6 Phi 4
Vahlbruch FxProduct Description
The 6-PHI-4 pedal is an analog JFET phaser designed to deliver classic phaser tones with enhanced clarity and depth. It features 4 or 6 vintage transistors, allowing you to easily access rich 4-stage phaser sounds, as well as a unique 6-stage mode that adds warmth and fullness, reminiscent of univibe and Leslie effects.
This pedal provides deep and consistent modulation with minimal background noise, thanks to the careful selection of NOS transistors. The 6-PHI-4 also offers extensive tonal shaping options, with 'Speed' and 'Intensity' controls for a wide range of phasing effects, along with a 'Volume' control for output adjustment. An LED indicator displays the modulation rate for precision performance.
