JRC4558D

[Tim Curtis]

Hi Everyone -

I know that this is a little off-topic, but a friend and I have been
playing around with a couple of old Ibanez Tube Screamers.  It turns out
that one of them is a reissue that uses a different Op Amp than the
original.

According to several sources on the web, the original chip is a
JRC4558D.  I find it hard to believe that the difference in tone is that
great, but I could easily be wrong.  I'd like to replace this one with
the original chip.

Does anyone have some of these around?

Thanks,


Tim
