Tube Bass Preamp

Congratulations on purchasing Aguilar Amplification’s DB 659 Tube Bass
Preamp! The DB 659 is a warm and full sounding preamp. It is lightweight and

fills only one rack-space. Although the tone controls are simple and easy to use,
the DB 659 is a versitile unit that sounds great with any style of playing.

In addition to outstanding performance with any active or passive four string bass,
the DB 659 will musically and accurately reproduce the extended range of modern
five and six string basses.

All Aguilar products are hand made in N.Y.C.
