CA3260

Says bipolar in the data sheet. Looks a lot like an upgraded OPA207, so chances are good I’ll like it and find it useful for some of my onboard preamp designs.

The sheet does say bipolar for the input, but it also states the input impedance is 9M when used differentially or 300M when used in common-mode.

Have you scoped the clipping behavior? There are a lot of interesting hybrid formats these days, looking forward to checking them out in any case!

I've not put them on the breadboard and scoped them yet. Too much currently going on in the house with remodeling, floor sanding, painting, etc.

I still have yet to test out the MBB 3PDT Gorva stomps too.

I used the LMC6482IN for drop in replacement of the CA3260E in Ibanez mostortion, I also used the quad version of it LMC6484IN (which is half the price of the dual version for some reason) with satisfying results in other builds, I probably wouldn't hear the difference with any other drop in replacement such as TL072 tho

N-N-N-NECRO BUMP!

A great replacement with FET input and CMOS output is a TLC072, available from Mouser. These types are extremely low noise - not just low voltage noise but also extremely low current noise. I love the TLC072, use them often.

[Note added] I have used TLC07x's to lower the noise in some of my pedals, substituting them for other noisier ICs
