I agree.
Yikes... Then we'd have to research whether or not there even IS away to get rid of it. That stinks.From my research, the hiss is definitely inherent in the amps
I even plugged in to an APC power conditioner and voltage regulator and the hiss remained
I did come across this:Yikes... Then we'd have to research whether or not there even IS away to get rid of it. That stinks.
A quick glance at the thread shows that is not a good mod/answer. And, while the one guy knows his stuff, that JRC chip is not that noisy (it's used in MANY pedals) so it must be the circuit in general that is the issue. A low noise, hi fidelity IC (burr brown) might help, but the JRC shouldn't have enough chip noise to be THE issue, which tells me it's the overall design... and that's a bummer.I did come across this:
Hey Roland JC owners...wanna kill that dreaded Hiss?
Always annoyed me - that horrible hiss on those Roland JC amps...well this gent found the culprit...I did it to my JC77 and a thousand times better! A simple resistor replacement (R46 from 100k to 2.2k on the JC77...find that opamp stage on your JCXX and and do the same...) All nice and...www.diyaudio.com

I might read further later (I'm doing all this while on hold) and see if someone actually resolved in in an acceptible manner. 18db reduction of gain to get rid of noise is NOT an answer!
uh... does this have a speaker load?I just removed the speaker connections (taped over the ends with painter's tape (even though they were covered with a silicone wrap), plugged the direct out into my audio interface, dropped in the TwoNotes JC-120 speaker DynIR on the track and it is glorious -- both the JC's reverb and chorus still work and there is absolutely no hiss or noise from the direct out from the JC
Clean clean clean for days!!!

Don't have time not to research, but YOU should. I'd ask the manufacturer if this is safe. Just because it's SS doesn't mean it is safe to run with no load. Some SS circuit types are not, and this includes some newer Class D stuff.There is a direct out from the amp to my audio interface - not going through a load box
The amp is solid state
I didn't know PRS owns Roland.
I've been here a long time, and know that for a long time in the past PRS' folks didn't appreciate references to other brands. Shawn used to delete them, because it says, "Discuss PRS amps," or "Discuss PRS Guitars" on the forum headers.I didn't know you were the PRS police
I see you have posted a similar comment in my other thread about a Gretsch guitar yet, you comment and engage in the conversation in other threads about non-PRS made gear --- did I offend you personally in some way as to cause you to single out my threads?
It actually says, "Amplifiers" and underneath that says "Discuss PRS Amplifiers, CAD Amplifiers and PRS SE Amplifiers."The heading of the discussion area is designated "Amplifiers".

I'm not seeing much room for interpretation there.
We're PRS' guests here; seems to me that we should respect our hosts' wishes. NGDs and NADs relating to other manufacturers don't seem respectful, at least to me. Doesn't appear to me that Strat Talk Forum is owned by Fender, so that's more like the old Birds and Moons forum that was independent.
There's a lot that makes this place different from a TGP. Some of that comes down to a mutual understanding of what is, and isn't supposed to happen here. You get a PRS, great, interesting, belongs here. Seems to me there are other, more appropriate places to post the pics and the brag for other brands.
It's not a big deal, and I don't see why anyone should be pissed off about someone being reminded of it.
