IMHO when size allows but offer the option to delete the DI and associated complexities of IR and HPF/LPF filters for those that do not want or need those features.
My feeling about all in one boxes is well known, tldr they all have shortcomings no matter how well designed or intended.
And I'm open to that to a degree. It all comes back to my trying to please everyone all the time with every pedal, I'll try to do it as much as it makes sense. But this all falls under the umbrella of customization to me. Every pedal will have a "stock" configuration. A stock Grand Slampegg will have a pink LED and be in a silver powdercoated enclosure with whatever artwork I decide (probably carry over or slightly modify the honeycomb design from Slampegg Bee), and it will have a D.I. That will be the stock configuration that I will build and keep on-hand. For logistics reasons I have to choose one configuration and let the other options be limited to custom orders, or I'll lose my mind.Very valid. Sushi is an interesting phenomena in that the devoted have multiples of these pedals on one board. In that context it does not make sense. However I'm thinking of the "average player" and how they might utilize a Sushi Box pedal, I bet many of them would only own one and those that know what's up would probably use it as a One-Pedal-To-Rule-Them-All context if it had a DI. Sort of a realistic and reasonable Noble alternative (if I might be so bold).
I say this in the context of the type of bass player that shows up to a gig with two pedals... one is a tuner and the other is a DI.
I keep trying to add more explanation to this post and it keeps feeling like I'm ranting (surprising I know, I never rant), so I'll leave it at that.
