Just built my first CMOY and amazingly it works

. Typically how long does a single 9v battery last on a standard Cmoy?

Ahh, n/m I should really use the search button more often

Battery duration also depending on your opamp type, phones power drain ànd circuit design features

. Surely batt type is important too.

However average duration it's about one mouth, I think, if using is from time to time - 2-3 times per week (about two hours)

.

The amount of current used depends on the volume used. That is, higher volumes use up your battery more than lower volumes. You must take this into account to figure how long a battery will last.
