Tube Bass Preamp 

 
 
 

Congratulations on purchasing Aguilar Amplification's DB 680 Tube Bass Preamp!

  

The DB 680 is designed and manufactured to provide the most discriminating bass player 
with a studio and live performance tool worthy of a fine instrument.  The DB 680 
addresses the contemporary bass player’s needs in all studio and live applications, and is as 
effective for recording as a chain of the most desirable classic studio gear.  
 
The DB 680 has 

two fully parametric EQs

not

 semi-parametric, for complete tone 

shaping possibilities, a tube driven resonance circuit, tube effects loop, and variable 
balanced outputs.  For the road, there’s a great sounding crossover, -40 pre and post-eq 
outputs for the mixing console and footswitchable inputs and master mute (leaves tuner 
input on for silent tuning). 

The chassis of the DB 680 is steel, 

and can withstand the 

bumps and grinds of a tour.  
 
Most importantly, the 

ten tube stages

 make for a sweet, warm tone and smooth feel 

beyond compare!
