harp octave pedal



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 adds no solid state distortion; but what it does add are octave-up overtones that manifest itself in the mid-range with a rasp that brings out whatever distortion is going on with the amp. The end result is a raspy/crunchy distortion that can be mild or intense, according to the settings chosen. This pedal is best when using the pucker, lip block, and tongue block techniques. 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 reduce 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 from 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. 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. The Harp Octave offers all of this and a money-back guarantee if you are not satisfied for any reason.

The 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 your output level, which does have a small amount of gain for increasing the volume when desired. A 10 to 11 o'clock setting is great for a vintage amp distortion sound.

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. Lone Wolf offers power adapters for US and EURO customers and is sold separately.

The following samples were produced by Stephen Schneider for our forum members, and he graciously offered them for use here:
Sample 1    Sample 2    Sample 3    Sample 4    Sample 5   

These samples were produced by Steve Marriner, frontman for MonkeyJunk, using a '60s Astatic JT-30 with crystal element and a 1960 Fender Concert Amp:
S Marriner 1    AB test, Steve starts with the Harp Octave OFF and about half way he turns it ON.
S Marriner 2    Steve ripping it up with the Harp Octave.
S Marriner 3    Steve combining the Harp Octave and the Harp V2 Delay.



REVIEWS Stephen Schneider field tested the Harp Octave and reported the following:
"Stuff I love: The presence and clarity of the harp seems enhanced without inducing more feedback right away. I A/Bed with the Jayphat to be fair and at what I thought were similar levels, the Octave just comes across more clearly. Hard to explain, I think it's additional harmonic content. Great 'uncup' sound with the crystal mics too, that's a new one for me. It's not hard to elicit the overtone on the 'Juke' riff on the original recording and beyond that, the Octave sound at lower settings really evokes the 'old amp' tone somehow, heightens whatever old-school rasp & distortion & breakup are happening, at least with the H410. The sound of a sustained four- or five-hole draw chord on a 7-limit JI harp that's in tune is UNBELIEVABLE--not that it can be used easily in a song, but for an opening or ending cadenza, it absolutely expands to fill the room. I've never heard a sound like it, especially up on a D harp. A related thing is that I think the Octave locks in very well with 7-limit JI the difference tones' octaves also come in and the sound expands some more. Really sweet and deep and in combination with the distortion factor, I really think the Octave might be right in the pocket for old-school blues harp diehards. Incidentally, I tried the hardwired Kobetone/recent Bluesblaster crap crystal thru the Octave last thing and it came out pretty tolerable, needed more meat but the Tone+ can probably add that if really necessary.

Single negative: Too much effect and I can make it cut out/clip with hard TB attacks, especially on the low end of low-key harps. That is OK because it may only be happening when the effect is set higher than anything I would probably use. Also, I seem to be able to make many digital devices react that way (Tone+ doesn't do it tho) and it may be mic diaphragm distortion involved."

"I'm really impressed, it fattened up the tone and I can't believe how it cuts the feedback. I got way more volume and a fat slightly overdriven sound. Wow!"

Mats Rosen writes:
"I must say you make awesome pedals, I have the Octave pedal now and use it with my Bassman. The Bassman without pedals is a great amp loud and lot of punch. With the Octave pedal it is a killer, much, much, more bottom, crunchy and absolutely AWESOME. And best of all I can stand just a couple of feet from the amp without any feedback problem."
-Best reg, Mats

"I received my Harp Octave pedal on wed. Of course I had to try it out in my basement studio right away. It did exactly as Randy said it would, adding tone to the midrange. The big test was on sunday when I used at a local jam. With the Blend set on 12:00 and the volume at 2:00, my Sonny Jr. Avenger amp. had a whole new attitude. It would seem that the effects unit made it possible for the 45 watts of the amp to be put to work. The difference was quite noticeable to others who had heard my amp previously. I just love it."
-Thanks, Andre

"Hi Randy, Got my Harp Octave this friday and gigged with it on Saturday. The Harp Octave is a great little box, it allows my big Fender Bassman to sound just like a small champ but with a BIG tone, just like I want it to sound. The Harp Octave is worth every dollar."
-Best Regards from a satisfied customer

"Tried the new Octave pedal at a gig Saturday, and it worked great. So far my main use for it is with some of the higher pitch harps, i.e D , etc, seems to give them some 'grit' and 'meaness' as well as a little boost in room penetration."
-Thanks for a great product, Tim G
