90 Watt All-Tube Amp!!, Classic Design & Layout. Volume, Bass, Treble & Presence Controls. Specially Designed Transformers.


The EBS Classic T90 is an all-tube bass amp developed by EBS and experts with more than 20 years experience from building exclusive tube amps for Hi-Fi and guitar.

The end result is a hand-build tube-amp with specially designed transformers and selected and matched tubes.

The 90 tube-Watts make the EBS Classic T90 a perfect amplifier for the studio, especially since it comes with a direct driven balanced tube output. This amp is also very well suited for use in live situations -- and a perfect companion to the matching EBS ClassicLine cabinets.

The specially designed transformers are overdimensioned with all materials carefully selected to perform at a maxiumum level, and at all times. The tubes are quality selected, precision matched, and burnt-in for 24 hours after mounting in the amp to reveal any quality issues in time.

The EBS Classic T90 has a separate input for Active and Passive instruments and a separate output for 4 Ohm, and 8 Ohm speaker cabinets. The control panel has a classically styled layout with controls for Volume, Treble, Bass, and Presence. The balanced output is tube driven, using a separate ECC83 tube, only for the XLR-out.
