The Black Howler is one of those pedals that you don't quite know what to do with until you actually sit down and play with it. It's a swell pedal of a slightly different variety.
Most swell pedals on the market are either auto swells or manual pedal volume controls. The Black Howler is somewhere inbetween. Lets see if I can explain. The Howler has 2 knobs, the first of which sets the volume you want to start at. The lower the volume you start at the bigger the swell. The second knob controls how long it takes the swell to reach its apex. From a range of 0 to about 10 seconds. The stomp switch is actually a momentary switch that as long as you are pressing it the swell is activated. When you let off the switch the swell immediately returns to its starting volume. Well now your probably saying "well I can do the same thing with the volume knob on my guitar", and it's true you can. The big difference though is when you set up the Black Howler the way you want it it will repeat those setting of intensity and time delay exactly every single time you hold the switch down. It's probably not the kind of pedal your used to, and that makes it perfect for experimenters of all genres. And since we named it the Black Howler we decided to leave the writing off and keep it a black on black on black design.
