping to achieve?
