DI Box

high performance signal buffer intended to be placed at the start of effective channel for supplying more pedals minimizing the induced noise which often afflicts high impedance circuits. It includes load correction circuit Dragster owner and the same buffer in class A as the Radial JD7. A fully discrete amplifier gain and class A is also included.

The ultra-compact design exudes a high-impedance instrument input. The signal is managed by load correction technology 'Dragster' Radial gives the impression of being connected directly to the amp. The signal is then 'buffered' by a circuit 100% discrete class A unity gain. This type of circuit from Radial JD7 is used by guitarists also diversque Steve Vai, John Petrucci, Steve Lukather and many others. Once buffered, the SB-15 Tailbone lowers the impedance and the risk of buzz caused by radio interference or electromagnetic fields. The SB-15 is then capable of powering multiple remote pedal 15 meters without any noise.
