That's good to hear !
Any chance of of a few more details on the JSX ?
Carvins (with the exception of the Legacy)are pretty non-existant in the UK so that's not really an option.
On my budget it's gonna' be a Peavey or an Engl for sure.
It's also gotta' be an amp that will work well with 6 + 7 string guitars as i play both quite a bit(another thing that's drawing me towards Peavey or Engl).
I hadn't really been bothering with 6's for some time but i got my hands on a Parker Fly Deluxe recently (i've wanted one of these for a looooong time)and it's absolutely amazing in every way so i'm having trouble putting it down.
EDIT; J.Arledge has thrown a spanner in the works while i was typing this post(oh nooooo!!!!!
I suppose it depends what gear your using it with to some extent too.
I've heard a lot of people say that the Crunch channel on the XXX and the JSX are VERY similar.
That's why i'm still tempted to go for the 5150/6505 or the Fireball.
Guaranteed BRUTAL Metal tone from both amps,and i really like the way both amps sound too.
I was thinking of running a new amp just for my ideal full-on Metal tone and use an AB-Y splitter pedal with one of my current amps set up for a nice clean channel
