GRYPHON is thick and chewy, with a little bounce in the low end.
VEGA is lean and mean with some really nice thwack to the attack.
GNL is very similar to the Gryphon, just with more gain range and tighter lows.
I also had a HYDRA, and that channel was perfect for lead playing. Really juicy, liquid and compressed sounding. Didn't work for me as well as the others for tight rhythm and riffage though.
The Gryphon, Vega and GNL all respond beautifully to a TS-style boost.
And each has an addictive growling grind to their voicings.
Do you like your Vega? What cabs are you playing it through?
