Reddit reviews Ernie Ball Black Polypro Guitar Strap (P04037)

Any is fine. It's just preference. I use this on most of my guitars.

How are you a guitarist with a gig in a few months but don't have a strap?

You're right, the instrument does not factor in as much as one's interest. Totally right.

Of the packages listed, the first Yamaha one for $159 looks very nice. You'd definitely get more than your money out of it. Yamaha has a great rep. for longevity.

I own this Rogue for $79 and love it to death. I taught Grade 6 and students were allowed to play whenever they wanted - it never got any rest from students or teachers.
I'd get this Snark tuner, this guitar strap, these strings, this string winder, and finally this stand. Oh, and these thin picks.

That gives you a grand total of $119.24. I've either owned or used all of these products and can vouch for them.

Now, the other thing I'm thinking of... there's this instructional book on Google Books, where you get the first 64 pages for free. It's a great resource, but the name escapes me. If I think of it, I'll write back. I hope this helps.

I had to look it up. Ernie Ball.

I've been using the same $5.00 Ernie Ball nylon strap every day for last 15 years. For ten of those years it was on a very heavy bass guitar. It's a bit worn, but I've never had a problem with it, and it shows no signs of failing anytime soon. Assuming they haven't changed their manufacturing since then, I'd advise OP to check it out.

This amazon link says both 68 and 72 inches.

I've got one. I'm 6"4' and play my guitar impractically low down, and I still have plenty of leeway on this strap. It's the only one I've ever found that goes to the length I like.
