I do actually know people who can scout Denmark street for me, in fact I think I will email one of my mates with whom I used to work at Soho Sound House (on Charing cross, one block from Denmark street) he still works there, so I'm sure he can help me out.

Playa, I generally stand about 5-6' from my amp, I'll try a little further...perhaps plug my amp and effect in at different sockets at the wall...I'll give it a go.
