Depends exactly what you want - to strip a bass is every easy heat gun, sand paper powered or otherwise and a bit of elbow grease and patience.
Depending on the wood you may need to grain fill which can be tinted or not and then it’s your choice, natural or colour.
Within colour there is of course block metallic, sparkle, swirl, burst all achievable some more difficult than others.
If you want a simple block colour finish of good quality, it is very easy to achieve yourself with a good quality nitro can - there is a lot you can do yourself, even the stripping to decrease cost if you don’t want to spray.
Whats the worse that can happen if you spray wrong? You sand it back and go again!
