"excellent sound!"

i use the mini-pre together with an audio technica 4033a mic and a roland vs 890 harddisc-recorder.
before i bought the mini-pre voices and guitars sounded cold and digital. the mini-pre adds a brilliant warmth for a really cheap price.
before i bought it i compared it with the art tube mp and other low-cost pre-amps.

"Turn your digital studio into a real studio"

Let's face it, didgital studios are great, the keyboards sound great, the guitar modelling is uniformay excellent, and the vocals sound like you did it on an answering machine. If you have a limited budget, but want to get as close as you can to a full finished sound this is a must buy item. It transforms dull flat vocals into warm, rich, full natural, and musical tones.

dbx Professional Products has been redefining the standard of Professional Signal Processing for 30 years. From the 386 Tube Microphone Preamp to the 586 Dual Channel Tube Microphone Preamp, dbx has been the Professional's choice when it comes to the classic sound of tube microphone preamps.

The Mini-Pre takes the classic dbx Tube Microphone Preamp sound and puts it in an easy to use, compact, affordable package. With the new dbx Mini-Pre Vacuum Tube Microphone Preamp you will no longer need to compromise tone for affordability.

Classic dbx Tube Microphone Preamp tone, portability, and affordability are the hallmarks of this new microphone preamp from dbx.
