Agree with the advice to go with a 4-banger. A lot more options for decent inexpesive fours, and as mentioned above, the low B tends to be a weak spot on lesser 5-string basses. If you are looking to record, I would also recommend going with a P-style bass. Simple and record very easily...
Very professional looking build! Finish turned out great, and as noted before, that neck just looks awesome! Would love to see progress photos from the build! Also looking forward to seeing what you come up with next.....
