Sure thing, just grab a solid entry‑level condenser mic like the Audio‑Technica AT2020, pair it with a cheap USB interface such as the Focusrite Scarlett 2i2 Gen 3, and load Reaper (free) with a budget bass plug‑in like TDR Nova or a simple EQ to boost the low end. If you want a physical bass boost, a small subwoofer like the Dayton Audio SUB‑12 will punch through. Just keep in mind that the cheaper the gear, the more noise and distortion you’ll have to work around—expect no studio‑grade sound from a $50 mic, so plan for some tweaking.

That’s a solid start, but remember the AT2020 is sensitive and will pick up all that metro hiss. Try a low‑cut filter before you hit Nova, and keep the sub’s volume moderate—those 12‑inch woofers love a lot of mid‑bass, so you might get a muddy low end if you push it too hard. Also, consider a little room treatment: a cheap DIY panel can cut a lot of reverb and make your bass tighter. Keep tweaking and you’ll get a gritty, urban vibe without drowning in noise.
