The Maza FX First Line Screamer is an analog overdrive pedal from the Argentine maker Maza FX. The maker describes it as "An overdrive that goes beyond the classic, with more gain, more clarity and a more defined sound," placing it in the family of Tube Screamer style drives but with a fuller voice. according to RockBoard's PedalPedia, it is "Perfect for emphasising your solos and refining your riffs, offering versatility and a fuller tone every time you play."1
If you are new to overdrive as an effect type, it pushes an amp or models an amp pushing itself: light versions add grit and touch sensitivity, heavier settings work as a lead boost. The First Line Screamer sits in that family, and you can compare it with other circuits on the Overdrive Pedals page or in the Boss SD-1 vs Ibanez TS9 Tube Screamer comparison.
Power and practical use
The pedal runs on a standard 9V DC supply with center negative polarity, the same arrangement as nearly every compact pedal, and it draws 10mA. That is a light draw, so it fits alongside other pedals on a daisy chain or a small isolated supply without trouble.1
Maza FX publishes an English manual for the First Line Screamer as a PDF on its own site, which covers the controls in detail.1
Where it sits in the Maza FX range
The First Line Screamer is part of Maza FX's First Line series. The series also includes the Maza FX First Line Fuzz, a fuzz pedal that shares the same power arrangement of 9V DC center negative.2 For a higher gain drive from the same maker, the Maza FX Mr D ODS is also covered on this site, and the Distortion Pedals and Fuzz Pedals type pages place these circuits in context.
