The first classic rock band I ever joined had a fairly nice Shure in-ear system, but nobody knew how to use it. This was around the turn of the century. It put me off in-ear systems.
We had electronic drums and no back line at all. i did learn that when all the crowd hears is the FOH, the sound can really be amazing. But the bad is that the buds had no bass and I often could not hear myself - at all. On one song at a gig I discovered I'd been playing the song two frets off for who knows how long.
They were always hopelessly distorted and nobody would listen to my comments about over driving the transmitter.
Fast forward to this year. I just joined a band that uses in-ears and uses a separate channel to power the one monitor that I use. They have suggested I only bring a DI and the bass can be in the FOH and that monitor. It got me thinking, if one of the aux out channels is dedicated to me, I could get an in-ear system for me and custom set the volume for every input. So I checked amazon.
I was shocked at what has happened to pricing and quality. I had no intention of actually buying anything, but when I saw what might be had, I spent a few hours reading reviews and articles and pulled the trigger. We'll see if it matters. One great thing is that I'll have complete control over what goes into my feed.
And this means I am again in a band with no back line, though we do use accoustic drums. The kick is miked and I'm hoping the rest of the kit bleeds into the rest of the mics. If not, I may pull out one of my studio condensers to feed only the wireless aux outputs.
