Teach me about LFOs

[BuddytheReow]

About to dive in to some tremolo/vibrato circuits. Can anyone share some links about LFOs, what they are, and how they interact with various circuits, meaning what part does what?

This would be a good start.

LFOs - part I

LFO stands for Low Frequency Oscillator. We use LFOs in modulation and delay pedals to vary some parameter, such as phase, volume, delay time, etc., to create movement and give our guitar signal more life. Oscillators are a really interesting subject and they're all around us. You're probably...

LFOs - part II - sinewave LFOs

In part I, I discussed triangle wave LFOs. This time around we'll talk about sinewave LFOs. Sinewave LFOs show up mainly in Uni-Vibe type pedals, a few tremolo pedals and amplifier tremolo circuits. All of the ones I've seen are based on the classic phase-shift oscillator. To get a sinewave...

Should have looked at Chuck’s stuff first. Thanks
