Opamps: It would be cool to have a list...

I've got a bunch of oddball op-amps (at least to me) ones I haven't seen in pedals. It would be nice to have some sort of list of what op-amps are good for effects building and what their characteristics are. We know the common ones like 4558, 1458, 741...

Here are some I don't have experience with:
KF353
KA358
CA3260
TL064
LM386

Maybe some of the "Elder Statesmen" here could share their expertise?

TT

KF353 = LF353 dual opamp by National (FET input)
KA358 = LM358 dual opamp by National (~ LM1458)
CA3260 = dual opamp by RCA (now Harris)
TL064 = Low current version of TL074 quad opamp by Texas
LM386 = noisy junk single "opamp" intendened for use as a small power amplifer in transistor radios.

Mr. Divos hates the 386, with all his spirit.

Looks like the KA358 and KF353 could be useful for effects building.

The x-ref for the CA3260 shows up as a TLE2141 which mentions use for "high-fidelity audio"

Does anyone have experiences using any of these devices?

Guess I should toss the 386's

Nooo, don't toss them, you can try some cool circuits with them.

I hear rumor that the CA3130 is super-cool. I ordered some to find out.

I really like the LM301 because it's externally compensated so it's easy to play with... they're also incredibly cheap and easy to find.
The LM833 is kinda cool... I have a couple, but haven't messed with 'em much.
The LF411 is probably my favorite "hi-fi" single opamp. It has a high impedance JFET input and low noise. There's a dual version called the LF412; I got a couple recently, but haven't played with them yet.
I like the NE5532... it's a dual that's sort of like a higher quality 4558; lower noise and more fidelity.

Good Info Yall,

I was digging thru old parts and found the guts of a Sunrise Acoustic Preamp which uses an LF441CN

I'd like to find a use for some new opamps I've recently acquired some LM4562's. Datasheet says:

Dual High Performance, High Fidelity Audio Operational Amplifier

General Description
The LM4562 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully
specified for high performance, high fidelity applications.

Tried in a newly built Zendrive, didn't even make a noise.

If you've got a handfull of OP-Amp ICs that you've collected and want to use for building stompboxes with, I'd recommend googling for datasheets for the ICs, sometimes there are some cool circuits supplied with them...
