already knew the dwarvenauts where modded jet city amps but thanks for putting that out there, i bought one of these amps and i have to admit the dwarvenaut i bought does do matamp/orange/sunn model t tone gotta tweak the eq and depth knob but it will do dead on tone stacks of each amp listed i really like how i can turn it up and get a fuzzed out bigger than balls stoner/doom rig tone, or you can back the gain off and get some cleaner esc tones, i opened the head up to have a look at the mods they look fairly simple didnt really see any tweaks the the pcb board more or less add ons to the tone stack and of course the double depth mod has alot to do with it....................now for the bad news for what i paid for the amp my heart sunk when looking at the faceplate and back of amp chassis as all jet city was scratched off and went over with what appears to be sharpie marker as well as front of chassis in my personal opinion i would have liked to have seen paint used to cover up what was scratched off ...... other than that i was surprised to see the cheaper than dirt stock Chinese tubes still in amp would have been happier with upgraded tubes(tung-sol,jj,mullard,ect) i have yet to see or hear a Andromeda in person so i cannot comment on that head, hope this helps anyone looking at these amp heads keep in mind i dont regret buying the amp but for the money paid feel a little shafted.
