GEM s bass 50

it is a tube amp, 4 el 84 and March 12 AX7 50w but lamps!
I bought it yesterday in a cash I know what. the guy told me, you want to try? of course I said yes. it takes me a guitar and the party branch and voila me, as gently as possible and it was already very strong. he said, you can go. good, never mind, I set the volume to half and a small rock rif., lol, after 3 minutes, he told me, I think we're all deaf! hey, this is to say that 50w tube is not transistors.
it is wired by hand, it's nice work.
I've put pictures of the inside of the cabinet and it has two hp 15p

UTILIZATION

I just got it and I did not even turn, there are two channels with two inputs on each channel and three entries for hp, weird?
for her I'll come back ...

SOUNDS

so I just tried speed, there is a buzz but the sound is excellent, the first channel has plenty of gain and is incredibly powerful type 3 person remains ahead. a lot of dynamics. knobs for bass and treble play their role. the other channel is indomitable, but more interesting question. I'll come back when I have better tested.

OVERALL OPINION

so I just bought it. it really is a great amp but I removed it and I need to change the larger capacitors as seen on top of that he died and as I do not want to toast the transformers, I'll wait to change before going further. more stand by was removed I do not know why. short there is a little work in there before I tell you more.
So soon for more.
