NEW PEDALS from MOENMoen listened to the comments of both stage and studio players and redesigned this special guitar pedal for both stage and personal recording studio applications with even more options fordifferent musical situations! The BUFFALO AC-BA features a huge variety of control to shape the sound as well as other features simply not found in one stomp box.The new version has now added a ground lift switch which can connect or interrupt a ground loop which helps to eliminate hum in many situations. A great addition to this already around excellentbox!!First, it's a direct to amp EQ that sounds good straight to amp and has plenty of headroom and adjustment. It has Low, Mid and High EQ along with a Frequency knob for EQ contour adjustmentsshifting of these frequencies. Volume knob for total output level and an Attenuation knob which is for input signal attenuation/boost. I prefer this over some of my other drive pedals, colorsthe sound nicely with just enough 'edge" to the sound.Second, it's a headphone amp !! perfect for late night jams or when an amp is not available. The unit is self powered to receive a headphone connection ( small pin headphone in). Sounds somewhatlike the Rock It headphone amp when going through the Buffalo direct. Hook some effects in line, Delay, Reverb, Chorus, ect., it really starts to come alive. More than enough to inspire some newriffs with late night jams through headphones. Great for travel or carry-on.......Third, it's a direct box !! DI balanced output for going straight to a board or mixer or... unbalanced direct out for other 1/4 jack uses. This accepts three prong mic/instrument cable. Now youcan have your acoustic going direct to a mixer or mains without the constant EQ of in front microphones. Specifically voiced for acoustic application !ny three options can be useful as a stand alone item, but with the BUFFALO, it's all here in one. Very cool little box........ now with new Ground Lift switch to help eliminate hum !!The BUFFALO is analog which means no detail of your sound is lost. Everything at input will be delayed and returned at output as a whole.True Bypass switchingThe true bypass means that the input jack is connected directly to the output when the pedal is switched off. The sound coming in is totally unaffected by any filter or circuitry and it allows youto truly feel the effect when engaged.Metal Enclosure with Metal Stomp SwitchAll MOEN Effects Pedals are built in a metal enclosure and uses a metal stomp switch to assure you that your pedals are meant to be played . They are made to withstand harsh floor-usageenvironments and being heavy with heavy-duty rubber on the underside, it doesn’t move or slide away easily.
