The Harp Reverb sounds not only like a genuine spring reverb tank, but better; thanks to the unique tone adjustable reverberation circuit. This pedal requires a power adapter that is sold separately. 

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 adding 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.

The AC adapter requirements are a 9vdc with a minimum 100mA output and a 2.1mm x 5.5mm connector with a negative center surrounded by a positive outside. This pedal does not have a battery option. Current draw is 64ma. The power adapter is sold separately.

Subtle But Good

I use this with a Pignose amp and it offers a nice sound that isn't overbearing. It seems, perfect for my current setup and I highly recommend it.

Feed back!!

I’ve used your delay pedal for four yrs. Never a problem! I’ve been trying to dial in the reverb since I got it. Different clubs, different rooms. Different amp setting ( treble or bass).different pedal setting. Standing in different positions to amp. When I get it up to working volume it feedbacks. Any suggestions????
