Harp Reverb pedal


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.

Special thanks to Barbeque Bob Maglinte for his help and recomendations in designing the Harp Reverb.

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. To make it all just a little easier Lone Wolf is offering a power supply for US and EURO customers to power your pedal. 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.

"I'm in love! I have had time to try the new Lone Wolf Harp Reverb for a while and I have tested it on gig´s and rehearsals using Lo-z & Hi-z microphones. I have used it on both channels of my bassman and tried bridging the signal, it works good in all positions. My guitarist tried it and fell in loved it also. The hi-z microphones create a longer reverb than lo-z, the guitar and when bridged. It has two control knobs, Spring Tone and Reverb. The reverb knob is a blend control, you can mix in how much reverb you want using it. The other control, the "Spring Tone" controls the warmth and spring like sound, and that's why my guitarist fell in love with it, too. The sound from this pedal is warm and real spring like. It sounds better than the built in reverb in many modern amps. If you like reverb, this is it."

"Hi Randy, I got the pedal and used it in a show sunday playing Chromatic through a front and center mic through the reverb to a sans amp para di direct box sending a line to a harpgear double trouble as a monitor and a line to the PA. All I can say is wow! I am throwing out the danelectro delay I was using. Thanks a lot!"

"Hi Missy and Randy, Hope things are going well for you folks. Just wanted to let you know how much I appreciate the Harp Reverb. It adds sooooo much to the sound/tone."

"The Harp Reverb really is an amazing device. I've been using it almost daily now for more than a year. With the two knobs I have on stage control over the reverb I'd like to add. Most of the tube amplifiers harp players typically use do not offer a reverb at all and if they do, I can say the sound of the Harp Reverb is unrivaled. Either playing through my tube amp or directly into the PA, my sound gets so big and fat now, its amazing. And the best is, I have control over it on Stage and I can change it easily to adopt my sound to the way I would like to make it sound for a specific piece of music."
-Regards, Olaf

"The Harp Reverb is just superb and just what I needed to finalize my harp pedal board. It has what many reverb pedals sometimes lack (and are much needed when it comes to amplified harp) - precision and subtlety. Excellent tone quality, no overtone pitch problems, a great low frequency presence, yet in a way that does not overshadow the dry signal. A MUST for any harp player wanting to gain control on the smoothness of his live sound (do not leave it to the mercy of the House PA's reverb.) and even better in studio. The spring feature is by far the best thing in it - I always struggled with some of my digital effects, that sound a little bit, well. digital. Now I have the harp reverb at the end of the chain, and I play with the spring level to make it a lot more vintage and cool sounding. Mostly I just leave it on, all the way up."
