Pedals you regret getting rid of?

Ok let’s do a classic here. What pedals do you most regret getting rid of or selling and why?

For me:

• Catalinbread Echorec. I love multi tap delays and while I was able to get close to emulating this on my DD-500 it’s just not the same. The way the delays blend into each other and create this wash of reverb is sublime. Probably going to buy it again soon.
• Boss DS-2 Turbo Distortion. It wasn’t that different from my DS-1 but damn I wish I still had it. Whenever I play my DS-1 now it’s just too harsh.
