I’m a big fan of DI: conceded defeat on the “power race” within the band a couple of years back when we bought a 2.5kW PA with full mixer, crossover etc, and got a volunteer sound guy at the same time. My Ampeg SVT-2 / Mesa 2x15 rig could cope with it, but the sound guy was pushing hard for me to DI so he could control the mix, so I grudgingly gave it a go. Everything else miked; drums (x3 mics), guitar amps (x2).
I wanted to keep valves at the front end at least; so initially used an all-valve Retrospec Juice Box active DI also feeding into a small digital head (Yamaha BBT-500H) / 2x10 cab on an amp stand acting as a stage monitor; pumps out enough for the whole band to hear it on stage, which is crucial. Now using Molan’s old Eden VT-40 with built-in Demeter preamp; nice fat DI sound, bags of on-stage power (still with the 2x10 / amp stand), and almost as compact as the digital head. I probably get more good comments about the bass sound now than when backline-only – the PA definitely throws it deep into the audience and the crossover helps keep it defined.
Biggest beneficiary has definitely been my back! Transport easier too – all fits in the back of the crappy small family hatchback. The 2 guitarists are still using their 4x12 full stacks though even though they’re miked up, as it “looks right”!
