Integrated Circuit

hey im really close to starting my first project yay

but i need to know if my local electronice store (radioshack) would have the IC i need

i heard it can be hard to find the rigt IC you need the one i need is a 4558 for the Ibanez Tubescreamer should i be able to find this there? if not where could i buy one

If you're not worried about the "mojo factor" of the original JRC4558D, then you should find it relatively easy to find another manufacturers 4558 op amp at a half decent electronics store.

Use a socket for the op-amp IC, then you can use almost any dual op-amp to get the circuit running, then update the 'mojo' at a later date.

alright thanks alot

will using a different op amp degrade the quality noticibly?

[niftydog]

Using a TA4558 as opposed to a JRC4558 for instance will not produce a noticeable difference IMO.

just try a couple. you might like (for example) a tlo72 better than a 4558

hey i think i'm actually just gonna buy off of small bear electronics it seems like they have everything i need to build this

this may sound dumb but the enclosures he sells for $13.50 will work for housing my project right?

also looking at the schematic i'm using (the one from tonepad for the ts808 tubescreamer) i dont see a switch for bypass how would i put this in? do they have it at small bear

thanks alot for the help

That enclosure would work very good for this project. And smallbear also has the switches you need, the easiest would be to use a 3PDT switch (Aron who runs this forum also has them for sale). As for wiring them up there is a own project at Tonepad found here: http://www.tonepad.com/getFileInfo.asp?id=76 which should explain it for you. Scroll down and you will find the wiring shematic for the 3PDT switch.
Good luck with your build!
