Got a question about this product? Ask us!

The SonicTone BA-100 and BA-103 are 100-watt all-tube bass amplifiers. They're 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-100 and the BA-103 - 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. With such a great feature set, this bass amp will deliver amazingly warm and responsive bass tones that will cover a wide range of music styles.

BA-100

The BA-100 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-103

The BA-103 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.
