This is the non-powered (aka preamp) version of the Positive Grid Bias Rack, perfect for the studio or putting through a PA. My unit is in mint/like new condition. The price is firm!
GOT PEDALS?
BIAS Rack is the most flexible pedal platform in the business. No matter how you currently connect to your pedalboard, you can swap the BIAS Rack guitar amplifier for your old amp in less than a minute.
Not only that, BIAS Rack’s sonic flexibility means that your pedalboard can be more flexible too. Gone are the days of building a board with pedals that only work with the one guitar amp you’re currently gigging with - now you can put together a much wider tonal palette.
SONIC FLEXIBILITY
BIAS Rack is a rackmount processor that was made for the stage - it sounds and feels like your favorite classic and boutique tube amps, but offers entirely new sonic flexibility. The advanced component emulation engine captures the warmth, girth and feel of real tube amps, authentically recreating the complex circuit behaviors that make them do what they do. From djent to jazz and everything in between, our BIAS Rack is deeply rooted in the rich history of tube processor design while remaining aimed directly at the future.
INTUITIVE OPERATION
Harnessing the power of BIAS Rack 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 rackmount amp’s front panel knobs, so it’s completely intuitive - no laptop or mobile device required.
POWERFUL SOFTWARE
If you want to dive headlong into the world of amp customization, BIAS Rack comes with our amazing BIAS AMP Pro software suite (a $199 value), allowing 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 design 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
CONNECT YOUR RACK AMP TO THE CLOUD
The BIAS Rack rackmount amplifier and all BIAS products can connect to the Positive Grid ToneCloud®, a cloud-based community specifically for modern musicians. It’s much more than an online storage tank for sounds - it’s a place to discover new ideas and new tones. You can download new amps created by artists and recording studios, backup and share your own creations with other guitarists in the community, and interact with other musicians with similar interests.
BIAS AMP software features the ability to Amp Match®, analyzing a source amp tone and applying the necessary corrective processing to make a custom amp match the original. Even if you don’t plan on matching amps yourself, you can still take advantage of the technology by downloading custom amps from other guitarists and studios. Instead of having to choose from a small collection of “factory amps”, you have access to thousands of different custom amplifiers on the ToneCloud® !
A RACKMOUNT PROCESSOR FOR EVERY GIG
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 actually need multiple amps to cover all of the sizes of gigs they play, and that just gets flat out expensive.
