Come on Guys....enough with the tubes/valves already! As far as I am concerned, BOTTLE amps belong to a far-gone era when milk was delivered in BOTTLES to your doorstep at five in the morning by your friendly milkman (and it was still there when you rose at seven)
I have a pre-owned Roland JC50 purchased in '87 and it is MY sound! Trouble is that it has a constant hiss even with no signal cable attached despite using external line filter and reversing polarity, etc.
It's not loud but is an annoyance and definately not studio friendly.
Any ideas how to eliminate or reduce hiss? I have recently cleaned up the circuit board, removed dust, etc and even removed the connector plugs which attach to the legs of the output trannies and soldered the wires directly, thus eliminating another potential source of interference.
thank you,
