Boss pedal dating
BOSS released its first 3 compact foot pedals in 1977.
These were the OD-1 Over Drive, the SP-1 Spectrum (a parametric equaliser) and the PH-1 Phaser.
Ibanez reissued the narrow TS-808 as the "35th Anniversary TS-808" in 2014.
It is a very accurate reissue except they used JRC4558D chips instead of the 1458 chips.
These have a bottom plate that unscrews to change the battery like an MXR pedal, no plastic battery cover. It uses two 1458 chips which are the 1st version of the low-tech dual op-amp.
The OD-1 is, of course, an enduring classic which paved the way for the OD-2 (1985-1994) and the current OD-3 (1997-present).
The SP-1 found more favour with keyboard players than guitarists. But BOSS’s phaser offerings have grown and evolved over the years – along with the evolution of what phasers are expected to do.
In 1984 the PH-2 Super Phaser addressed the problem of “Well…
actually I think I would kinda like a setting that really sounds like a Leslie…” With twelve stages of adjustment for smoother, more ‘hi-fi’ phasing, the PH-2 offered two modes. The other was deeper, richer and more aggressive – perfect for the New Wave sounds that were popular at the time.
