I've got a VHT module in the classifieds...Made by Jaded Faith and really close to the Deliverance amp...Very strong high gain that is very articulate...It may be just what you are looking for...Seriously, not just 'cause I'm selling it...It would be among my recommendations of ones to try....I'm selling it for just 220 shipped and it's built of a KH-3 to begin with - and that alone costs more than what I'm asking...Not to mention the modding...
Great deal that could be the answer to your quest...Or at least an important piece of the puzzle....
Either way, good luck! The JF Ultra XL is nice too...Saw you mentioned that one...I've had that one in my rack too and it is a good one...
