Re amp, I am sure if you only have a few gigs, Jack or i could lend you something appropriate (eg, he has my old Phil Jones Briefcase combo) rather than you spend moolah. However if you wanted to do so, you just need something relatively uncoloured and un-gnarly. There's some very cheap gear on BC that would fit the bill (eg, Deaver has a GK 200MB combo for just over £200 with gigbag, which used to be mainstay of travelling DB players)
