THE LONE WOLF HARP ATTACK®
ABOUT THE HARP ATTACK
The HARP ATTACK is designed to provide true power tube distortion in a pedal. This pedal
is not your typical tube preamp that uses a triode; this tube uses a subminiature beam power
tube, the same type tube as a 6V6 to provide the tone of an overdriven single ended amp. It
produces a fat punchy tone that can be set with the exact amount of overdrive desired. You
can certainly tell there is a tube inside of this pedal. The pedal is designed with a high impedence
input buffer providing 10M ohms of resistance to get the best tone from your crystal, CM
or other high impedence microphone. A DRIVE control sets the amount of power tube saturation
desired, a trebble cut TONE control trims unwanted highs and an output VOLUME control
sets the output level. The output of the pedal is also buffered with an FET amp that adds
extra gain to extend the life of the tube, this gain is controled with the pedal volume control.
The NOS subminiature tube is slightly microphonic but it goes away shortly after turning the
pedal on, it is not noticable in a live situation and the pedal has to be knocked to be effected.
The footswitch is high quality and makes a metallic click when pressed, this also can cause the
microphonic tone so it is adviced to leave the pedal on while performing. It is not designed to be
a distortion effect to be put in and out of bypass while performing, rather, a tube effect pedal to be
set up and left in service while performing.
The Lone Wolf Harp Attack fills several needs of harp players; by providing true power tube
overdrive distortion in a pedal it allows you to plug straight into a pa and get an overdriven 6V6
sound or dirty up an amp that is otherwise too clean. The Harp Attack gives an excellent tube
sound to a solid state amp and it makes a great easy to bring along back-up harp amp. The
pedal does not produce massive distortion but a smooth overdriven tone. Put it in your harp case and take
it to jams or use it in line with other pedals to develop your own signature tone. I recommend
that you install this pedal last in line with other pedals, but this is only a recommendation.
POWER
The delay operates with two 9 volt batteries or an 18vdc power adapter. 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 mic input jacks acts as the on-off switch.
Battery life is estimated at 15 hours of playing time.

REVIEWS
Steven Schneider who field tested a prototype found the following.
"With a Superlux mic the Harp Attack felt and sounded like playing a 6V6 amp with a fairly
stiff preamp providing a punchy response. Too much drive was like pushing a 6V6 amp too
hard but backing down form that yeilded a nice pocket that wasn't hard to find. It was quite
responsive and expressive, one can tell there is a tube in there. Really honkin' bottom end
available with a rich full sound that is typical of Randy's work. The Harp Attack is much like
plugging into a good harp amp, the bass and mids are appealing, responsive and projected.
The highs are clear and balanced, you can work the whole harp evenly but the lower bends
work like a tube amp and even though there is a sharply defined note envelope it give the
impression of a warm fat tone."
Steven reported several successful outings useing PA's at jams and found consistantly good
results and that the pedal was easy to set up.
David Krauss of The Blues Drivers also tested a protoype and reported.
OK, you are right; this thing does what it is advertised to do. When I was first testing this pedal
for you I found the Harp Attack to be not different enough from other "overdrive" pedals to
matter much to harp players. However, after messing around with this thing for a couple of weeks
I'm changing my story, I love it. Works great to dial in the right amount of grit to my bullets, my
Beta 57 (very clean mic) and my Harmonica Honker. It can seriously transform both my Peavey
Transtube 40 watt and my Blues Junior. I suggest that when folks get it, they set the amp/pa to
their taste, set the Harp Attack controls at noon and then go from there to tweak tone, drive
(break up), and volume. The Harp attack is small; it works, and does what you say it will do.
It’s kind of like Champ in a pedal. Very cool. Nicely done, Randy.
The Harp Attack does what you want it to do; give a real convincing tube overdrive sound through
a SS amp or PA. On my Cube 60 (with the stock 12' speaker) it worked better with my bullet than
my Beta and in both cases tweaking the HA tone knob has the ability to suppress the irritating high
end harshness and really adds convincing overdrive with round brown break-up in both JC clean
and the Fender Blackface settings. Every player will have to tinker to his or her liking, but the bottom
line is that the box can deliver the goods. I use a Harmonica Honker mic on about 95% of my playing
and the Beta on the rest of my playing so you know that I am not a diehard Chicago player per se,
but I am a tone freak and I think you have another honest product directed to the needs of a variety
harp players. I continue to use your delay on every gig and am putting a jam rig together with the
Peavey and the Tone +.

My Harp Attack pedal arrived today, (kudos to USPS - 3 days from Louisiana to Nor Cal !), and it is
all you promised and more. I can get as much overdrive as I want at any volume from living room to
dimed out and the increase in presence is phenomenal. In combination with the LoneWolf Delay I'm
getting a HUGE sound from my 18 watt HarpGear - I'm a happy harp player! Thanks for producing
such a great tool in the endless search for "the Tone".

I received the Harp Attack today, Played it through my Fender Bronco, the first year that Leo offered solid state.
I'm blown away with the sound!!! Thurs night I'm playing outside at Island Blues in St John, and can't wait to plug
it into a powerful PA. Thanks so much for everything. I think you saved me $2000 by not having to buy and tote
around an Amplifier.

Hi Randy,
Someone just posted this video of us at a festival we played at last month, we flew there so I used the back-line fender twin provided by the festival. I had about 5 minutes to set up because of the tight change over times between bands and used the Tone +, Harp attack and Lone wolf Delay. The pedals provided a huge improvement over the sound I got through that amp without the pedals, I just thought I'd share it with you.
From Zack
Randy I got the pedal! This thing sounds INCREDIBLE. It makes my amp sound SO distorted, which is what I've been trying to go for with no luck and through the PA? WOW.
