The Rare is on the lower right of the pedalboard. Pettyjohn stuffs everything into a polished aluminum casing with those cool maroon Davies knobs like the original, but the pedal is shaped like a typical stomp box with top mounted jacks, making it easier to find room for it on a pedalboard.

I'm starting with part of my post from another thread to save some typing time. About Pettyjohn gear:

If you open up one of their pedals and compare it to the typical pedal, even very good pedals, it's an eye-opener - no wonder they sound so good. Building pedals like studio gear is their thing, which makes the pedals expensive, but you know my system: If I can spend more to get what I want, I'm gonna spend more because cheap thrills! 😂

Basically, the Rare is Pettyjohn's idea of a hot-rodded Klon, with more headroom and a bit different tonality, but still in that ballpark. For example, they use 4 of the NOS germanium D9E diodes the Klon used, instead of two; it converts 9V to 18V operation; it has NOS Allen-Bradley resistors; an optional Emerson cap; four controls instead of 3, and some internal parts upgrades to populate the circuit boards more like studio gear.

It's not supposed to mimic a Klon. It's more an 'inspired by Klon' thing. PRS had a similar concept with the Horsemeat, and that's different from both the Klon and Rare as well.

I've run it with all 4 amps on their 'clean to edge of breakup' settings, which is normally where I'd run an actual Klon. I have it as the first pedal following the buffer in the PJ Lift.

Because I'm used to using a Klon at a very low gain setting but with a touch of boost, that's how I set this one up, though I did experiment with all of the controls, level, gain, bass, treble.

The Emerson cap was an option, and PJ says it opens up the high end. I'd say, yes, there's plenty of 'top' with this pedal and it sounds very transparent, snappy and articulate. Unlike my usual pedal setup, I rolled a little high frequency down just a touch, and added a small amount of bass, but those controls are guitar and amp-dependent (see photo above for control settings with the Fillmore). I wound up setting them one way for the Mesas, and differently for the DG30 and HXDA.

The HXDA, being a Plexi, doesn't need a boost or gain pedal. Not that it doesn't sound good, but the extra amount of gain I can get just with the volume knob on the guitar gives me all I need with that amp, so it's unnecessary.

I love it with Mesa's Lone Star and Fillmore. Unusual for me - there's only one other dirt/low gain pedal I really like with those amps: Pettyjohn's Edge (that will go back on the board once I get the correct cable to put it where I want it (I haven't decided that part yet). It also sounds excellent with the DG30, with the controls at slightly different settings from the Mesas, as you'd expect.

While the aluminum case is brushed and polished, it isn't anodized like the aluminum Suhr pedals on the board, so it could scratch more easily. I'm usually pretty careful and not worried about it, but mention it in case it bugs anyone. Clearly they were inspired by the silver Klon, with its cast aluminum case, at least in terms of color scheme.

Anyway, it sounds the business, works with all the amps, and even looks pretty snazzy on the pedal board where it has found a home.

[Edit] I forgot to mention that because Pettyjohn could only get a limited number of NOS parts, the pedal was part of a limited run. I ordered it at Christmas and it came yesterday.

I should add, it's pretty easy to set this pedal up for just the right amount of top end 'crisp' stuff, or a bit of grit, etc., at least with the amps I have here.

It's a bit strange when I realize that I've had the PRS CAD amps for a decade; the Fillmore is now over 5 years old. They all still look, sound and feel new. I still think of them as my 'new amps' and haven't considered replacing them. It's very unusual for me to hang onto gear this long, although that's actually what I want, gear that lasts!

I've had the 'Hammer Of The Gods' McCarty Singlecut for a decade now, too. Another thing I didn't expect.

There's quite a bit of classic (not metal) grind on tap if that's desired, but as previously mentioned, I like setting it just enough to add a light touch, and let the amps do most of the work in combination with the guitar volume control.
 
They make some ridiculously crafted stuff, and it sounds like you’d expect; ridiculously good!

I’d love to have a real-deal Centaur but reality is that’s not going to happen because I do love the sound but can’t stomach the sound of what it costs to get one! I have a KTR and a couple of good clones ranging from direct copy (RYRA) to same-ish execution (Tumnus) to new take on the idea (PRS). They all sound great, and can sound great together, so I don’t really even need this many of them, but I’d still love to have an original Klon. I’ve talked to Bill F. and he seems a decent guy, but I don’t ask about it. Very old news to him.

Still, I’m really glad to see PettyJohn doing pedals like these, even in limited runs, because there’s always room for doing something new, something better, or something old but better. And this one fits your pedalboard better than the bigger one they recently released!

Win-win!
 
Les, the Klon also bumps the voltage 9vdc to 18vdc internally.
I didn't know that! All the PJ pedals will take higher DC voltage in one way or another; the pedal either doubles the voltage, or you can use an 18 V power outlet with it, etc. But I didn't realize it was a Klon thing, too.
But the real question is; does it djent?
You mean like, 'Klang GuzzGuzz Kerang GuzzGuzzGuzz Klank GuzzGuzz, Kla-Dank GuzzaGuzzaGuzza?

It is highly likely that I will never know the answer to that question! 🤣

One of my friends went to an estate sale in a nearby trendy neighborhood, where a guitar playing collector's wife was selling off her dead husband's guitar stuff.

He wound up getting one of the very fat PRS Hollowbodys, lots of other stuff I don't remember, and sitting there, new in a box - unused, unopened, untouched by human hands and clearly made by Hephaestus for Jupiter - was a perfect gold Klon, with the Centaur picture.

He was ready to spend some serious coin, and the woman offered it to him a part of a package deal for extra incentive.

A few days later he brought it over to my studio.

"Let's try it out," he said.

I said, "No way. You have a very valuable, unused, gold Centaur picture Klon. It's probably worth crazy money and I'm not gonna be the guy to break the seal on that thing!"

I'd used Klons before many times, it wasn't like I'd never played one or particularly needed to. He might still have it, if you want to offer him, say, your house. 🤣

Yeah, Les, I DREAM of running into something like that one day. I know it’s just a pedal, and might not sound any better than what I already have, but it’s iconic gear… sort of like that early Boogie I bought last year. One of those things you could have bought, didn’t, and it went all Amazon-stock-price while you weren’t looking!

That’s a great story, though, and your friend was definitely in the right place at the right time!
 
I forgot to mention some other interesting stuff:

1. The switching is via electronic relay true bypass, so turning it on and off doesn't create pops or noise. Quiet switching is always desirable.

2. They just introduced a bluesbreaker style pedal. BB style pedals are great with the DG30. I'm thinkin' that one over.

Please forgive me if I'm wrong here, but you may be confusing two things. Some pedals internally up the voltage from 9-18, via a "charge pump." This is a chip that takes 9 volts and converts it to 18 volts. Other pedals can use either 9 volts or 18. (or 12 or 15). This simply means the pedal is built to handle 18 volts if you use an 18V supply, but it does nothing inside the pedal to increase the voltage.

There are many pedals out there that are built to handle 18 volts. Not many use the charge pump to take a 9V supply and internally up that to 18V inside the pedal.

Also importantly, most pedals (that I have read about) that have a charge pump can not use any supply over 9 volts or it can fry the charge pump. So while you can use 9,12,15 or 18 with any 18V compliant pedal, most if not all that have a charge pump to make 9 into 18 can not run anything over a 9V supply.

True to that.

What I found really interesting is the 21 Pedals. The Euna uses really unique power supply. It will accept any polarity, and any voltage from 7.5 up to 35vdc/vac. It will internally convert it to 24vdc (or 21vdc, I dont really remember) to what Euna is design to operate on. It's mental, as the PSU design takes 2/3th of the circuit component count.

It's a one of thing, but I thought it's cool as honorable mention

As I'm assuming you know, most charge pumps are specific... "converts 9V to 18V" or whatever. I have read about what you're talking about, and it is indeed interesting. Technically, it's not a charge pump, but more of a "variable voltage regulation system." And yes, I can imagine that it's a LOT of circuitry to put inside a pedal, even if it's largely chipped.

Conceptually, you wonder why you'd go to all that trouble, rather than just using exactly what your preferred run voltage is and using a specific supply or generic supply and pump. My first reaction to reading this was "more of an engineering exercise." I'll check those out.

Yeah sort off. You can "overclock" the charge pump with the diode/capacitor networks, so you can get 21vdc with 9vds input alright, there is a limit, though. Heat, mA consumption that is

The 21 Pedals dude is a legend in my eyes just for doing this :)

Yes, I was specifically referring to how this is not just a charge pump if it can take higher voltages than it's "operating voltage" and convert them down.

Quoting the website's product sheet about the Core series pedals:

"CORE Series Dual Rail Power

We designed the CORE Series with a dual rail doubling power supply. This design can scale from +/-7v to +/-18v, effecting the headroom, tone and feel of the pedal, achieving up to four times the headroom over standard 9v pedals. The internal supply achieves this by mirroring whatever input voltage you apply via the external power supply and we always encourage people to experiment. Requires clean power supplty of 7-18v with minimum of 100mA of current."


Also importantly, most pedals (that I have read about) that have a charge pump can not use any supply over 9 volts or it can fry the charge pump. So while you can use 9,12,15 or 18 with any 18V compliant pedal, most if not all that have a charge pump to make 9 into 18 can not run anything over a 9V supply.
See above.

Now tell me I'm wrong.

PS, I forgive you if you're wrong, no worries.
 
I didn’t say you were wrong, but that you may be confusing two different things.

After reading that again, I’m still confused on what they are claiming. They use the term “doubling” as if they are increasing the voltage. But then it says that it “mirrors” the voltage of whatever power supply you use. Are they mirroring, or doubling?

IF they are doubling any input voltages from 7-18, then they have in fact added a full voltage doubling circuit. That would be a lot of circuitry to add in a pedal. If they did, then I was wrong. I’d sure like to see inside one to see what they are actually doing.
