"It's all about the tone! The Neve is basically valve (analogue) tone channels that were made in the UK by Rupert Neve who used to make mixing desks. These days a lot of folks use these "modules" in racks to warm the sound of the guitar and other stuff whilst not actually using an old board as we all use computers and pro tools for 80% of the recording process but this helps really improve the sound of the guitars. The Trident A Range is similar and also from the UK back in the day."
