Hey Ian. This generator does not comes with a schematic so we don't know if a variable capacitor is used. However, it's worth noting that there are many other ways to achieve stable waveforms that do not require the use of variable capacitors. Like the generator in the video, this one also features an output attenuator.

This can work well for guitar amps, pedals, and other audio equipment. You may need to set it at the lowest setting on the attenuator if you are sending to inputs that are expecting instrument signal levels.

Generator functions well and does exactly what it should do. What more could you ask? I also purchased the matching RF generator. Review for that to follow.
