I'm looking to retool my board a bit, and I've got some questions for those who've sampled more stuff than me. Some of my favorite sounds come from boost pedals. In most cases, I prefer a few stacked boosts to an OD pedal. But my understanding of what boost is would indicate that it's a very simple, linear concept. Beyond silent switching and a clean circuit that doesn't add a ton of noise, I don't fully understand how one boost can be THAT much better than another. Why then does the price of boosts and preamps range from fifty bucks (or even less) way up into the hundreds? Should I look into things like the Benson Preamp, or a Supro boost, or should I just get a TC Spark and spend the difference elsewhere? Can anybody educate me on this subject?
