The Harp Octave is a great tool for the harp player who wants to have diverse sounds. It is a clean octave up generator in the sense that it has adds no solid state distortion; but what it does add are octave-up overtones that manifests itself in the midrange with a rasp that brings out whatever distortion is going on with the amp. The end result is a fuzz-crunchy-distortion that can be mild or intense, according to the settings chosen. This pedal is best when using the pucker, lip block and toungue block technique. If you've ever wanted your big amp to sound like a nasty little vintage Champ or Princeton, this is the pedal that'll do it. The effect will really cut through the mix and reduces feedback, you will get more volume out of your amp before feedback than ever before. The Harp Octave has a buffered input, true bypass, a Blend control and a Volume control. The Blend control increases or decreases the level of the generated octave and the Volume control allows you to have more control over your volume for solos and when playing into a pa. The buffered input provides the high impedance termination necessary to get the best tone form crystal, cm and cr elements; the output is also high impedance and plugs straight into your amp. The battery is switched off when an external power supply is used and the LED is on when the effect is in and is off when the effect is in bypass. The IN jack serves as the on/off switch so the pedal cannot be accidentally turned on and run your battery down. Plus; unlike guitar pedals, there is no loss of tone through the Harp Octave. The Harp Octave offers all of this and a money back guaranty if you are not satisfied for any reason.
Settings are very basic; when the Blend control is fully counterclockwise only the dry signal is heard and as you turn the control clockwise the octave will increase in level until it is at the same level as the dry signal. The Volume control sets you output level which does have a small amount of gain for increasing the your volume when desired. A 10 to 11 o'clock setting is great for a vintage amp distortion sound.
To make it all just a little easier Lone Wolf is offering a power supply for US and EURO customers to power your Harp Octave. The ac adapter requirements are 9V DC with a minimum 200mA output and a 2.1mm x 5.5mm connector with a negative center and the outer positive.
