Mooer is a Chinese company that produces affordable, compact guitar effects pedals and other music equipment.
Established in 2010, Mooer quickly gained popularity for its “Micro-Series” pedals, which are small but deliver a wide range of effects, from overdrive and distortion to reverb, delay, and modulation. Despite their budget-friendly price, Mooer pedals are appreciated for their solid build quality, ease of use, and impressive sound.
The company also offers multi-effects units, amplifiers, and accessories, catering to both beginner and experienced musicians who seek reliable gear without breaking the bank. Mooer’s products are widely used by guitarists worldwide, particularly those who value portability and versatility in their setups.
Wah effects sweep a resonant band-pass or related filter through the frequency spectrum, creating the vowel-like movement associated with the treadle. Envelope filters move automatically in response to picking level, while fixed and sequenced filters use other control sources. Sweep range, resonance, direction, sensitivity and input loading determine whether the response is vocal, percussive, smooth or sharply synthetic.
Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
