In Shelf Modes the Bandwidth has a special function. When this knob is fully CCW, the shelf curves are very similar to almost all other EQs. As you increase the Bandwidth control, you begin to introduce a bell curve in the opposite direction. So if you have a shelf boost, you gradually add a bell dip which modifies the overall shelf shape. At straight up, it stays flatter towards the mid range, and begins to boost further from the mids with a steeper slope but the final maximum part of the boost curve stays relatively untouched. With the Bandwidth control fully CW, that bell dip becomes obvious and is typically 6dB down at the frequency indicated. The boost slope is steeper and the maximum boost may be about 12 dB. These curves were modelled from Pultec EQP1-Asand largely responsible for the outrageous phatness they are known for. As you turn the Bandwidth knob CW, it seems as if the shelf curve is moving further towards the extreme frequencies, but mostly of this is just the beginning part of the slope changing and not the peak. This also implies, that you may find yourself using frequencies closer to the midsthan you might be used to. These shelf curves have never been available for an analog high shelf before and provide some fresh options

EQ TECHNIQUE
1The song and the vocals was what producers wanted and perhaps that hasn’t changed much. Bands were recorded with live vocals back then. Even overdubs were a band thing. Much of the signature of both the British or American sound were the vocal harmonies. Same today
Rather than try to do all your compression while recording vocals, save some for the mix. This takes a little pressure off of finding the “ultimate” compressor with perfect settings and you have the option of compressing the vocals as a group
Loops: The trick? Make the bad stuff sound good and the good stuff sound bad. Put it all together and go nuts with the mute switches. For that ol’ telephone filter, first try the two mid bands with deep shelf cuts. You might expect to just use the filters but these ones probably neither go high enough nor low enough for this purpose so use them in combination with those deep shelves
