The Aguilar AG Preamp puts the sound of the AG preamp into a pedal you can take anywhere.

Just remember that you will need to buy an 18V DC power supply separately.

If you want the classic Ampeg sound in a small box, this bass preamp is a good pick. It is an analog unit with a three-band equalizer, so you can shape your tone. It runs on a 9 V battery or a 9 V power supply, which you will need to buy separately.

If your bass has a two-band preamp, or you play a passive bass and want the mids to come forward, this pedal is worth a look. You can keep it on all the time as an EQ, or use it to quickly switch between two settings. It runs on a 9 V DC power supply, and one comes in the box.

If you play bass and want one box that handles boost, compression, EQ, and cab simulation, you will find plenty to work with here. It has a 6-band EQ, an XLR DI output for sending your signal straight to a mixing desk, and USB loading for seven custom impulse responses. Just plan on a 9 V mains adapter, since batteries will not power it.

The Phil Jones PE-5 is a bass preamp in pedal form, with a five-band EQ, a balanced XLR direct output, and a boost effect. It has a rechargeable battery that lasts up to 8 hours, so you can use it away from a power outlet.
