Cheers for the posts guys :)
I own the Marshall Compressor and have owned the Guvnor 2 in the past, so I know I can rely on Marshall pedals.
That Carl Martin Surf Trem looks really interesting! And it's only £50 which is actually cheaper than a new BOSS TR2 Tremolo!
If I can find some sound clips of it, I may have a contender to a used BOSS Tremolos throne :D
