The ULTRABASS BX4500H is a massive 450-Watt bass amp head with patented* Dynamizer technology, boasting a switchable Ultrabass sub-harmonics processor for unbelievable low-end power and a revolutionary Shape filter for extreme sound range. Since flexibility has become a particularly important factor in the music business over the past few years, modern bass players need to offer a broad range of sounds, but should still be able to play in different kinds of settings at short notice: home recording, studio or live concerts.
This is why you get a complete set of useful functions that are simple enough to be operated intuitively and quickly. An extremely musical 5-band EQ with “Bright” and “Deep” functions gives you the ultimate in tone-shaping. There is an integrated limiter and an active, temperature-controlled cooling system for ultimate protection. You also get a vintage-style VU meter for precise signal level control. A dual footswitch for Ultrabass and Shape functions is included, and there are 3 speaker outputs on ¼" jack and touch-proof connectors compatible with Neutrik® Speakon®. With this amp, you can certainly rock the stage like a pro!
