Intellijel Designs VCO 1U

This VCO is almost as basic as it gets - sine, triangle, sawtooth and square wave outputs and CV inputs for pitch and sync.
However, what makes it even better is that you can switch the octave range AND you can turn it into an LFO! Which can still be controlled with CV, which means you still get 4 LFO outputs of different waveshapes.
Considering how tiny it is, it is a great modules with lots of features.

Also, even if the VCO waveforms are basic, it still sounds great!

I have a Palette 104hp by Intellijel and bought this one as well as a bunch of other 1u modules to cover some gaps in the 1u line. This small VCO is really useful - from clean sine wave (that you might always need for FM synthesis) to the LFO mode - it finds its place in almost every patch.
