Excellent suggestions and advice, very much appreciated.
I will be using it (mostly) for synths but still want to reserve the ability to run whatever else into it (mics/guitar/drum machines etc)
And it will be for studio use not live use.
Cost is definitely a factor at the moment, I was initially going to build a modular FX box instead (I haven’t ruled it out) because there are some incredible effects in eurorack but I speced out a 6U 104hp all effects modular of modular effects that have been on my wish list for years and it was just around the $5000 mark which is way out of the question for the foreseeable future.
If I go down the pedal rabbit hole I am definitely seeing a lot of boutique stuff that I like but I like the idea of throwing a bunch of cheap pedals together to get things started
