Tips

To get the most out of your EQP, experiment with the classic Pultec trick: boost and cut the same low frequency simultaneously to create a unique EQ curve that tightens the low end while adding depth. For vocals, a gentle boost at 12 kHz can add air and presence, while a slight cut at 100 Hz reduces muddiness. Always allow the tubes to warm up for a few minutes before critical listening to ensure stable operation.
