Hey there. Wow after 21 years playing bass this is going to be really embarrasing but... I need a quick primer on outboard preamps. I have never owned one, though I own an old Boss EQ pedal. Is that even comparable? Here are my questions: 1) What are some good value outboard preamps that are easy to use in conjunction with passive basses to get a more active sound? 2) Do I need to get a bass preamp specifically or can I use a generic pre-amp, i.e. a guitar preamp. 3) What should I look for and listen for when testing preamps? 4) Are there any substitute outboard effects/electonics that you can use in lieu of a preamp? Thanks.
