Stylon Pilson Posted November 18, 2015 Share Posted November 18, 2015 I recently bought a pedal second-hand (Mooer Sweeper) and I've noticed that when I step on the button to switch it on or off, it sends a fairly loud pop through to the amp. Would this be a consequence of a faulty unit, or poor design? S.P. Quote Link to comment Share on other sites More sharing options...
Nessy Posted November 22, 2015 Share Posted November 22, 2015 True bypass pedals (like the Mooer) are sometimes susceptible to audible pops. It happens when an audio signal is suddenly switched to a different DC voltage, and putting said audio signal through hard contact mechanical switches (like the Mooer uses, the 3PDT) also contributes. Because of this many TB pedals pop. However I also have a second hand Mooer Bass Sweeper, and it seems to pop excessively loudly compared to other TB effects - I never investigated it any further, so I'd suggest your pedal isn't a one-off.

Guest FretNoMore Posted November 23, 2015 Share Posted November 23, 2015 Sometimes you can modify the pedal and add what's called a pull down resistor to remove or minimize the pop. Quote Link to comment Share on other sites More sharing options...
Sibob Posted November 27, 2015 Share Posted November 27, 2015 Try putting a buffered pedal in front of it, can help reduce it. Why it's often good to put your Boss tuner first in line Si Quote Link to comment Share on other sites More sharing options...
