Hi,
With the track examples you've given, I can only really think of a bit of
wah and overdrive in there - do forgive me if my brain is missing a bit!
But if
you're happy with the tone of your amp, I have to agree with the previous poster and say
'stompbox modeller' or even go back to good old fashioned stomp boxes.
I rarely
play live, but the floor box I've got is a Carl Martin Quatro
http://www.carlmartin.com/product%20quattro.htm. Dead simple - it
does delay, trem (later versions replaced trem with chorus), a compressor / clean boost
and 2 flavours of overdrive. No programming involved as it's a completely analogue beast.
An eBay Vox Wah and a home made fuzz pedal and I'm about done. But that's me and I quite
realise your needs will differ.
Bad news is they are around £400 new for very
few effects. I was an eBay £160 winner and love it, but (having just got a nice little
valve amp) I was keen to keep everything analogue prior to squirting it into the amp.
Call me old fashioned. And you'd be right.
Reason I mention it is purely to
ask you to think 'what effects do I REALLY use live?'..... If you really do use
everything, all power to your elbow

I've been
through all the line 6's and, for me, the only time I used the different phasers and
flangers and multi-ping pong delays was when I first opened the box and thought how cool
it was. And then failed to do anything with them

Of course,
YMMV on this but I think most of the boxes out there only have about 10% of their
abilities used and that's why a lot of folks prefer stomp boxes - you are then paying for
a top quality thing that you'll use as opposed to 98 things in a box of which you'll use
5.
All IMO of course
