I got this bass called the Aria Pro II Avante AVB TN5. It got pickups the size of a little chocolate bar. Mars-equivalent. If I want a BIGGER pickup I need to cut thought my bass. zz..... I have the original Aria Pro II pickups on them. I want a pickup with heavy and powerful sound for rock and metal and stuff. [although i'm starting to like jazz these days ] So what should I go for ? I got around 100$ to waste on this piece of wood. [an excellent piece of wood] I think there should be LOTS of pickup experts around here. I'm new at this.
