Decent Mic Pre at affordable price

By Anonymous

from Undisclosed

I have what is basically the same unit, but it use be called the "Ghost" TB101. It has compression, three eq points, and phase reversal, which is probably the nicest "feature" for a product in this price range. All in all, it sounds good.

cheap noisy box

By fretless

from Little River, SC

While the features are effective, the overall noise floor of this unit is ridiculously high which renders this unit fairly useless even in live sound situations where noise may not be as critical. skip this unit and use the preamp in your board.
