True - I was getting a fizzy sound out of my amp's line out years ago and this is similar. The clean channel was always ok for line out from what I remember but it was always much lower volume for both.
It was okay when I mic'd the speakers but was at a much lower master out and pre was just a little higher. I'll try the mic later and see if it persists - it could be time to pick up another amp but I can always use Mike's JVM210 for now and get one of my own when $$ are available. I've had this amp for a long time...
I wonder of it's the master volume being so much louder leaking out more fizz....I've heard the fizz comment a lot over the years (not just the line out either) and never had the problem myself. Again - it may be the louder master causing the amp to show it's true colors (or fizz). I usually only go about 10 o'clock on the masters when playing through the cabinet.
It's not your amp. It's the line out. They're never good by themselves. The line out is really designed for live use or with an external poweramp. Rack poweramps were all the rage back when your amp was made. Or the line out would go straight to the soundbboard, through the amps, and out through the monitors and FOH mains. So in essence it is still going through a poweramp and speakers, just not your cab speakers. It's probably never going to not be fizzy for recording unless you drop a good cab sim on it. And even then it might still be fizzy because it's all preamp and never hitting the power section.
I'd say keep that thing for quiet jamming or whatever, but mic your cab for recording.
Okay - I tried to lower the amp back to my normal micing levels and still got some fizz on my LPC - but less. Then I tried my Strat and there was no fizz (or not audible to me). I recorded the LPC and Strat (clean and dirty) then my laptop died because of overheating - and I forgot to save lol.
I had the laptop on my amp head on top of a folded sheet to even out the handle thingy and the laptop vents were blocked. duh
So can you clarify your post - the speaker out goes to the CabClone then the line out of that goes to my interface - the master makes it louder so it must be going through the power amp section right? So the fizz is within the amp - unless you mean the line out of the CabClone is crap?
I've been recording at Mike's lately because of my daughter's studying - that's why he got me the CabClone. I've tried my LPC only a couple of times through my amp but haven't recorded anything yet (except tonight). It doesn't have the fizz from what I recall playing through the cab but now I'm second guessing myself.
I want to try a bunch of things maybe tomorrow (too tired now) and then listen to what I get:
LPC + CabClone + 1/4 line out
LPC + CabClone + XLR out
Strat + CabClone + 1/4 line out
Strat + CabClone + XLR out
LPC + SM57 off speaker
Strat + SM57 off speaker
Yeah the XLR out is definitely better than the previous line out clips. Still a hint of fizz but that can probably be dialed out with EQ at the amp.
But the mic'd clips are better. They have a "rounder" fuller kind of sound.
