SB-4 PIEZO

Radial Engineering's StageBug™ SB-4 is an active 48 volt phantom power DI box optimized for use with piezoelectric transducers, such as those found in acoustic guitar pickups or stringed instrument pickups. Most typical direct boxes with a 1/4" input have a 1 meg-Ohm input impedance, but the StageBug SB-4's input features an impedance of 5 meg-Ohms to smooth out troublesome peaks and high-frequency content that can sometimes cause issues when using a piezo transducer. The StageBug SB-4 also comes equipped with a high-pass filter and a 180° polarity reverse to help eliminate feedback while on stage. Phantom power is derived from the console's 48 volt phantom, eliminating the need for batteries or an external power supply while using the SB-4.

Features:

  • Active DI optimized for piezo transducers
  • Smooths out peaks, eliminates squawk
  • High-pass filter eliminates resonance
  • Ultra-compact to fit in your guitar case
