Narrative:
Aircraft X was being vectored for the RNAV runway 29R approach. I gave aircraft X a vector and altitude to maintain until established on the final approach course. The altitude was at 3;400. That is the lowest altitude available with the current MVA [minimum vectoring altitude] in that area. As aircraft X was descending for the crossing fix; aircraft X was descending through 3;400. I asked the pilot if he blew through his altitude. The pilot stated he was descending to 3;000. I reviewed the tapes and the pilot read back 3;400.hear-back/read-back error.
