Can you build a functional pedalboard for yourself using only one brand?*
I recently played around with this idea on some of the pedalboard planner style websites. There's only a handful of brands that have a deep enough bench to cover most pedal types, excluding the more far out niche noisemaker stuff. The main contenders are the most obvious, Boss and EHX. Some of the more "boutique" brands have impressively well stocked lineups in some areas, but are light or totally lacking in others. So it really depends on your personal pedal focus. There are some brands that only have certain modulation style pedals in combination with other types of effects. Some brands have several fuzzes, but no distortions, some have several overdrives and few fuzzes, some only have modulation in combination with other effects. So there's a lot of possibilities depending on personal taste.
Most production and well known boutique brands are covered between these two:

So, imagine your eventual sponsorship deals and post your creations!
