To our knowledge this is the first delay designed for harp offered to the public. It is not a tone-sucking modded guitar delay, but a tone-enhancing harp delay. The dry portion of the signal passes through a buffered input and high-value coupling capacitors, assuring maximum bass response. The echo portion passes through 5 low-pass filters to provide maximum warmth. This is a digital delay that has all of the warmth of an analog delay and then some.

The Harp Delay has a broad range of effects. From the tiled bathroom Sun and Chess recordings sound to slap-back to multi repeats that fade out like a reverb, the Harp Delay does all of this without increasing risk of feedback and without weakening your tone. It is great for voice too. The Harp Delay is guaranteed to please even the most diehard analog delay fan.

If you are having a difficult time choosing between the Harp Delay and the Harp V2 Delay, then I recommend this delay, which has a customer approval rating of about 99%. The V2 Delay was created for the smaller percentage of  customers who wanted less filtering in the echo.

The circuit is centered around a chip that has a low noise rating at < -90dBV, low distortion, < 0.5% THD, 44k digital processing, and is capable of up to 300ms delay. The input is FET buffered for high impedance to provide proper loading for your favorite crystal or CM mic. The delay has a true bypass. The gain has been reduced to prevent solid state distortion and is balanced to have an overall gain of 1x so that the level is the same when bypassed. The warmth comes from the superior bass response, distortion-free performance, and the filtering, which reduces the highs more on every repeat providing the effect of a distancing echo.

The pedal can be powered with a 9V battery or a AD adapter. The AD adapter requirements are a regulated 9V DC with a minimum 100mA output and a 2.1mm x 5.5mm connector with a negative center. The battery is switched OFF when an external power adapter is used, and the “IN” jack acts as the pedal ON/OFF switch.

Because delay pedals are hard on batteries with an estimated 10 to 12 hours of playing time, it is recommended to purchase the 9V power adapter, which is sold separately.
