It makes playing the piano a lot more comfortable.

Cleaner and slightly warmer than the $300 peramps. I can tell a difference with this and my ART MPA Gold Preamp. Once again, save your money and buy a preamp in this price range instead of the $300-$500 preamps, "you only cry once when you buy the best".I have used this on lost of different insturments, sounds great on Vocals. Best yet is on electric guitars, SOOO smooth, and DI'ing my bass, WOW on the bass. Very clean on drumset, adds a nice tight deeper sound to the kick drum. you dont get this with the lower end pre's.Everything you need in a preamp. Wish it had TRS Outputs.Solid as a rock.Get a 15% coupon code for this unit.

great pice of gear for recording!

i used it first on drums, on kick snare and overheads and it sounds very nice. is not so colored like other brands but it gives the weight i need to the instruments i record. i used on bass and sounds amazing too compared to my focus rite pro 40 preamps i can hear the difference. i recommended greatly!
