Well in that case that's probably an expensive itch that doesn't need scratching. I've already got a 374a in (IMO gorgeous) dark coffee burst that don't intend to sell, and the jump up to a P34 probably isn't worth the outlay, unless I got rid of the 374.
While the Japanese build is likely to be exceptional, the Indonesians are none to shabby.
Talking of cases, the standard gigbags with the 374 is very high quality for the price of bass. My BBPH came with the same bag.
Good luck with the P34 👍
