Sonic Tools 

Experience a pure analog signal path that's based on classic VCA, VCF, and VCO synth predecessors. With a 16-step sequencer - equipped with 7 tracks featuring 250 user patterns - there's a seriously versatile sonic backbone to the unit. Experimenting with a suite of legendary sounds has never been so good!

Here's What Behringer say:

Sometime after the release of the original TB-303, creative users realized that there was more to squeeze out of an already amazing bass machine, to produce sounds that were unique to themselves. As word started spreading about third-party mods adding more functions and many more ways to shape sounds, synth-heads around the world wanted to get their hands on a modded TB-303. Now it’s a lot easier to get that awesome “modded-out” sound with the Behringer TD-3-MO-AM, an ultra-affordable and faithful homage to the iconic synthesizer that’s capable of creating some fiery basslines and much more.  

With its pure analog signal path, 16-step sequencer and authentic VCO, VCF and VCA filters, the TD-3-MO-AM is sure to become one of your favorite synthesizers. 

Pure Analog Signal Path

Great care has been taken in engineering the TD-3-MO-AM, including the true to the original VCO, VCF and VCA designs and pure analog circuitry with matched transistors. This highly-focused attention to detail is what gives TD-3-MO-AM its ultra-flexible sound shaping capability, which covers a wide spectrum for you to create some super-funky bass lines and pounding rhythms that can keep you, and the crowd, grooving all night long. 

Rock Right Out of The Box!

Your TD-3-MO-AM comes ready to rock, thanks to its default signal routing that doesn’t require lifting a single patch cable to instantly create amazing sounds. The highly-intuitive layout lets you easily tap into the inspired sounds of 1980s and ’90s wave, EDM and synth-pop music tracks that made history – or to design incredibly fat and original sounds that will make you a legend in your own right!

I would recommend the regular TD3 to be honest, I needed another 303 to sequence my 101 and modded out is great for that. Regular TD3 is unbeatable though and I have used original Roland tb303. Behringer comes very, very close. If you want a replica tb303 go for TD3

Manual is poor, this has full devilfish mods and needs more information. The orginal develifish manual is available but you are left wondering if they have implemented the mods in the same way. For example the orginal 303 has 1-5ms delay after gate, the devlifish has 0.5ms, have they done that? Does the soft attack setting change that? If you think you are getting a 303 'plus' the mods, dont buy it, as it's a different instrument really (but still very cool).
