I find that it is best to try out the gear before buyiing. So does anyone know where i can try out the um mage I'm living in London. Or will can anyone let me adition their own mage for a few minutes?

I'm using um2 for more than 3 years, it's been great, i like the over all sound of that. lately i'm thinking of going custom. bugdet 400$, 70% of the time i listen to prog metal ( dream theater, lte, opeth, circus maximus...), so there'll be a lot going on at the same time. so i want good speed...

I can't decide between er4p and SF.5 pro's I listen mostly to Dream theater. So i need good mid-range for the guitar. It must be clear to hear the instruments., but still solid. Normally i would pick er4p but i'm worried about the sound being to sharp or thin. And is the SF.5 pro's bass too...
