These days, there are lots of equipment options for the “amplified” harmonica player – custom amps, effect pedals and mics etc., with more coming out each year. But there are no devices or effects designed for acoustic harp. The only way for affecting the sound of acoustically played harmonica has been a player’s hand cupping technique.
Enter the “Harp Wah”.
On my first outing with the Harp Wah, it received a great reception. People compared it to a trumpet mute and they loved the sound. I wholeheartedly recommend the Harp Wah . It sounds great, it looks good, it provides a different sound and it doesn’t cost a lot of money.Harmonica World Magazine
Over the years there have been a few attempts – all fairly cumbersome and somewhat awkward attachments (or actual components of the harp) which did affect the sound but never really caught on with more modern diatonic players, either because of the inconvenience of having to attach something to the harp to use it or in dealing with the change in hand positions required to use them. The Harp Wah is a professional solution which solves these problems and provides the player with extreme cupping and “wah” effects.
