With BH550 we're building on everything that people loved about the original BH250, by simply throwing in more of what made the amp so innovative. You get more power, more punch and more creative features without compromising with the original's ultra-lightweight design. On top of that you get a highly intelligent EQ section, and a build in tuner. And you know what that means... total tonal bliss!

TonePrint - Instant Inspiration

TonePrint: Complete Creative Control

No longer is your creativity held back by some fixed set of build-in effects! With the innovative TonePrint technology you become the amp designer. So if you need a swirling vintage flanger and a TubeDrive for your next rock gig, or a compressor and a chorus when you play with your funk band, you simply just load them into the amp. This may sound surreal, but trust us, it's THAT easy!

TonePrint means signature effects made by the most awesome bass players around, like Victor Wooten, Duff McKagan, Nathan East and many more. These TonePrints are available for free, straight from your smartphone - and with 2 switchable TonePrint slots available, you can mix and match to your heart's desire!
Art. Where Technology And Design Meet.

Long gone are the days where bassists where the quiet dudes side of stage staring at their shoes pumping roots and fifths. Today's bassist is versatile, expressive, loud, and ready for his place in the spotlight. To perfectly support the needs of our fellow lovers of low-end, we've designed the BH550 to fit the needs of busy bassists on-the-go. That means a lightweight, portable design, a killer EQ section and unlimited tonal versatility through TonePrint - plus an on-board tuner. So just like you, this amp was born to rock!
Tone Is Where The Heart Is

We don't know what magical schools of Bass-Wizardry our engineers attended, but boy do they know tone! And with the BH550's intelligent EQ section we've once again placed ourselves far ahead of the tone-tailoring-game. Behind the deceptively simple four dial design lies a frequency range perfectly tuned for bass. So no matter if you like your sound nice and scooped, fat and groovy or filled with high-end sparkle the BH550's tone controls will be sure to cut and boost in all the right places, leaving you sounding your best every single time!
