The pedal that established Lone Wolf Blues Co, sure there are cheaper delays but there are none that are better. The Harp Delay is the first and still the only delay pedal designed for harp players, try it and you too will be a believer.

To my 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 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 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 provides the effect of a distancing echo by reducing the highs more on every repeat. This delay has an even better roll-off in high frequencies than the Boss analog delay. The delay operates off of a 9 volt battery or a 9V DC power supply, and it has reverse polarity protection. The battery is switched OFF when an external power supply is used. The LED is ON when the delay is in, and is OFF when the delay is in bypass. The mic "IN" jack acts as the ON/OFF switch, and the bypass is a true bypass. The Harp Delay is guaranteed to please even the most diehard analog delay fan.

The settings are very basic. For a reverb type effect, set the DELAY at 10:00, REPEATS at 3:00, and BLEND from 10:00 to 4:00. To acheive a slap-back, set the DELAY from 9:00 to 5:00, REPEATS at 7:00, and BLEND from 10:00 to 4:00. To achieve an echo effect, set the DELAY from 8:00 to 5:00, REPEATS from 9:00 to 5:00, and BLEND from 10:00 to 4:00. This will get you started, but ultimately whatever setting you like is the right setting.

The pedal can be powered with a 9V battery or a DC adapter. The DC 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.

As advertised

I tried purchasing the Delay V2 since I have 2 pedal boards and have this model already on one. Thought I’d give it a try. Since it was out of stock I bought another Harp Delay and wasn’t disappointed or surprised with it’s quality and sound. Thanks
