As I mentioned earlier in the thread, make sure to budget not just for the bass, but also for essentials like a practice amp or headphone amp, cables, strap, tuner, maybe a spare set of strings, and ideally a visit to a guitar tech during the return window for a proper setup and evaluation.
If you're on a tight budget, a clip-on tuner will work just fine. Technology has improved enough that many multi-effects pedals under $90 now include tuners, making a $100 standalone tuner pedal unnecessary for beginners. Clip-on tuners from brands like D'Addario, Korg, and Snark can be found for under $30—some even under $20. Also keep in mind: if you buy a tuner pedal and already have an amp, you’ll need an extra cable to hook it all up.
Don’t overlook the importance of a proper setup. A tech will usually inspect the instrument and make essential adjustments—like the truss rod, string action, intonation, pickup height, and possibly nut filing. They’ll also check for any loose or scratchy pots, switches, or jacks. As I mentioned before, budget basses like the TRBX174 often come with low-quality, generic Chinese strings. If you plan to upgrade to better ones (like D’Addario or Fender - there are many options), bring them with you to the setup so the tech can adjust the nut if needed.
