  • Inside a Roland JC 120

    I am doing some basic maintenance this morning I thought some of you amp geeks would like to peek over my shoulder.

    What sort of maintenance do you need to do on a solid state amp?

      Pots would need cleaned/lubed for one thing.

          Exactly it doesn't get played as much as I would like. I use the Marshall for the band and for home practice it is usually the Classic 20 or the Excelsior. The pots were a bit scratchy when I got the amp now they right out need to be cleaned. It is the filthiest I have ever let an amp get.

              Ok, that makes sense.

                      The JC-120, with the proper pedal, is still one of the best metal amps ever made.

                        My Chandler Tube Driver is what I used in my thrash days. I was playing it with my DOD 250 when I noticed it needed to be cleaned. The DOD 250 plays great with SS amps.

                          When I was a kid, my buddy used a homemade RadioShack rat clone into one. This was like '82. He didn't Really like it, but it was brootal before anyone big was doing brootal.

                            The distortion on JC 120 from the 80's was nasty, but Adrian Belew worked it. The distortion on the new ones sounds great. Roland is rugged, dependable stuff. Wish I still had mine - had the best clean sounds.

                              Both Adrian and Robert Fripp made the most of that amp. But I think the trick was not trying to emulate traditional sounds.
