Tl072 low power replacement

Hi guys. I'm building a summing amplifier to mix a multi coil pickup. Since my bass already has another circuit preamp in it I was thinking of using something that performs as good as as a tl072 but with lower power consumption and same or less noise.
I would appreciate any suggestions.
Thank you

A TL062 is the low-power version of the TL082. The TL072 is the low noise version of the TL082. So, you'd save power consumption, but possibly introduce noise.

You might also consider the TL022. It is slightly different, but still a dual op amp with the same pinout.

I thought of the tl062, but if noise would be a problerm, which I don't know if it would, I would prefer to pay a bit more and get something else, maybe a newer opamp with better specs for the intended use.
Unfortunetly I do not know of what's been released nor or where to look. I have used the Tl022 before as a replacement for the tl062, I belive for LFO.

I had to read it about five times thinking "I've never heard of a multi oil pickup".  Right about the time I figured I'd missed out on a new wave of technology (like the Fishman Fluence) it occurred to me it was a typo.

I'll now crawl back under the rock I emerged from.

How loud is too loud?  What?

This technology is not new, is quite old in fact, it just never picked up.
