I've been leading worship from guitar for about 10yrs now, and I've gone through many phases as a guitarist: the expensive high-wattage tube amp phase, the monster pedalboard phase, the tiny pedalboard phase, etc. I'm now at the point that what I value most as an electric-guitar-playing-worship-leader is simplicity. I don't want to worry about which 2 pedals I need to step on during the bridge (while I'm still singing), I don't want to worry about remembering if patch #3 on my looper was the delay or if it was patch #4. I want to have good, solid, usable tone & effects that I can use without it being a distraction to myself or my church. So here's where I'm at... I have my guitar, with an intern delay unit (activated by toggle switch), into a Vox Amplug (AC30), straight to the board. I get my dirt from the amp, which I can have cranked because of zero stage volume. I control the level/dirt the old-fashioned way, with my volume knob and pickup selector switch. I get delay from the internal unit, preset to about 72 bpm (most every song we play is 72-78 bpm, oddly enough). I'm a huge reverb guy, but I began to realize that between the other guitar and keyboard, most of my sweet shimmer/modulated/big sky reverb was never making it to our church's ears. So I cut it. Delay does make it through though, and thickens up my tone for lead/atmospheric stuff, so I can live with a good analog delay (digital of course). It's built-in to my guitar because most of the time I'm singing, and I can't be looking down to switch effects on/off. I can guess where they are, but you can imagine what happens when I guess wrong. So that's my philosophy when it comes to the electric guitar-playing worship leader: Simplicity Through Complexity. In order to get to the simplicity of a single effect and great tone, I'm willing to put up with the complexity of building the effect into my guitar. When it comes time to lead our church in worship, my guitar & effects are the last thing I'm thinking/worrying about.
