Nice setup, and that's a sweet guitar!
I used to have a Roland JC-120 amp like that. I wish I still had it.
I picked up the Roland a week after getting the Ibanez. I had been running my tele through a Line 6 2-10 amp, and it just was not a good amp for the Ibanez (which incidentally had been souped up with the addition of Seymour Duncans)
This particular Roland is a newer generation amp, and it just isn't as quiet as the old ones were - or at least I think so. Is it normal to hear a hiss when no signal is going through the amp? I mean, it is powered up of course, and the gtr is plugged in, but even with the volume on the gtr dialed down, I hear hiss. It isn't that bad, but I guess I expected total silence.
One other thing, the amp is a bitch to cart around; I am grateful for the casters.
I just got a new 30-watt Vox Valvetronix (has a tube in the preamp), and also was surprised to hear significant hiss coming from it when the master volume is up a bit, even when there's nothing plugged into it. Jeff Blake told me that his tube amp also has hiss, so I just assumed that it's because of the tube.
