Tube types, transformers, bias (naturally), and a whole host of other small details that make up the big picture sound of your amp. Inside the app, you can choose from a wide variety of amplifier types, and from there you can edit many of the different parts that make up an amplifier’s core sound.
Using either the USB connection to your computer or the Bluetooth antenna, you can connect to the BIAS Amp standalone app on desktop or mobile and go inside the amp’s advanced features. But venture to the connectivity of the amp, and there’s a multiverse of editing features available to you that will take you far beyond the typical control panel features. And if you never ventured beyond what you can dial in on the front panel, you’re still in pretty good shape – there’s a small galaxy of tone shaping options there alone. Some knobs and switches, an input jack, some LED lights. Both include a 600w solid-state power amp, which eliminates an entire separate rackmount unit from your rig – that’s handy! The rack unit is quite light, easily carried in one hand, and won’t add much to your rack setup’s weight.Īt first glance, the Rack looks much like the faceplate of any typical amplifier head. So I was excited when the BIAS Rack was introduced, a 2U rackmount version of the BIAS head, with all the same trimmings. I tend to think that lunchboxes like it and the Kemper are a tad awkward looking, and seem somehow fragile compared to a typical headshell amplifier sitting on top of a cab (although they weight significantly less). PG’s first foray into hardware was the lunchbox version of this amp, simply called the BIAS Amp. That was the case for me before they sent me one to review – I’d used their BIAS desktop plugin and BIAS FX plugin pretty extensively, but I’d never plugged into one of their physical products before. But it might be that you’ve never plugged into one of their hardware BIAS amp modelers such as the BIAS rack. Or perhaps you’ve played one of their recent multi-pedals that have been released. Positive Grid is a company whose BIAS mobile apps you may have used to dial up a tasty amp sim sound, right on your phone or tablet, or maybe on their desktop version.
