The Power and Tone to Rule Any Venue

Armed with a monstrous 750 watts at 4 ohms, the Aguilar DB 751 bass head gives you the headroom to rule any venue. The preamp section of this beast is juiced by three 12AX7s, while 12 complimentary lateral MOSFETs drive the output. The result is fat, round, tubular tone at stadium-shaking volume. To shape all this tasty tone, the DB 751 gives you gain and master volume controls, and the exacting EQ control of a passive 3-way tone stack with active midrange, plus bright and deep switches. Tone, power, and versatility - you can have it all with the Aguilar DB 751.

If you play a range of various-sized venues, Sweetwater knows you require a bass head that can do it all. Aguilar's DB 751 is what you need. With a bone-crunching 750 watts at 4 ohms (975 at 2 ohms), the DB 751 gives you the headroom to ace any size gig. Mate the DB 751 with one or two of Aguilar's excellent bass cabs. The DB 751 gives you the flexibility of two speakON connectors (with a 2-ohm minimum load), so you can mix and match cabs appropriately for specific gigs. In addition, for recording and going straight into a PA, there's a front-panel balanced XLR DI output with pre-/post-EQ and ground-lift switches.

Awesome tone and powerful sound-shaping tools

The Aguilar DB 751 delivers broad dynamic response, detailed note articulation, deep (but focused) low end, punchy midrange, and stunning high-end clarity. Dial up the gain control, and the three 12AX7s in the preamp section serve up scrumptious, classic tube growl. The DB 751 gives you the tools to shape your signature tone: a passive 3-way tone stack with active midrange and bright and deep switches further juice your sound-sculpting capabilities. The Aguilar DB 751 will give you the tonal mojo to sail through any show or recording session with flying colors.

Bass-savvy design and inspired engineering

Aguilar bass amplification is respected worldwide for its outstanding tone and reliability. It's the backline of choice for top bassists like John Patitucci, Gary Willis, Tim Lefebvre, and countless others. Aguilar designs gear by conceptualizing it from the musician's perspective and then presses on with inspired engineering. For starters, Aguilar is a team of pro bass players and engineers. In addition to bass heads and cabinets, the company also designs and manufactures preamps and pickups that are standard equipment in many of today's finest basses, as well as effects pedals, so they have a uniquely holistic approach to bass tone. Aguilar gear is built tour-grade tough in New York City, and it's road-tested to stand up to hardcore professional abuse. For bass players, this is as good as it gets. You simply can't go wrong with Aguilar.

Tone King

The Best amp I have ever owned. I love the simple tone controls and they deliver the tones I really want. The only complaint I have is the weight. However, when I compare it to an Ampeg SVT, the Aguilar is much better. This amp is also way more reliable.

Wow!!!! tone and power to spare

This amp is truly everything you hear about it. Right now I am using two DB112s with it so it is putting out 750 watts! This is so powerful I can add an addition 4 ohm cab and it will put out 975 watts! The tone of this amp is impressive. I play fender jazz basses in a blues/blues rock band and I dial in a warm punchy tone but his amp can literally shake the house! I bought the aguilar head case to protect it... Boss tweed to match the cabs so it's a great vintage look! I've owned more than a dozen bass heads of the years this is the last one I will ever have to buy! The sound of my dreams!!!!

DB 751 has power to spare. Well made and sounds very good. Not too heavy. Has just what is needed. I use 6-10" and 2-12" cabinets with it and it rocks when needed. A little pricey but appears to be worth it. Also super fast delivery time was nice.
