Another very poplar distortion pedal, this pedal has the tube-like crunchy overdrive and a bass boost that is as fat as the Pillsbury Doughboy on a King Biscuit binge.

The Harp Break pedal provides clipping distortion with a full range of clean to hard grit. As LEDs begin to conduct, they produce a soft clipping distortion that is very similar to vacuum tube distortion. The soft clip is visibly evident by the dim lighting of the LED on the face of the pedal, and as the DRIVE is increased the LED clips harder and begins to glow brighter: the brighter the LED, the harder the clip. The tone is very close to vacuum tube distortion but without the overtones produced by tubes. The tone is much better than typical solid state distortion created by transistors, but that is not all. The Harp Break features a 20dB BASS BOOST feature to add a fat bottom end to your tone. This pedal is a great tool to dirty up an otherwise clean amp and create distortion when going into a PA. When the pedal is not used to produce distortion, it can be used to fatten up your tone by providing

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. Power adapters are sold separately.

Harp Break

I am still working with it...only played live with it once...I guess more crunch.. less hearing My breathe through it...gonna try to make it work..Not really a blues player ...which the pedal has taught me..just thought distortion would be different...nothing you guys did. I am getting Harp Shield ..so maybe that will help. I may just have to do more research than I did beforehand.

Very Nice Pedal - Love Bass Boost!

I am really enjoying this pedal - it is a nice way to get overdriven amp tone without the amp (or helps break up the sound on amps at lower volume). It came quickly, was in good shape, and sounds really nice. The bass boost is a wonderful feature and really helps - playing a Low F harp with this pedal produces an amazingly dirty/gritty sound. I've found that the best way to get desired tone is to set my microphone volume to 80%, tweak "Drive/Volume" to the desired level and then slowly increasing the volume on the amp to the desired volume. I'm Looking forward to trying other Lone Wolf Pedals.
