Active tone shaping from Aguilar!

Active electronics and preamps give you bands of EQ to shape your bass's tone. Using these active EQs lets you find your signature sound directly from your bass. Aguilar sets the standard for aftermarket onboard preamps. The Aguilar OBP-3 runs at 9V or 18V and is the most flexible onboard preamp/EQ Aguilar makes. You get three bands with 18dB boost/cut at 40Hz, 16dB of boost/cut at either 400Hz or 800Hz, and 16dB of boost/cut at 6.5kHz, giving you the fat tone-shaping you need. Expand your tonal palette with the Aguilar OBP-3.

Rated 4.5/5

very good little preamp

definitely sounds great, even with all the tone pots centered it effects the tone somewhat, not really distortion but adding a slight "growl" to the sound. the +/- 16db is a bit much and will clip most inputs with the bass at full. the only real issue i have with it is the wires. everything about them bothers me. firstly, they used silver wires, probably just so they can say "hey look we used silver wires thats why this costs $" when in reality, silver wires have no effect on the sound. then the wire sleeve, which is cheap hard plastic, that dosent cut but rather stretches, requiring you to use the clipper side of your strippers and be very very careful. said wires are also only about 4-6" long or so, so dont expect to sit this in its own little cavity and route the wires through to the control. the cheap hard plastic sleeves also make the wires very inflexible. overall sounds great, but its a p.i.t.a. to instal due to poor build descisions.

OBP-3TKPP

I've recently gotten a Bass Mods, M534, and I'm still learning how to use and adjust this combo. I just changed the strings and this Aguilar/Bass Mods Combo is Amazingly Responsive. I'm comparing to the Fender Jazz American Active Deluxe V's that I had. I get all of the same tones and Some Extras in both Passive and Active modes but Without the annoying 60hz buzz. The attack is more pronounced...

Going back to my Bartolini Preamp

Wiring diagram on this thing isn't very clear and be prepared to solder several wires... Took me forever to get it done! I would suggest you purchase this preamp prewired.
Anyways, as far as sound, it sounds very flat and lower overall gain compared to my Bartolini NTMB that I've swapped out. Bartolini sounds warmer and comes with gain trim knob to adjust the overall buffered output. Bartolini smokes this preamp in every category. Don't understand the hype about Aguilar products... Ive owned their Tone hammer 500 head and was not impressed at all with the overall tone and the annoying breakup sound I used to get from it. Stay away from Aguilar overpriced garbage. It's like jack of all trades and master of none business model. Bartolini is master on what they do. I highly recommend you look into Bartolini preamps.
