Source Audio ZIO Analog Bass Preamp + DI

General

Sculpt your bass sound in great detail with the Source Audio ZIO Analog Bass Preamp/DI and enjoy naturally overdriven sound packed out with ample punch and grit. This quality pedal works exceptionally well in combination with an amplifier but can just as easily serve as a standalone preamp/DI. Shaped with the help of high-quality Burr-Brown op-amps, the rich, dynamic output is backed up by more than enough headroom and is perfect for warm-and-punchy, vintage-style sound.

Clean Up Muddy Frequencies With The Focus Control

The fitted Bass and Focus controls help deepen your sound without muddying the lows. The Focus knob essentially functions like a high-pass filter for eliminating unwanted frequencies, while the Treble control does the opposite and boosts the high frequencies. Simply find the sweetspot and you're left with a supple attack and perfectly balanced sound.

Natural Drive Thanks to Grit and Scoop Switches

Source Audio has mounted a Grit switch so you can instantly turn on the magical effect of the 'breakup' that happens when a vintage amplifier is pushed to the edge to produce a natural overdrive. This not only gives your sound a dirty edge, but results in a fierier response. The ZIO also sets you up with a Scoop switch, which simulates the EQ curve of the 'Pultec trick' that studio engineers would pull off back in the '50s to boost the mid-range frequencies without muddying the sound. Here, it basically functions like a natural-sounding high-pass filter that you can flip on as needed.
