This preamp provides a great interface for almost any mic. I particularly like it in a vocal chain with a U87 or TLM49. Works as a DI, but for some reason I get a hum when passing through to an amp. Some are worse than others. Noisy guitar amps are often even noisier using the 610 in line. Removing the earth from the mains leads sometimes helps and the ground lift switch makes no difference. Small trade off for an otherwise fantastic sounding unit. The built quality is also superb.
The solo 610 is a Great Pre, certainly adds a nice bottom tube sound to almost anything i run through it. A great must for decent sounding vocals. Has a extremely low noise ratio which please's me. :) email@example.com facebook: Donovan da don Leon Twitter: @dclstudioz
