One Control Blue 360 AIAB Amp-in-a-Box!
Overdrive Effects Pedal for Bass Guitar
Inspired by the vintage Acoustic 360 Preamp
While guitarists have often expressed disdain for solid state amplifiers, bassists have traditionally been more open-minded. While there have been quite a few respected solid state bass amps over the years, none are as legendary and storied as the original Acoustic 360 preamp. In fact, the Acoustic 360 may be one of the most-heard but least-acknowledged amps in music history. John Paul Jones used a pair of them with Led Zeppelin, John McVie used them in the early days of Fleetwood Mac, and the 360 was the favored amp of legendary bassist Jaco Pastorius.
The newest member of One Control’s rapidly growing collection of Amp-in-a-Box (AIAB) style pedals, the Blue 360 AIAB reproduces the sound of the legendary 360 preamp, and can be used to give modern, high tech bass amps the response and tonal characteristics of 70’s-era high-powered transistor amps. Blue 360 delivers a bass tone that fits in perfects with high-density, powerful band sounds – especially those with high volume, distorted guitar – making it a great option for classic rock, punk, etc.
A switch on the side of the pedal marked 0dB / -18dB, works as a pre-set master volume. All boost is set by the Volume control. At the -18 dB setting, cranking Volume to full will deliver a similar level to bypass mode, allowing you to set the pedal to create distortion tones when on, while keeping your signal at the same volume whether the pedal is on or off. At the 0dB setting, the output level will increase as you turn up the Volume until you reach 360mV of clean sound or 600mV of distorted tone. Typical instrument level is just 60mV, so 600mV is enough to drive a standard power amp. If you do use the Blue 360 as preamp into a power amp, the sound will start to distort on transients at the full power of the power amp. Just below 600mV, you’ll get an almost-clean, compressed sound that amplifies weaker notes but veers into distortion at peak transients. This response is very similar to how transistor powered bass amplifiers were made to compete with roaring tube guitar amplifiers.
