The Strymon Ojai power supply is also good - it solved my noise problems with digital pedals.

The Walrus Slo is a pretty cool reverb for those big soundscapes. Boss Tera Echo is neat. I like having a look around at my local shop to see what is on offer used - got a nice deal on a Polymoon a while back.

Processing guitar with Eurorack can be pretty cool too - any filters and effects maybe modulated with an envelope follower or something. But that’s not quite as fun somehow as seeing those little Boss guys on the floor.

BTW both of us here just put the pedals on the floor or a table rather than having a board built out. I never have more than three hooked up at once. Less confusion and you avoid needing boosts or buffered bypass or whatever. Plus it’s easier to move stuff over to my synths.
