Enhance the clarity, detail, and dynamics of your instrument's sound with the BF-1 Tube Preamp/DI from Useful Arts Audio.
 
Whether used between the instrument and amp, the instrument and a PA or recording device, or all of these at the same time, this all-purpose interface is designed to get the best sound out of a guitar, bass, or any instrument with a pickup while avoiding unintentional alteration of the sound's characteristics. Boasting an input impedance of 20 million Ohms, the BF-1 captures even tiny details in the signal and pumps the results out to an amp or console in useable form. The BF-1 can simultaneously drive an amp through its 1/4" output jack and a pro audio device via XLR. Instead of stopping at massive impedance conversion, the BF-1 also offers a Class-A tube preamp, a two-band EQ, and dual outputs that can be used simultaneously for your amp and console. Bypass the EQ, and you have a choice of low gain (much like a traditional DI) or high gain, which gives you the ability to go straight to the converters for pure high-fidelity line-level recording with no other amplification needed. For bass players, the BF-1 can actually eliminate the need for an amp.
 
The Features
- Small and rugged enough to put in a gig bag and use every day
- Uses the input tube the same way as a tube microphone—to convert impedances without the high gain
- Preserves the sound of the instrument in a way that the input stage of an amplifier or a console can't
