The original QUEEN of BONE was one of our most popular DIY projects, and for good reason.  We took the concept of the boutique King of Tone™ dual Bluesbreaker circuit and added an added an onboard 18V charge pump for increased headroom and clarity.  Even better, the 18V charge-pump option is built in, meaning more headroom and clarity…and is still powered by a normal 9v DC (Boss Style) pedal power supply.

So how did the QUEEN of BONE 2 become even better?  Let’s see:

  • Detailed build video with helpful tips and tricks for a successful build
  • Now includes a “snap-off” 3PDT daughterboard for easiest wiring ever!
  • Onboard charge pump is always at 17V-18V
  • Internal DIP switch (which allows clipping selections) is now a 4 gang
  • Everything mounts to the PCB except the DC jack and IN/OUT jacks
  • All jacks are top mounted to save pedalboard space
  • Two choices where to install your LED
  • Easier to populate and build due to revised PCB layout

The QUEEN of BONE 2 DIY PCB board is essentially is designed to be mounted in a Hammond 1590BB size enclosure and uses a 3PDT footswitch for TRUE BYPASS on each overdrive side.   A common example is to set one side for a clean-ish boost and the other dirty; Then cascade the clean into the dirty side.  If you ever have run two overdrives back to back, this is how it works.  You can use the clean itself, the dirty itself, or both for tons of gain.   The possibilities are nearly endless with the internal DIP switch diode selection and internal presence trimmer controls.

The QUEEN of BONE 2 was designed with the DIY pedal maker in mind for the best building and playing experience possible.  Order yours today!

    Be patient on this build, as there is a lot to solder. It’s an absolutely magnificent sounding effect!
    It feels a little like the OCD. An overdrive that responses to your playing style and sounds fantastic with any setup.
    I praise Rullywow for the pedal design. It’s my favorite overdrive of all time!

  2. Nate (verified owner)

    Really great circuit, with a beautiful, well-thought out layout that couldn’t be easier to assemble.

    This is a faithful recreation of the King of Tone, but at a price that anyone can afford! Also, the customer support is fantastic!

    Just got thru building a KoT CLone using this PCB. Very well made, excellent layout. super easy instructions with great suggestions. I have a few more in my Cart 😉

    Just built the pedal. I noticed a high frequency noise when engaging the pedal. Worse on left side stomp. Seems to increase when I turn up the tone. I thought it may be a faulty film cap, but now I’m wondering if it is a electro-cap being stressed. There is no mention of the voltage rating for caps, but I suspect 16V is not enough with the 18V boost. Can you still implement a 9v jumper somewhere? Other than that I love the design and I think the tone is there!

    • rullywowr@gmail.com

      Thanks for the comment. If you are getting whine from the pedal then the IC you used for the charge pump is not audio rated. Try a TC1044SPCA or equivalent. Also, if you want 9V you should be able to just pull the charge pump IC and have it. Caps would be at least 25V as mentioned in the instructions.

    I was feeling ambitious and built this as my first full pedal build (I had a bit of soldering to PCB experience) and I could not be happier.

    After a friend and I put the QoB up against a KoT in an A/B comparison, I left feeling really chuffed. I run one side on clean boost and it’s virtually always on as part of my sound, I love it. I’m really happy with how it gently shapes/enhances my tone (on both single coils and humbuckers).

    The only thing I’m disappointed about is my measurements before I drilled in the enclosure haha. Great quality PCB, great instructions, great customer service, give this man your money.

    As a builder of many Rullywow projects I’m looking forward to getting this working. At the moment I’ve got no signal. The bypass works fine. So I started by measuring voltages. My 9V wall wart is putting out 15V. That may be one problem. But when I measure voltage where the power goes onto the board I’m reading +3.5V. I’m assuming I have a short or wrong part somewhere beyond the power inputs. Any inputs would be appreciated.

    This is a really nice sounding overdrive.
    It was fun to build. Very clever layout and with the drilling template everything came together easily.
    I did track down some NOS diodes, but not so sure how much it matters. Curiosity got the better of me I guess.
    The best tone for me is the first side set up as a clean boost going into the second side setup as an overdrive. Really nice full range overdrive sound.
    Have never tried the original King Of Tone, so have no idea how they compare.
    Can recommend this project wholeheartedly.

      Thanks Lars!

    Finally got it working. WOW! Excellent job! One of the LEDs won’t work but everything else in the pedal seems to be just fine.

      Awesome! Thanks for supporting rullywow.com, Bob!

    I have buy it and i’m doing the bom in Mouser, some recommendation for capacitors brand and voltage?

  10. Alejandro Garcia Canelo (verified owner)

    Thank you very much!!

  11. Jaime (verified owner)

    Very good sounding pedal indeed !!!! Really worth it !!!
    In fact I bought a second one that I will build for a friend !

    A couple of remarks:
    – You could maybe warn about using the led positions just above the footswitches. Depending on the led housing size, a small drilling error will bring it too close to the footswitch. I recommend to use the other position.
    – The input jacks are very close to the pcb. You cannot use large “closed” jacks. The open type are OK, although you have to rotate them until they fit.

    Two additions that I would have liked to have:
    – Switch to bypass the 18V pump. With a lower voltage, you get more of that nice IC distortion, especially in Boost mode. You can pull the IC, but that leaves you with 8V or less, since you still have the voltage drop at the pump diodes, and it is not very convenient if you want to change it on the fly.
    – Option in the drilling template and in the jack connections of the pcb to have 4 jacks, so that it can be used as 2 independent pedals. This would be very useful with pedal switchers.

    Only one drawback: no room for battery!

    Follow the instructions and go slow. The best pedal PCB I’ve ever built from. Truly a well designed pedal and the instructions/video are FANTASTIC. Well worth the $14.

    Fantastic sounding pedal. I like the sound without the charge pump for now. Just socket your ICs and charge pumps. I opted for the high-dollar “legit” diodes. It’s more money, but if I’m doing it, I wanted to do it right the first time.

  13. Dietmar (verified owner)

    Wow! The best-designed PCB by far, which I have ever held in my hands. Minimal cable connections, well thought-out arrangement for the components, clever connection of both platinum parts, circuit board contacts on both sides, great video with good tips for assembling.

    and the best thing is: The sound is incredible! I’m afraid this will be my all time favored pedal – these are two old Bluesbreaker/Guv’nor pedals in one 😉

    small improvement suggestion for the instructions: indication of the raster dimensions of the electrolyte capacitors and the size of the buttons;-)

    • ben@rullywow

      Thanks for the review! I’m really glad you are liking the PCB design and sound. Rock on!

  14. natedorka (verified owner)

    Where can I buy the components? Amazon?

  15. yupnitski77 (verified owner)

    Simply fun pedal and worth it all the way!
    I used MA856 diodes and ICL7660S. At first I had some noise issues with higher gain settings. It turned out to be a bad 7660, as usual. I also made a hole in the bottom of the enclosure for a quick access to the clipping switch.

    • ben@rullywow

      That’s a cool idea. Yes, you have to make sure you get a charge pump that is audio ready otherwise there will be whine in the circuit. Nice find on the MA856 diodes too!

  16. Nicholas Jordens (verified owner)

    This is highly recommended, it sounds just exquisite. Building was very enjoyable and quite easy I have to say thanks to the design talents of the creator. The trickiest element for me was sourcing some components, the film caps to be exact as you need them quite narrow but 50v did the trick. A big thanks to Rullywow, I’m delighted and proud of my QOB2!

    • ben@rullywow

      Thanks Nicholas! We are glad you are liking it.

  17. James (verified owner)

    I love this pedal! It was also my first pedal build and though seemed a bit overwhelming at first, between watching the video and the fantastic support from Ben I now have the pedal I use more than any other. Get it, make it, love it!

    • ben@rullywow

      Thanks for the feedback, James! Glad you are digging the sounds.

  18. David (verified owner)

    Finished my build today and it really is an amazing sounding pedal. You don’t need the $25 super rare and probably fake ma856 diodes. Fairchild FDH900 diodes sound amazing at .25 a piece at small bear. I use the left as a clean boost and the right as the overdrive. Puts my Princeton Reverb in crunchy strat heaven. Better than my Tumnus and Tubescreamer for sure. Favorite OD I have played. If you are wanting high gain distortion or heavy OD this might not be your pedal. This was actually my first pedal build (I have done some soldering here and there in the past but it was pretty ambitious I must admit for a first pedal project). Hardest part is getting all those parts ordered and sorted out once you get them. The YouTube video was super helpful. Follow it if you are new to this. Very good design that went together really well. One small suggestion for Rullywow: put a wiring diagram for the input jacks and the dc jack in the build docs. Had to google it. No biggie for a veteran problem solver like me though haha. Thanks for a really great experience!

    • rullywow

      Thanks for the feedback! Yes, the diodes are a small part of the overall sound. I suggest socketing (SIP sockets) and experimenting to find your favorites.

  19. Patrick Watson (verified owner)

    I’ve had mine finished for about a month now and have been able to play live with it a few times. It’s a great sounding pedal and the build was a lot easier than I thought it would be. I HIGHLY recommend getting a step drill bit if you don’t have your own drill press. It will save a lot of time in drilling out the holes in the enclosure. The build doc and video were both very good.
    I ended up socketing the op-amps, DC-DC, and the diodes. I really wanted to be able to experiment with different combinations for the best sound. I ended up going with the FDH900 diodes vs the BA282. The 282’s were a bit brighter, but the 900’s gave a more throaty overdrive tone. For the op-amps, I ended up using the NE5532 in CH1 and the LM833 in CH2. I added an external dpdt switch to the enclosure for the distorion diodes in CH2 and boosted the gain when it’s switched in because they have an inherent drop in level when switched in with the current design. I was going for a Kenny Wayne Shepard kind of tone and this gets really close for some hot rodded blues playing. I’ve used it with a Marshall Artist, Blackstar HT20, Peavey Classic 30 and a Fender Supersonic and it sounds great with all of them.
    I liked it so much I decided to build the Demented Compressor to go with it. The combination of the two is awesome, and the compressor sounds great on its own. Highly recommended. Thanks for doing these pcb’s! It makes the job so much easier. If you could do one of the Hudson Broadcast that would be great!

    Excellent design, documentation and video. It was a fairly straightforward build as long as you take your time!
