CHARLIE MUSSLEWHITE - "Hi Randy, I sure love the new Harp Attack. I had been using the Harp Tone+ whenever I had time to be in Cyndi Lauper's band, but recently I joined her in Boston for a show and got to use the Harp Attack and it was a BIG HIT"


"Not only does Lone Wolf make great gear, but the service I have received has always been first class."

"Hi Randy, Yesterday I received my Harp Octave pedal, and I just wanted to thank you. It's my 4th Lone Wolf Blues pedal and I just cant say enough about them! I play through a '59 Bassman clone that was built specifically for harp, so my tone starts off sounding pretty damn good. I started off with the Harp Break to add a little more "chunk" to my sound (especially when playing at a lower volume) it fit the amp beautifully! (It also goes with me when I take a small Fender Pro Junior for an open mic, or very small venue) next I bought the Harp Shield. I find that I don't always need it, but it's like having feedback insurance on my harp rig. (better to have it and not need it, than not have it and need it) Then I found that a few of better jam sessions in my area didn't even have the room for a small harp amp, so I played through a friends harp attack into my H&K RedBox DI, and couldnt believe the tone! Other than losing some stage presence by not having an amp, I was really impressed. (ordered mine the very next day) I'm really diggin' my new Harp Octave, and can't wait to use it at a gig! Thanks again for the great products! I think the next one on my "need" list is one of the delays. I have been using a Delta Labs Digital delay, and while it works ok, I find the tone to be a bit "thin". P.S. i've let several guys "test drive" the pedals at different open stage events, and they're always impressed. I have also passed along your website info at gigs to a few people asking me about my gear or tone."


Born out of a love for the blues and a lifetime desire to be able to play music, I began learning blues harp. And anyone who has ever played harp knows that as a natural part of the process, you will become interested in vintage tube amps. Being an electronics tech by trade (30+ yrs exp.) and having began my electronics education by studying vacuum tube amplification in ancient times passed, I purchased some test equipment, obtained a Silvertone 1482 in disrepair, and started restoration.

I enjoyed the process so much that I began a quest to build the perfect tube amp designed specifically for blues harp. I purchased an old tube stereo chassis and built a test bed to mock-up and to test my designs. The blues harp player is unique in that he typically uses a microphone connected to a guitar amp that has too much gain for a mic, which causes feedback issues, and if that isn't bad enough the frequency response is too high. I have worked extensively to engineer a preamp that overcomes these problems and to match it to a final stage, giving the harp player the tone and range in distortion that they love.

Returning to my roots in electronics has been very rewarding. Over the last few years I have re-educated myself in the world of vacuum tubes, reading tons of technical material and designing amps as well as filtering out fact from myth. For those interested, the technical writings of Norman Crowhurst are about the best you can find, filled with facts and explanations in common sense audio amp design.

Looking for a new project and having read all of the complaints that harp players have about using guitar delay pedals, I decided to build a delay pedal designed for harp. I did my due diligence, as they say, and created the HARP DELAY®. I mentioned the delay on a forum, where Ryan Hartt expressed interest. I sent Ryan the delay, and he loved it. I then decided to try building a few and offering them to the harp community. Before I know what happened I was running a part time business in my shop.

Next came amplifiers, designing and marketing an amplifier nagged at me for a long time, I fealt this was something I could and should do. I wanted the amp to be a working man's amp, an amp the looked good had a boat load of tone and was affordable. There are enough boutique amps on the market and I wanted to provide amps that sounded just as good but didn't break the bank and I think we accomplished this task with the Harp Train line of amplifiers.

We have since outgrown my shop at home and have relocated to a nice building that houses the LWBC pedal business and Pedal Parts Plus, a business that supplies finished enclosures to boutique guitar effect pedal builders. We have 7 employees and my part time business is now a full time passion.

I want to offer thanks and recognition to all of the great people on the internet who share their work and knowledge regarding blues harp and tube amplification in general. There are links throughout this website to some of the great sites whose resourses I found helpful. I also acknowledge and thank Nathan Heck, who has worked with me since the beginning; Nathan, I could not have come this far without you, thank you.
