I had a AE Throne Torcher, and for what it is worth, it was my favorite.I’m aware of the clones, but I’ve found I just want some chainsaw. Nothing extra, nothing “special”, just the HM-2 in all its goodness. Like you mentioned, they’re getting pricey, so I’m trying to find an affordable, well-built alternative/clone. The Swede seems to fit, but I can’t find many demos to hear how close it is to the real thing. The Behringer being plastic is a little worrisome, as it seems some enclosures and jacks will take a beating and others will not.
Clones I know of:
Throne Torcher
Hierophant
Arion Metal Master
DOD Super American Metal
KMA Wurm
Left Hand Wrath
Left Hand Path
Behringer HM300
Dunwich’s HM-2
Dungeon Master
Hangman 2D
FabTone (supposedly)
BYOC Swede
TC Eyemaster
Sure there are others I can’t think of...
I also had the Dunwich Order of the Left Hand Path (HM2). It was a nice, flexible clone, but didn't have THE sound.
I used them on bass, so YMMV.
