I have owned VHT/Fryette, Mesa, Marshall, etc. My Splawn has beaten all the know, higher end available production amps. I never thought I'd be happier than I was with my VHT/Fruette's but man the Splawn just absolutely KILLS!
Henning, Friedman, etc. are all amazingly built amps and I am sure will yield you the results you are looking for but value for dollar, (which is relative to the buyer) no one beats Splawn's offerings IMHO.
My favorite tones are old Dokken, Ratt as well as Accept, Maiden, King Diamond all the way up to In Flames. The Splawn Quick Rod will nail all of them.
Steve, plaease understand my statement as this, I would LOVE to buy a Henning. No doubt, and one day I may (actually looking to buy myself a nice 40th birthday present in Sept). Generally folks that want to spend Cameron, Henning, Rhodes money will not add lower price point offerings in their posts which tells me the real question was, will the Splawn satisfied the OP's tone quest.
I certainly would not intentionally talk someone out of a more costly option. I know amp builders passion to create something excellent will certainly pay more dividends then actual sales. It's like trying to survive being a musician. Gotta do it cuz you love it.
