The Aguilar DB925 is an analog bass preamp pedal built around a discrete all-FET circuit. Aguilar describes it as delivering "powerful broadband boost in a lightweight, space saving micro housing," and pairs that boost with what the maker calls a "musically sculpted two-band EQ" that adds body and weight to the low end12. It sits in the DB line of pedals and follows the DB 924, which Aguilar names as its inspiration1.
What it does to your sound
The DB925 is a preamp and EQ rather than a coloration pedal: its job is to shape and strengthen the signal a bass already produces. The two-band EQ works with broadband boost, meaning each control lifts a band of frequencies around its center point rather than a narrow slice. Guitar World's reviewer described 18dB of broadband boost from the bass control at 40Hz and from the treble control at 4kHz2. Because the bass boost is broadband, turning it up also affects the low mids, and the treble control likewise lifts the upper-mid frequencies around its center2.
The maker frames the EQ as a way to "enhance any bass you run through it, adding body and weight to your low-end"1.
Controls and connections
| Control / connection | What it does |
|---|---|
| Bass | Broadband boost, +18dB at 40Hz; frequencies around this point are also boosted, so adjusting it also affects the low mids2 |
| Treble | Broadband boost, +18dB at 4kHz; frequencies around this point are also boosted, so adjusting it also affects the upper-mid frequencies2 |
| Input | 1/4" in2 |
| Output | 1/4" out2 |
Power
The DB925 runs on 9V DC, center negative, and draws 3.5mA12. That current draw is light enough that it poses no burden on a standard pedalboard supply. Both the maker's listing and Guitar World's review give 9 volt DC as the power requirement12.
Size, build and price
The pedal is housed in a micro pedal format, and Guitar World's reviewer counted the limited footprint on a pedalboard as a positive aspect, alongside what they described as sturdy build quality2. The listed price is $1492.
What reviewers said
Guitar World's review found the DB925 strong in use: "In operation, the unit's sonic performance is impressive, adding more presence and power to the bottom end, tightening u" the mids with detail and definition in the overall sound2. The same review notes the pedal is made in the USA2.
From the DB 924 to the Silver Anniversary pedals
The DB925 carries the DB prefix Aguilar uses for its preamp and EQ pedals, a line that includes the DB599 and the DB316 Mid EQ Micro Pedal. RockBoard's PedalPedia says the DB925 was inspired by its predecessor, "the legendary DB 924"1. Guitar World places the DB925 within Aguilar's recent range of Silver Anniversary pedals, which celebrated the company's 25th anniversary2. Other pedals in Aguilar's wider range include the Tone Hammer preamp, the AG Preamp, the OBP-3 onboard preamp, and effects such as the Octamizer and Filter Twin.
For a player comparing options, the DB925's distinguishing points are its all-FET analog circuit, its two-band broadband EQ, and a housing small enough to fit where a full-size preamp would not12. It belongs among preamp pedals for bass, alongside Aguilar's other bass pedals.

Questions
What power supply does the Aguilar DB925 need?
The DB925 runs on a 9V DC power supply with a center negative connector, the same standard as most pedalboard supplies. It draws 3.5mA, a very light load that is easy on any supply or daisy chain.
Is the Aguilar DB925 analog?
Yes. Aguilar describes it as a discrete all-FET preamp, and Guitar World's review likewise calls it an all-FET broadband bass preamp pedal. There is no digital processing in the circuit.
How is the DB925 different from the DB 924?
Aguilar says the DB925 was inspired by its predecessor, the DB 924, and presents it as that pedal's successor in the DB line. The DB925 arrives in a micro housing with a two-band EQ and broadband boost.
Where is the Aguilar DB925 made?
According to Guitar World's review, the DB925 is made in the USA.
How much boost does the DB925 give at 40Hz?
The bass control offers 18dB of broadband boost centered at 40Hz, according to Guitar World. Because the boost is broadband, frequencies around that point are also lifted, so adjusting the bass control affects the low mids as well.
