I'd swap the outputs, to that the first one goes to the audio and the buffer goes to the VU meter. Each op-amp will add some noise and distortion, even if it's only a tiny amount, better to have the cleanest signal going to the audio.

well ok. I thought since the VU meter already had an op amp it didn’t need another one. But I see your point.

 

The output of your first opamp can drive all the the rest of the pedalboard and the second opamp is not needed.
The input resistance of your first opamp is only 100k but it can be much higher.

The opamp in the VU meter is a "precision rectifier" with a small amount of gain. It rectifies the AC audio into DC and its opamp cancels the forward voltage of the rectifier diode.

 

Do a TL071 would work then. Thanks!

Technically, since the diode is in the feedback loop, its forward drop is reduced by approximately the open-loop gain of the op amp (which typically is very high), effectively making the forward drop negligible.

R2 is not usually included in a precision rectifier circuit.
