WooHoo!
My VH4 is here! I'm still waiting on the cab to go with it, but for now I can slum it with my Orange 4x12 v30 loaded.
Sounds AWSOME. Really BIG and FULL sounding, very detailed. 4 channels of goodness.
1) Clean pretty much all the way up, pretty dark I suppose, but the bright switch fixes that if you need to!
2) Overdriven. Starts where 1 leaves of and goes up to a good crunch tone. Also has a bright switch.
3) This is very similar to my Orange Rockerverb dirt channel, nice and open, good classic rock sounds. British voicing I'd say.
4) High gain, this is a modern sounding compressed channel, american voicing, superb for your chunky metal requirements.
Each channel has it's own volume, gain, bass, mid and treble controls, plus the amp has a master volume, presence and deep control. The master volume control works well, but the amp seems to open up a bit more at room levels if I up the master a bit and then bring in the hotplate at -8ohms. Need to play with this more.
Haven't even scratched the surface yet, but I'm failing to see why I'd need another amp. (please note I didn't say i wouldn't want another amp, I just won't need one.)
Can't wait to get the cab now!
