So basically I'm new I'm still new to everything and have no idea what is wrong. I've been a bedroom player for about a year with my regular active Ibanez, which goes plenty loud with the amp I have. I recently got a Fretless Squier J, and I've began to notice that it is way too quiet. I max out the bass and my amp and it doesn't really help any. I'm still new to passive bass and I don't have a preamp, so I'm not sure if that has anything to with it. Any advice would be helpful. Forgive my lack of knowledge EDIT: It's a little hard to explain, but I'm pretty sure it has somethong to do with my input. I just took the plate off and pushed some of the connections a little better into place. So I plug It and and bam! Full sound. The problem is, when I went to screw it back up, the sound would die down and fluctuate depending on how tight i tightened the screws.. So any suggestions?
