Is the 2N5089 Transistor (NPN) a JFET?

Nope.

I don't do this very often, but.....
LOL! ;D
I never really studied electronics. I just wire up electric guitars. I took radio in high school for one year. But I don't remember much of what I learned there.
So what kind of transistor is a 2N5089? I have a B.C. Rich preamp in my guitar and I just trying to understand it a little bit better.

Well you probably won't remember what people here tell you here either, some people are just destined to be google'ites.

Whenever you have a question about a part's nature (like what kind of transistor it is), google the part and find the datasheet. It's a document that explains all of the important characteristics of that part.
I googled it first. It doesn't really say.
Well, a datasheet for something that isn't a JFET is not going to say "this is not a JFET".
But the datasheet calls it an NPN amplifier. You already found that it's NPN. So then you wonder, what is an NPN transistor? If you google "npn transistor" the first hit (for me anyway) is Wikipedia's page on bipolar junction transistors, which answers your question.
OK thank you. I was thinking it was a FET or Field-effect transistor.

Aww, that's a shame, they probably said in class.

here's some more transistors from the Mouser catalog ... the 2N5089 is listed on the left hand side ... a wise and economical choice .... i recommend buying in bulk and giving the ones that you don't want away as stylish christmas presents to your electrically inclined friends ... when ordering by phone, be sure to mention to the operator that you are using a "charge" card. :icon_mrgreen:

( christmas present hint #2: inexpensive, but colourful capacitors also make excellent stocking stuffers! :icon_mrgreen: )

In all seriousness, the NPN is the giveaway. BJT (bipolar junction transistors - the "old" type) are NPN or PNP with connections for emitter, base and collector (E, B, C). A FET / JFET / etc type is constructed differently.
The datasheet really will tell you this, but you must wade through a lot of verbiage and details. It will not jump out at you.

Well I guess it all depends on what "jumping out at you" means right?
They probably cover the whole BJT-vs-FET thing in that one year of radio in high school, but since you weren't listening try a quick look at the datasheets for the two kinds of devices, it kind'a jumps out ...if you look at them:

Also, that link DougH just posted is very good info ...if you read it.
first figure out what the basic differences are between an FET and BJT... then it will jump out at you.

This is the funniest damn thread I've read in a long time. :icon_mrgreen:
