Op amp question

[dlazzarini]

I’ve been skimming through the goldmine of projects on the webpage and checking some part availability. My question is about the JRC4558DD op amp. I believe that was the coveted ts-808 chip if I’m not mistaken. I have a JRS2043DD that I removed from a ts-9 years ago. Can this be substituted for the 4558 in the Dwarvin Hammer without any noticeable difference?

Should be good to go but socket it anyway

Thank you

It should work fine. Any tonal differences should be subtle at best.

Kind of thought so thanks
