Can a talkbox be used on any synthesizer?

Yes, a talkbox can be used with any synthesizer, provided that the synthesizer has an audio output and the talkbox can be connected effectively to it. The talkbox works by sending the audio signal from the synthesizer through a tube that the musician shapes with their mouth, allowing them to modulate the sound. However, the quality of the result may vary depending on the synthesizer's sound design and capabilities. Overall, as long as the necessary connections are made, you can use a talkbox with virtually any synthesizer.
