Capturing the inimitable tone of a gear legend and making it accessible to the modern musician, the Roland TB-03 Bass Line Synthesizer is an attractive piece of equipment for any synth enthusiast. Borrowing the Analog Circuit Behavior (ACB) technology that put the AIRA series on the map, the TB-03 serves up that same tribal, undulating bass sound as the original but in a chassis that you can fit in your bag. Speaking of the chassis, you'll find that this update retains the feel and workflow of the original with updates like a four-digit LED display, coveted TV sequencing with write and playback modes, and USB/MIDI connectivity for making sure this low-end monster plays nice with your other gear.

    Sounds as close as possible to the TB-303, but it's just not analog... It's great for recording and doesn't need as much processing as the original TB-303... "GREAT SYNTH".

    I've had a x0xb0x for a while and have been lucky enough to play with a real tb-303 a couple times. and this lil guy is a true acid machine. It squawks, squelches, and squeaks like the real deal tb-303, but it's not gonna cost you an arm and a leg. You wanna make some acid basslines, but don't wanna break the bank? Get it!

    Loved how simple, quick, and effective the purchase was :) It sounds great (which is saying a lot because this was a gift and I don't use it directly, but it's being used and loved daily by its owner)!
