1.8u ribbon and Lundahl LL2913 transformers. Can take high SPLs with pop filter.
Eddie Kramer and Jimi Hendrix's favorite guitar cabinet mic. 'When the Levee Breaks' drum overhead mic. Bright for a ribbon mic but never harsh.
The Eagles used these live for vocals. Rush 'Permanent Waves' distant overhead drum mics. Very bright for a ribbon mic.
Dark sounding ribbon mic good for taming overly bright sound sources like guitar cabinets or drum overheads. Also works well for ambient miking. Sensitive to plosives and wind blasts. Often used in conjunction with a pop filter to alleviate stress on the ribbon.
Short 1.8u ribbon and Cinemag CM-9888 transformers.
I can’t believe how good these mics sound. These super cheapo Chinese ribbon mics were modified by Stephen Sank. He replaced the stock ribbons with RCA ribbon material. Transformer upgraded and JFET buffer amp added which is powered via +48v. These things sound killer. Great on voice and room mics for drums. Insane low end.
