Here is a quick blast. The guitar is The Baby - made specially for me when I was 18, it is now over 30 years old but is still one of the nicest basses I have ever played.
I don't talk because every time I tried that Custard barked at me!
I start off playing with a basic, clean, sound. Then I adjust one of the controls to give different effects.
The first is an envelope filter which gives a wah-wah effect.
The second adds another note an octave below the one I play.
The final effect is a chorus,which gives a swirling sound that is used by a lot of bass players.
Hope it comes through OK!
