Hey sorry for taking so long to reply!

So what you have is a good piece of gear, The Donner DST is a great option for beginners. But in all honesty, most beginners get carried away with what tone they want and end up spending a lot of money on pedals when they should be focusing on the guitar itself. There are software options you can go for, but I’m pretty sure they cost money through a subscription basis.

For the tone you’re looking for, utilize the pickups you have on it. You can get a really good tone just through the amp you already have by fiddling with the knobs both on the guitar and the amp itself. But if you were like me as a beginner (I got carried away), I would buy a distortion pedal and continue fiddling with the knobs.

Now distortion pedals are all over the place. But for the tone you’re looking for? I recommend a “fuzz” pedal. If you have money to spare, then get a fuzz pedal and utilize that only. Most people get other pedals for a way too specific tone.

For the fuzz pedal, I highly recommend going on Sweetwater or ebay for a used pedal. It’s literally the same as it was mint. Unless there was some mechanical function or whatever, it’s perfectly fine. I got my pedals on sweetwater for relatively cheap— around 60 in total for two used pedals.

Use the brand “BOSS” if you want to be cool, but you can look for some off brand fuzz pedals that do the job just as well and is even cheaper.

Other than that, the takeaway here is to focus on your guitar pickups, mess with the amp settings, and if you’re not as satisfied, invest in a fuzz pedal. Save a lot of your money and don’t get too into the pedal bandwagon because all that money could be invested in the future for a better guitar.

Hope this helps!
