My FOH engineer's favorite DI is actually mine. I have to arm-wrestle him often to prevent him from re-purposing it for acoustic guitar, just so I can benefit from its great tone with my bass. Rupert Neve is a legendary audio electronics engineer. He shares his magic with "regular musicians" like me in this DI. My 5-string basses sound just how I like, with their tonal characteristics preserved and well represented in a mix.
