THE LONE WOLF HARP TONE+®
ABOUT
The Lone Wolf Harp Tone+ is the answer for those who want a bassier tone, a fat bottom, more depth, for those
who want to keep their vintage amp original and unmodded, those who are tired of trying all of the different
combinations of tube brands and types and those who are tired of chasing that silver bullet mod that promises to
make their amp a great harp amp. The Harp Tone+ really stands out with tongue blockers, chording and train
rhythms, higher keyed harps suddenly have depth you have never heard before.
The Harp Tone+ is designed to make any amp a good harp amp by addressing
the shortcomings of the guitar amplifier itself, the coupling caps, the excessive preamp gain and speakers that do
not have a good bass response. The pedal is essentially a 2-band equalizer with a range of 20db in gain to a reduction
of 20db in level for both bass and treble frequencies. With the
controls in the position shown below your tone and level are unchanged and from this point you can increase or
decrease your bass and treble frequencies as well as lower your volume to control feedback or increase your
volume if you want a little gain for solo's. The Harp Tone+ does not eliminate feedback but it does help control it and
it has a true bypass.
Why 20db in gain? The 20db in gain for bass frequencies is necessary because they are so low in comparison to
the mids and the highs that are produced in harps, they are there but they are at a very low level. This pedal is
ideal for increasing bass frequencies in you tone, it is ideal for amps with no tone control, increasing volume for solo's,
for decreasing feedback and for giving the harp player more control over his tone when playing into a PA
The Harp Tone+ makes any guitar amp a good harp amp. How? By providing the gain necessary to drive bass
frequencies through the low value coupling capacitors for one; and if feedback is a problem and the amp starts to
feedback too early due to the excessive preamp gain found in all guitar amps then by lowering the volume on the Tone+
you can counter that excessive gain and now turn the amps volume up to a much higher level where the volume control
setting will not be as critical in relation to feedback. Plus, if you have a speaker that is poor on bass response you will
now be able to push it harder with higher-level bass frequencies and bring it to life.
How does the Harp Tone+ make any mic a better mic? The ultra high input impedance, the gain available in the bass
frequency range and the volume control that helps control feedback or add volume whichever your needs are.
SETTINGS
Set the volume on your amp to around 8 and then turn back (ccw) the volume control on the Tone+ until feedback stops;
then, set the bass and treble to your preferance and fine tune your volume with the volume control on your amp.
This method will supress feedback and allow you to get more volume from your current amp.
POWER
To make it all just a little easier Lone Wolf is offering a power supply for US and EURO customers to power
your Harp Tone+. 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.
Stephen Schneider demo'ing the HARP TONE+ - The amp is an Epiphone Valve Jr. that's stock except for a Sovtek 5751 preamp tube; I'm using a Superlux mic thru a Lone Wolf Tone+ pedal--the entire rig inc. cables is under $500 retail. The Tone+ has bass about 3 o'clock, Treble about noon, and its output level is clicked up one notch over flat. I'm playing a self-customized Bb Lee Oskar with Hering Black Blues covers that's in 7-limit JI tuning.

While at the International Blues Challenge Ian used the same amp for guitar and harp, he would unplug the cable from his guitar, plug it into his mic, hit the swtich on the Tone+ and instantly had great tone without feedback trouble.

Fender Blues Junior and the Harp Tone+
Bottom line is that you can get a good harp tone from a Blues Jr with the Harp Tone+.
First thing harp players need to do is change out the preamp tubes with
V1-V3 as 12AY7, 12AX7, and a 12AX7 phase inverter, using quality tubes. I tried the
BJ/HT+ combo with the mic I usually play out with, a “Harmonica Honker”
and a Shure 57 Beta. In both cases the sound was good to very good but I would
have liked a stronger presence in what I think is the 3 to 4 Khz range. Here are the suggested
settings for BJ/HT+ combo: BJ Master @#10 (not 10 o’clock), Middle 2-5, Bass7-10,
Treble 10-12, Volume 5-8. The HT+ settings are ( “o’clock.) Bass 2-3 o’clock,
Treble 4-5 o’clock, Volume noon to 3 o’clock. This produced good to very good tone.
As a dynamic mic player, I want a wider pallate so I don’t want the Bass
to cut the treble per se, I am happier when they are more independent.
Peavey Transtube Series SS Amp and the Harp Tone+
You get very good to awesome results, especially if loaded with smooth,
non-ribbed, early breakup speakers.
Then the amp just screams (WOW!). You can get that oft wished for
“monster tone”. I love it.
REVIEWS
Hi Randy,
Just wanted to let you know that i've tried the tone + at a few gigs
and I think it is fantastic, it has fattened my tone, reduced
feedback and given me a lot more volume, it's easy to use too.
thanks,
Ian

Hi !
I have tested the Harp Tone+ a week now and my first impression is that it is a nice add
to my epiphone valve junior head. It really added the lacking bass response in the amp,
and i liked how it sounded. I have tried different eq pedals for guitar and bass and also have
a mid bass cut from Kinder musical instrument which add some bass response to it.
But the pedals above only add 12-15 db on the lower end freq and also only add 50hz on the
bass eq. In my mind there was always something missing there when i played.
The Harp Tone+ is the best i have tried so far and a cheap alternative to make my cheap
amp sound bigger.
Thanks !
Regards, Peter
Hi Randy
I used the new tone + this weekend on 2 gigs and it does everything you said it would.
My old Univox amp has no bass/ treb controls so the pedal really added the bass I was missing.
The Tone + has a new permanent home on my pedal board.
Thank You

Hi Randy!
Hope all is well, just wanted you to know that I've been using the Tone+ pedal for a while now and this is my opinion about it.
1. Easy to use just three knobs and they kind of speak for themselves
2. Built like a tank I expect it to last a lifetime
3. I have placed it early in my signal chain which seems to be the best spot for it.
4. It delivers what you say about it on your site and fattens up your sound depending on mic and actual harp key. I tend to use it more
with my higher harps But works good on lower keys to. When playing with my Harp Commander straight in to the PA my cleaner mic's
tends to shine more compared to bullet style mic's. On the other hand this doesn't bother me too much because I rarely use anything
else but my stick mic's (EV 660, Shure 545, 585 or the Fireball) I don't have anything against bullet style mic's but they seems to be
very one dimensional. Yes you get a great fat Chicago sound out of them but tha’ts all!
5. I like this Tone+ pedal a lot I used to have an MXR ten band eq but this pedal does the same work whit out the hassel that you
have to put down every time you use the MXR, ten different sliders to mess with is just to much. After all I'm a harp player not a
sound scientest.
Great work Randy and thanks a bunch!
The Harp Tone+ just arrived - wanted to let you know and in first 5 minutes - WOW - exactly what I was hoping for.
Just wanted to also let you know that when the volume switch is turned, there is some static during the adjustment
but once set it's not a problem - man that is a mellow tone!!! Thank you, thank you, thank you. I can hardly wait to
give it a full work out.

Hi Randy !
The new version of the Harp Tone+ (the version with the volume control) arrived a couple of days ago. I thought it was
good before but must admit that it is even better now. The adds with volume control and increased gain must be that +
after the name Harp Tone ! Even if most amps have a bass control on them, they don’t deliver the bass you want.
If I should describe it better: My amp also have a body now, not only a head ! Thank you very much !
Regards, Peter
Harp Tone + : It is very dangerous to promise so big thing , that You do with Tone+ - but every word was worth of it.
Harp Tone+ is fantastic when play with little amp. No more mod. to change loudspeaker elements - just play through
Tone+ - and You have those missing bottoms. And what a dynamic - unbelievable "rumble" - in positive sense. A giant
of the low sound. Great
