TB-303 vs Behringer TD-3
The original is the reference. The clone is the practical one. Here is how to choose.
The short answer
If you want to own a piece of music history, or you can afford it, the original TB-303 is the real thing. If you want to make acid, a Behringer TD-3 gets you most of the way for a fraction of the cost, and it connects to a modern setup with USB and MIDI.

Who should buy which
- You make music and want the sound on a budget: the TD-3, or a software 303 first.
- You collect gear: an original, bought from a seller with a return policy and a condition report.
- You are not sure yet: start with the free emulator and a software plugin, then move to hardware.

Frequently asked questions
Is the Behringer TD-3 a real TB-303?
No. It is a clone made by Behringer. It aims to reproduce the TB-303 sound and layout, but it is a different product with its own circuit and construction.
Which is better, a TB-303 or a TD-3?
It depends on what you want. An original is a collectible with a lot of history and a much higher price. A TD-3 is far cheaper, adds modern connections such as USB, and is much easier to buy and replace.
Can I hear the difference online?
You can try the sound with the free emulator on this site, though it is not an exact copy of either machine.
