And this has been the big conundrum in Sushi Box's recent existential crisis. I love giving people what they want, and people will always want small, inexpensive, and good sounding, and I've been happy to provide, but getting all three of those in one box means there are some design compromises.
But at the same time, I love improving things, and I will continue to chase whatever version of "perfection" is floating around my mind any given week. Improving things means I'm designing out the compromises, getting ever closer to that elusive perfection. But with design improvements, as you can see, there is additional cost, both in size and in, well, cost.
The Deluxe series are my attempt to make "big boy" pedals, pedals with no compromises, pedals with no room to say "yeah, but..." This is a shift from my usual brand of "budget boutique", and I've been grappling with it the whole time I've been working on these. Finally is $250 because I want everyone in the world to own one. But Underground Deluxe took a lot more work to design, and I'm more proud of the results. My goal was to design something that 5-years-ago-Nathan would look at and wet himself out of sheer awe.
TL/DR - Sushi Box is still trying to figure out what it wants to be when it grows up.
