And is it new or did you get it second hand?
Yep, you can do that It is a speaker sim, but it has a blend of sim vs raw signal from the head, too. You can dial the sim completely out, though, giving you totally raw head (pre and power amp) signal, for you to load impulses onto.
Here's a clip I made with my 5150 + Palmer + impulses - http://dl.dropbox.com/u/4128689/5150 Test 2.mp3
Absolutely man, that was the first price I posted, and forgot to lower it like I had elsewhere. I'd be willing to do it for £200, + postage (probably about another £15-20 for Ireland). So more like £220 all in all (250~). How's that?
I know how it is dude, I bought a 5150, an OD-808, and this Palmer last month, much to her dismay
I just don't need it man! Well, it's half that I don't need it, and half that I need other gear/bills paid more. I'd love to be able to afford to hold onto gear that I'm not going to use an awful lot, but right now I need to strip back to the bare essentials unfortunately
