Thanks for the info lads, and especially those videos, that's what I'm talking about - and JCM is the best system in my opinion.
And a massive thumbs-up to Nerd for coming up with it!

Anyway, I'll have to cut this short, I have to log-off, I just caught one of the people who work here posting messages on the forum using my pumeco account!  I'm logging off and I doubt I'll be back unless I'm satified with the answer for it.  I knew there was something going on here.
