The Harp Reverb produces a very high quality spring reverb effect, it is engineered for harmonica players and is unique in that the reverberation is tone adjustable while leaving the original notes unchanged. You will add a great spring reverb effect to your music without loss of tone or added feedback issues. What is a reverb effect? A reverb effect is a combination of the dry signal, which is the note that is being played and the effect which is an image of the same note repeating multiple times close enough together so that they sound merged as they fade away. Think of the repeating “boing” sound a spring makes when plucked with your finger. The sound of reverberation is prevalent in large empty halls and this is exactly what the Harp Reverb emulates. The reverb effect is great for harp because it adds a whole new dimension to the sound, giving it the depth that is lacking and making the harp sound like a much bigger instrument. There is however; a negative aspect to reverbs, they do not have a flat frequency response. Low frequencies are lost in the reverberation and when you combine this with the fact the harmonica is a tinny sounding instrument, the result although still positive is less than ideal. This problem is resolved in the Harp Reverb with the addition of an active tone control that is placed in the effect circuit. So now, you can adjust the tone of the reverberation to make it bassier, giving it more depth and fullness, while leaving your dry signal (the note you played) unchanged.
There are two controls, the Reverb and the Spring Tone. The Reverb control is in effect a blend control that adjusts the level of the reverberation making it louder or softer. The Spring Tone control is an active tone control that sets the tone of the effect signal while leaving the tone of the dry signal unchanged. The bypass switch is a true bypass that allows the user to put the effect in and out of the chain as desired.
The Harp Reverb operates off of a 9V battery or a 9V DC power adapter (Power supply sold separately). The DC adapter requirements are a 9V DC with a minimum 100mA output and a 2.1mm x 5.5mm connector with a negative center surrounded by a positive outside. The battery is switched OFF when an external power supply is used, and the unit is always powered whenever the mic is plugged in.
