POSITIVE GRID Bias guitar amp head
Harnessing the power of BIAS Head is easy - just select one of the 25 onboard presets, grab a knob and start tweaking. Need more grit on your clean tone? Add another tube stage to the preamp. Want the power amp to feel more aggressive? Change the circuit topology and push the virtual power tubes harder. Prefer a crisper treble response? Flip the power amp presence switch to Modern and hear the top end open up. All of this tweaking is possible directly from the front panel knobs, so it’s completely intuitive - no laptop or mobile device required.
If you want to dive headlong into the world of amp customization, BIAS Head comes with Positive Grid's amazing BIAS Amp Pro software suite ($199 value), which allows you to recreate the sound and feel of nearly any existing amplifier. Even better, it gives you the power to create an entirely new amp that is unique to you and the way YOU play.
Connect via built-in Bluetooth or USB, and open up a world of component options previously only available with a soldering iron: choose between different preamp and power amp circuits, change the tubes and transformers, add clipping diodes and try out different rectifiers - all completely authentic and all in real time. It’s like having a boutique amplifier workshop at your fingertips.
Deciding which amp to take to a gig can be problematic - tube amps can be heavy, and they’re designed to operate within a specific volume range. Many guitarists find that they need multiple amps to cover all of the sizes of gigs they play, which is expensive.
That isn’t a problem with BIAS Head, because it sounds and feels authentic no matter where the master volume is set. The built-in 600-watt power amp can handle any gig you throw at it, and at less than 12 pounds you won’t have to take separate trips when loading your gear onstage. Add to that super fast patch-switching and a glitchless effects loop, and you have the ultimate gigging amp for every situation.
