The bigger the gigs you play, the higher-powered your speakers will need to be. When the crowds and the venues push you beyond your trusty combo amp, it's time to build yourself a speaker stack worthy of a bass guitar legend. Working together with your choice of cabinets, a hybrid bass amp head can help you extract the most powerful sound out of your instrument to fill some of the biggest venues from floor to ceiling with rich, resonating bass.
Tube amps and solid-state amps each have their own advantages and characteristics. While some bassists may debate which is better, a hybrid design offers a simple solution: why not both? Generally speaking, hybrid bass amp heads will use tubes in their preamp section and solid-state hardware in the power section, which means the tone is shaped with all the vintage depth and character of a tube, then boosted to speaker-driving power levels through the clean, precise effect of solid-state parts. The result is a naturally warm, rich 'tubey' sound with the clarity and reliable performance of modern electronics.
One important point to consider when choosing any amplifier head is that it's a good match for the power rating of the speaker cabinet it's going to drive. If the wattage of your amp is more than the drivers can handle, you run the risk of a blown speaker. If it's too low, the speakers will be underpowered and the sound can fall flat. Make sure to check the amp head against your speakers' recommended power, and keep in mind that the output is different at 4 Ohms than it is at 8.
Finally, be sure you pay attention to the equalizer, adjustments and effects built into the amp head. These give you the option to fine-tune your sound even in the middle of a performance, and some amps even have built-in pre-sets so you can dial in a specific soundstage at a moment's notice.
There are lots of hybrid bass amp heads to choose from, so take your time to compare the units that interest you to make sure you pick the perfect one. With the well-balanced character of a hybrid design at the top of your stack, you'll have an amp setup that will make even your band's guitarist jealous.
