Hello. I just got a hammer bass guitar from a friend and I realized that the bass sounds so low even through an amp. He told me someone rewired it from active to passive due to battery issues.
How do I rewire it back to active. It's a 4 knob bass; volume, blend, treble and bass as well as a G&B 2 band preamp in it. Thanks. The circuit currently looks like this.View attachment 4391824
