Great Value Ribbon
Took a punt on a pair of R1 ribbons mics a while back when my Royer went the way of the Dodo. They were obviously far cheaper but I have achieved great results on a variety of sources. They worked great as a room pair when recording drums. I've used them on vocals and they give me something very different. I've utilised them as a pair of room mics for acoustic guitar as well and they gave me exactly what I was looking for.
sure you could probably get a more 'authentic' sound from a more expensive alternative, but for sheer value for money I'd recommend the R1. I'd buy a pair!
