Boss
BOSS began in Osaka in 1973 as MEG Electronics, a company dedicated to effects. Its first BOSS-branded effect was the CE-1 Chorus Ensemble in 1976; the OD-1, SP-1 and PH-1 launched the compact-effects series in 1977. The JustPedals catalogue includes familiar overdrives and distortions such as the OD-3, SD-1, BD-2, DS-1 and MT-2 Metal Zone, as well as utility items such as the PCS-20A cable. BOSS now spans compact pedals, multi-effects, loopers, tuners and controllers. Manufacturing origin should be checked by model rather than inferred from the brand’s Japanese history.

EQ Pedals
Equalisation changes the level of selected frequency regions without intentionally adding modulation or time-based effects. Graphic EQ divides the spectrum into fixed bands, parametric EQ allows frequency and bandwidth to move, and simpler designs provide broad bass, middle and treble shaping. Available boost or cut, centre frequencies, filter width and overall output level determine whether the pedal makes corrective, tonal or gain-driving changes.
