Orange Introduces 4 Stroke Bass Amplifiers
Orange Amplification has introduced the 4 Stroke Bass Amplifier, an all-analog bass head available in 300 and 500-watt versions. The Class AB amps are described as staying “crystal clean and expressive all the way up, without ever becoming sterile or fatiguing.”

Each amp centers around a 4-band parametric EQ section that has variable frequency knobs for Bass, Lo-Mids, Hi-Mids, and Treble ranges. Their corresponding knobs level knobs allow for boosting or cutting each frequency up to 18db. The signal then heads to a footswitch-able Class A compression circuit.
“Rather than a common hard limiter, the 4 Stroke’s Class A compressor design maintains the transients of the input signal for a dynamic playing response,” the company writes. “The carefully developed sidechain has a fattening effect on the core tone at lower compression settings, whilst increasing the amount of compression adds a springy character to the attack, great for heavy thumb work.”
Other features include a pair of Speakon outputs plus balanced and line level outputs. The Orange Amplfication 4 Stroke Bass Amplifier will be available soon with to-be-announced price points.
