Woah - I've never even tried any of the vocal range on guitars (or anything other than vocals, for that matter). Should give them a go.. The 935 and 945 are incredible on vocals..
I only recently got a Sennheiser 903 - these are discontinued and Sennheiser in NZ had a few kicking around, one of which I grabbed to try out.. These things are AWESOME on guitar! I used one of those Shure drum mic clips and had the 903 clipped onto the 906's stand and had the capsules perfectly aligned - sounded awesome. In fact, I'll try get into the studio sometime in the near future to get some samples.
Someone on here (Mickrich I think?) posted a really nice clip of one of the cheapy Sennheiser vocal mic's (E815 maybe?) on a guitar cab recently and I really liked it.
Is that 903 the one that was made for snare btw? Always wanted to try either that or a 905 but they're not very common it seems!
That would be awesome man! What's the 905 like on snare compared to say a 57?
The i5 is on my list curious about that one!
Maybe someone could post a little clip with the i5?
Heard once a M88 Beyerdynamics on a Mesa Cab, and it truly slays. More detailed and realistic than the 57. I have to buy one. It's also terrific on a snare.
