It's a real poser.
I talked myself into a Stomp. Parallel routing being the clincher.
However, I can't get past individual stomp boxes. I just like them. They're expensive, and fiddly and need a sorts of extra bits and bobs but I just love them. The designs, the simplicity, the occasional unexpected gem like the Prunes and Custard, or the SY-1. I might try a trade for a Helix FX but I'll probably just sell it.
