Both the SonicTone BA-300 and BA-303 represent what has long been considered the "gold standard" bass tone - a 300-watt tower of all-tube tone. When you commit to such a amplifier, you open the doors to a bass sound like none other. It will be able to fill arenas all while delivering a warm, full bodied bass tone. It's loaded with features that let you dial in great bass tone, all packed into a 24" wide head cabinet. Available in two different models - the BA-300 and the BA-303 - they both share the same power section and basic features, however, their preamps are different, each delivering a unique sound. The amp also has an FX loop, preamp out/power amp in jacks and a transformer-driven balanced XLR out. Simply put, this bass amp will deliver amazingly warm and responsive bass tones that will cover a wide range of music styles - and it will do so with great authority.

BA-300

The BA-300 is a modern rock bass machine with a thick low end. It's a 2-channel bass amp with independent clean and drive channels. The clean channel has a wide range of tone and the drive channel will let you dial in some high-gain dirty tones - perfect for rock and metal.

BA-303

The BA-303 is a throwback to vintage bass tones of the 60s and 70s with a preamp that delivers a thunderous and punchy clean tone with lots of headroom. It has 2 parallel channels that can be used separately, or blended together to dial in the perfect mix between the two. Channel 1 is voiced darker and channel 2 is voiced brighter.

Available as a head.
