Good morning everyone,
I'm looking into building an OP AMP MUFF (PIG BUTT), and shopping for parts before I get the board.
Wouldn't want to get a board I can't assemble due to the lack of parts.
The build doc (link below) specifies 2 ICs: 4558 and LM741.

My access to parts is somewhat limited. All I have available are JRC4558D and LM741N respectively.
Could somebody please let me know if these versions of the ICs will work for this build?
Thanks in advance!
yes they will
Thanks for the quick reply drog_trog, I'll try assembling with these!
Rock on!

Good evening!
"All I have available are JRC4558D and LM741N respectively."
the JRC4558 is a dual op-amp. And the LM741N is a single op-amp.
op amps are very common in fuzz and distortion pedals. Next time you are purchasing parts/components,
stock up on op-amps. Depending on the price, I recommend five or six.
JRC4558D. JRC as a prefix, means that it is a standard 4558 opamp that was made by the Japan Radio Corporation. D, as a suffix, means that it is in a DIP8 package.
LM741N means that it is a standard 741 opamp, with the suffix N meaning DIP8 package, and 0 - 70degC operating temperature range.
LM as a prefix I'm not 100% sure of by now, since it seems to be used from a few USA manufacturers, like Fair Child and NatSemi.
When in doubt, look up the datasheet!

LM stands for linear monolithic. Linear is roughly analogous to "analog" in this usage, and monolithic as they use a single piece of silicon.

Learn something new every day :)
Kinda new to the hobby, hence the newbie questions. Thanks a bunch, much appreciated!

+1 I appreciate finally knowing what LM stands for.
