I have two MXL ribbon mics up for grabs. They are great for mic'ing guitar cabs. MXL says the R144 will transduce without distortion up to 130dB SPL.
One mic had a floppy ribbon when I got them used some years ago , but still it works - listen to the attached MP3 test recording. The recording was made with the mic about 3 inches from the amp's speaker cone, with the amp at bedroom volume. The R144 went directly into a Scarlett, input gain at 2 o'clock.
You can use Mr. Floppy as is or else practice re-ribboning on an inexpensive mic body. R144s go for about $100 new. I'm asking $135 including shipping in the Continental US for both. Each comes in a hard plastic case with a suspension mount, unused microfiber cloth, and MXL liturature.
