In this extract from the video ‘How to Listen—Pultec Edition’ Fab Dupont demonstrates the famous Pultec Low End Trick. you might have seen this before but was it using a plugin? Fab has a real Pultec.

Fab demonstrates the trick and helps you understand this counter-intuitive technique using a spectrum analyser and a noise generator to show the EQ curves which result from using boost and attenuate simultaneously on the low end of a Pultec equialiser.

How Does The Low End Trick Work?

I found this image in a very old blog post on the UA website: Analog Obsession: Pultec Plots. It illustrates what happens when the boost and attenuate controls are both active on a Pultec. The attenuate control creates a dip at the upper end of the LF boost, cleaning up the ‘woofiness’ which can result from large LF boosts. This clearing out of the top end of the bass/bottom of the lower mids is extremely well suited to kick drums and it is in this application that the Low End Trick is most commonly found.
