Independent shopping perspective
The Korena take
The 90s Triple Rectifier is a 150W, two-channel tube head powered by six 6L6 tubes. Each channel has its own full control set, with Orange and Red Rectifier voicings at the core of its high-gain design. Selectable tube or silicon-diode rectification and the Bold/Spongy power switch let the player alter the power-section response. A tube-driven series loop, external switching connections, and multiple speaker outputs make it ready to sit at the center of a larger guitar rig.
Strong match
Who this is for
- High-gain guitar rigs using palm-muted parts, detuned riffing, and dense live or recorded arrangements.
