The Working horse of the pros. EBS Tube Definition (TD) heads have served big productions such as world tours with Bon Jovi, Kid Rock and Tina Turner, intimate tours with demanding bass players like Marcus Miller as well as loud and rough tours with hard working bands like The Haunted (with well over a 1, 000 gigs on EBS TD heads) or Danko Jones and is the most common EBS amp on the backline rental companies.

Natural and true. These heads also offer incredible tone; natural and true to the character of the instrument and personality of the musician using it.

660 W RMS. With 660 W RMS pure output power it will always rock the house. It is a Tube/Solid State hybrid bass amp. The tube in the Drive section warms up the sound and adds a nice natural compression and character of a tube amp. 

Full control. The front panel feature a Character filter, which is a quick fix to a mid-scooped overall tone. An input Gain control sets the input level from your instrument. The Filter Active button activates/bypasses the EQ filters. A shelving Bass filter for the lows. An advanced Middle filter lets you pick the frequency range you’d like to adjust with one control and cut or boost in that range with the other.

The clever “Notch” function is active when the Cut/Boost control is set to “Notch”. You can then identify and scoop out frequencies causing unwanted feedback with the Frequency control. 

A  shelving Treble filter and the unique Bright filter controls the highs.

The Drive on the TD heads can be set to Tube Mode (to connect the tube) and Boost Mode. Boost Mode boosts the whole frequency range when turning up the Drive.

Finally the balanced XLR output sends a perfectly balanced line signal to front of house or a studio mixing console without the need of an external line box. Choose between post/pre EQ, with our without Speaker Simulation and Ground lift.

Input jack Phantom Power option. If used with a stereo cable, the input jack offers 9V DC Phantom Power output, that can be used to power a single 9V DC EBS pedal or an active bass.

Back panel. On the back you’ll find the Effects Loop, featuring a Mix level control that lets you blend in the effects with your sound from zero to a hundred percent. Effect Return also offers the same Phantom Power function that you find on the Input jack at the front. A Tuner output to connect a tuner rack unit easily. A  Line out, in case you need the power from another amp to drive a second pair of cabinets. The Filter Remote Inputs to connect the RM-4 footswitch that lets you switch on and off Character, Filter Bypass, Drive and Mute from front of stage.
