With its heavy-duty linear power supply, the BF-S has a noise floor of better than 70 dB – almost unheard of for tube gear.  With this power supply, the BF-S is flat from 15Hz to 80 KHz (-2db)!  The BF-S weighs a good bit more than the BF-1, and we’ve encased the unit in a powder coated steel enclosure to withstand the rigors of daily use on a tracking room floor.

Most tube DIs start with the design philosophy of a guitar amp.  Not the BF-1 or BF-S. We assume that if you want a guitar or bass amp, you’ll buy one.  So we designed these two units to compliment  the amp, while at the same time offering a different method of impedance conversion that delivers clarity and depth for recording.

DI recording is usually a bit of a bummer.  Even with a really good DI, electric instruments sound lifeless at best, or tinny at worst.  We mean to change that.  The BF-1 and BF-S sound exuberant – adding just a touch of second harmonic to make the subjective listening experience compelling without sounding like the instrument has been altered in any way.  Instruments just sound alive.
