MXL R144 by nugznmugz
If you're like me and you wanted to try a ribbon out, but didn't want to save up for a year to get a R121 or something like that, this is a great mic to start with.
Just like most ribbons, it's a bi-directional mic. It does have a lot of low mid coloration, and it doesn't have an extended top end. In other words, dark and warm. You can swap out the transformer in it very easily, and it does sound more open with a better transformer, but the mic costs as much brand new as the transformer does!
The figure of eight pattern is really cool when you need good rejection from the sides. A trick you can use is to put one of these in front of a guitar cab with something kind of reflective behind it. Moving the reflective surface closer or farther away will add more or less reflections while maintaining the isolation and clarity that you want. I like to use them in conjunction with a LDC to have some high end.
It comes with a solid case, shock mount, replacement bands for said shock mount, and a cleaning cloth (?). Not a bad deal for around $100.
If you want to get a inexpensive ribbon, even if you don't have any particular use, get two of these! Guitars, overheads, horns, vocals, whatever you want to sound warm and dark. Just keep in mind that it does take a substantial amount of gain to get these puppies singing, so make sure you run it through a decent pre. It doesn't have to be a SSL console, but definitely something with a lot of gain and very little noise.
