Please note: this is not the original release of PH-1. It's the 40th anniversary reissued version. Original box missing
In 1977, phaser pedals had been around for a while, and there were a few popular competing models on the market. For the PH-1, BOSS engineers worked to create an improved design with better clarity and a deeper modulation range. In comparison to other four-stage phasers of the era, the PH-1 has a more natural and mild sound, with a richer low-end response. In addition, there’s a minimal level difference when the effect is turned on, thanks to its integrated output boost circuit. For the PH-1 reissue, the FETs for the four phase-shifting circuits have been carefully matched to make the response characteristics exactly like the original pedal. Furthermore, each individual preset resistor has been meticulously tuned by hand, replicating the same process that went into building the original PH-1.
