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. The power adapter is sold separately.

Reverb for my vintage amp

The reverb pedal is a perfect fit for my vintage amp.I especially like the spring tone control.It works as a tonal adjustment + it also changes the tone of the amp somewhat.So two for the price of one...

Product still hasn't arrived !!

Hi guys , Product has not arrived .Tracking says it only left Taiwan on 26th ,and lord knows how many more short flights /airports etc it's going to have to go through before it finally lands in NZ and eventually to me . As you can imagine I'm getting pretty frustrated with this rather long delivery process. Anyway , will keep waiting in hopeful anticipation . Cheers , Ross MacKenzie

I don't have a lot of experience with reverb pedals. What is the difference in the 2 knob settings. How should it be set for best results!

Love it!

I really like this pedal so far. I have changed my approach from using just the LW Delay to using the Harp Reverb plus a cleaner delay pedal to get the best of both worlds. Lots of fun playing with this pedal, and you can really twist the knobs and do no wrong to your tone, just about dialing in how much you want. Two thumbs from me!!
