I often hear bass players say something along the lines of "I want to hear the effect when I turn it on," as in, the effect has to be obvious (sun-melting fuzz, cathedral reverb, for e.g.) or it's not worth putting on. A go-big-or-go-home kind of thing. I didn't use effects on bass until I picked up guitar, where, in my experience, a lot of effects are used subtly: slapback delays, light overdrives, small-room reverbs and so on. A clean guitar tone, it seems, is never actually clean. It's sort of the approach I took when I incorporated effects into my bass playing. I looked at boosts and light overdrives, not distortions. I toyed around with fast and low-feedback delays to make my tone "breathe," not The-Edge-dotted-eight type of delays. What's your take on subtle effects? What are you favourite subtle effects?
