Hi stratmanjimbo,
I love pedals. I'm so glad you asked. The first pedal I ever bought was a tube screamer. They're all clones of the Ibanez Tube Screamer at this point, which I believe was the original pedal. There's just something really nice about having that hairy but not too crazy distorted tone. The Ibanez Tube Screamer can cost hundreds of dollars. But you can find a cheaper clone for less than $100. Google em, search through Youtube for reviews!
The second pedal I bought was a delay pedal, and it was kind of crazy. It has the ability to loop two tracks and it also has a handful of fun effects to play with. It just works. Here's a link: https://www.sweetwater.com/store/detail/LilLooper
If you're okay with your guitar tone and want to experiment, I suggest getting some type of delay pedal or a loop pedal if you just want to jam out with yourself or create some new stuff.
Sorry, I'm ranting!
Goodluck!
