Fender 75 from the early 80's -check out Mato Nanji (Indigenous) on youtube, etc.- FANTASTIC! (I know it's from Fender, but seemed obscure to me - never heard of it til I researched Nanji after seeing him in a club and was blown away). I bought one off Craig's List - very strong amp head.
Holland Amps, made in the 90s by Mike Holland. He got some rep for a great Bassman version called the Gibb Droll, after a NC guitar player. He disappeared from the amp world though and you don't hear much about him and he didn't make many even when he was working on them full time. Great amps, most of them unique in some way. I have Champ variant in a large 1x10 cab, about 6 watts, switchable from single 6V6 to single EL84. Sounds incredible. It was the first great, simple amp I ever played through and it lit my ears up from the first note. 'Ah, yes, I get it now!"
I just flipped a KMD amp. It's pretty awesome for GNR style stuff. My guitar was out of tune, and its a bit blankety because it was recorded with a camera (not a video recorder/proper mic etc). And has "jcm" cleans. lol. But it is great for gnr style stuff. I did this clip last night to flip it. I sold it today for $260 Clip is non boosted etc.
How about Kingsley amps? I know Simon Jarrett's pedals have raised visibility on his incredible products, but it seems that only few have actually played his amps since they have no U.S. distributors. If you love Simon's pedals, you will love his amps even more. Kingsley amps are amazing, inspiring tone machines.
I'll repeat Phaez. Seems like he's starting to get some credit, so they may not be as obscure as they were not long ago. Definitely killer. Easily among the best I ve played.
Red Iron T-Rex is still obscure. It is my all time favorite, mid power NMV amp. Miss the one I had...
that traynor is insane very well done great playing I always thought Meanstreets was F# I also thought Iron Man was C so much to learn
