MJE Hulk 990 (modified MXL 990)
New MJE Hulk 990 (modified MXL 990)
Michael Joly Engineering transforms the lowly MXL 990 into the Hulk 990  - only $399 complete with shock mount and case. 
Many folks need one great mic to record vocals, acoustic guitar and percussion. The MJE Hulk 990 is that mic. The 3 micron diaphragm MJE-K47 capsule offers classic “Neumann-esque” sound up to 10kHz then keeps on going to deliver a touch of sparkle in the “air” band. Record an acoustic guitar track, then reposition for male or female vocals. Classic LDC sound and vibe on both takes. Move it into position as part of a Glyn Johns-style three mic set up for drum overdubs – hear punch, clarity and shimmer with no top end harshness. Hear it vs. the current industry-standard Neumann U 87ai. This is our most popular mic - just write and find out why!
