This question has been asked a lot id assume but I am a classical player originally but need to purchase my own upright bass preferably an electric upright bass since it’s more affordable and can work for electronic side projects but I am going to be playing Psychobilly style bass in a bit of a slower punk/riot girl band aswell as wanting to do some bluegrass and electronic maybe jazz and need something maybe that is less than $600 but the things I have found are all sold out I was looking at a Palatino 550 just as a starter but I’m not sure if it will be accessible. Is there any very cheap recommendations that can work for Psychobilly slap bass well and also what strings would be good to use for this on an EUB? Any advice from upright players for what you think I should know would also be very appreciated!
If you become serious about PsychoBilly (PsyB), the double bass you get won't just be a double bass, it will be one that is strong enough to repeatedly step on and dance on as you play, and your technique will include serious slap. While I am not a PsyB player, it happens that my double bass, an Alcoa, is one that would be sought after for PsyB music because of its strength, so I'm a little familiar with it. You might get away with an EUB for casual PsyB, just like you might also get away with a bass guitar, but serious PsyB players tend to use strong -- at least ply -- double basses. BTW, the recommendation for a Vic's pickup is a very good one for this genre (and a lot of others).
Since treatment of a double bass for serious PsyB and RaB is a little rough, if you're honest about it I doubt if you'll be permitted to borrow a standard double bass for this, and even rentals may be hard to find. Most standard double basses are really not intended to be stepped on.
If you become serious about bluegrass, there again, an EUB isn't going to work; bluegrass folks have a strong preference for acoustic instruments, including double basses. I've seen a few EUBs on stage with bluegrass but only in a situation where the performer had to fly from somewhere and therefore had to compromise and bring a more portable amplified instrument, but on stage they do tend to get negative comments no matter how well they are played, and for most bluegrass jams any amplified instrument would be a serious target of complaints.
I have seen a number of top jazz performers using EUBs; I'd guess you wouldn't have much if any problem with an EUB in that context.
Worth mentioning, a decent EUB -- especially one you want to use the bow with -- might cost you as much or more than a nice used ply double bass.
