The perfect slap back, the perfect echo, the perfect pedal. The Harp Delay V3 is great for blues, jazz, folk, country, classical.


This is not a tone-sucking modded guitar delay, but a tone-enhancing harp delay. In V3 we have created a versatile and unique delay. The dry portion of the signal passes through a buffered input and high-value coupling capacitors, assuring maximum bass response. The echo portion is tone adjustable, allowing for a broader range of sound, from deep warmth to a cutting tone. This is a digital delay that has all of the tone 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 echo tone control. 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 ECHO TONE only changes the tone of the echo, the dry signal is unchanged.

The pedal requires a 9vdc power adapter. The AC adapter requirements are 9vdc with a minimum 100mA output and a 2.1mm x 5.5mm connector with a negative center and positive outside.  Current draw is 57ma. Power adapter is not included. This pedal does not have the option of a 9v battery.

My New V3

I have dug the V2 delay for a number of years , yet the V3 is quite a step ahead. Richer tones galore, and the tone control is a brilliant addition. Lone Wolf does it again, and I feel i can speak for a LOT of harp players,in that we are glad you folks do what you are are doing for the harmonica players all around the world. Kim White
