Is there a pedal that functions like the preamp on an active bass? I mostly play a Lakland which is active which I play through an Ampeg Pro 7. When I play my Squier P bass the volume is less and not as full as the Lakland. I am looking for a pedal to boost the P bass up to the level of the Lakland so I can switch guitars without having to adjust the amp. Not really looking for any effects from the pedal and I should be able to turn the pedal off and pass through when playing the Lakland.
