I do have plenty of pedals and still get excited to try new things. Usually new gear brings the level of enthusiasm up for a while. If the gear sounds great/interesting to my ears it will excite me whenever I include it in my signal chain. I am not getting that much new gear anymore (I can achieve a lot with what I have if I just keep practicing, trying different combinations, and just using my imagination) and I am slowly learning that a new fuzz is not gonna sound much different from the fuzz pedals I already have. But then again the last pedal I bought was a fuzz :)
I have kept almost everything I have bought. I feel like if a pedal does not sound good then I am using it wrong or I should use it with a different sound source. Maybe one day I will realize it might be that a certain pedal just is not for me and I should pass it on. Looking forward to that day.
