Independent shopping perspective
Designed around fast, modern bass work, the Pro-Mod San Dimas Bass PJ IV pairs an alder body with a slim, graphite-reinforced bolt-on neck and a maple fingerboard shaped for comfortable movement at quicker tempos. The DiMarzio Model J bridge and Model P middle pickup arrangement covers punch, warmth, and midrange growl, with pickup blending and active three-band EQ for further shaping. Jumbo frets, a compound-radius board, and a deeper cutaway keep upper-register playing accessible.
