The last few months a various range of analog and pseudo-analog gears came out. Some of them were sold as machines able to emulate the rather unique TB-303 sound.
Here are a few comparative sounds from those emulators (22khz - 8bits - mono). For each machines you have 3 types of sound, and those types are the same for all machines (same notes, at least ...).
