Crown Jewel

Boost Modules

18 Volt JFET Boost - $15

Similar to the Keeley Katana, the 18V JFET Boost module utilized the Crown Jewel’s internal charge pump and two cascaded 2N5458 JFET stages to deliver a very clean, very transparent, and very loud boost. A great boost for pushing your amp into overdrive or if you just want to be louder without changing your tone very much.

​27 Volt Boost - $15

This is a “lite” version of BYOC’s 27V Boost mini pedal. The Crown Jewel has an internal charge pump that produces 18 volts. It also produces negative 9 volts. We utilize the differential to create a whopping 27 volt power supply. This is the cleanest and most transparent boost we offer. If you don’t want your tone to change at all, and you don’t want any extra warmth or grit added…you just want to be louder….this is the boost you want.

LPB - $15

LPB stands for Linear Power Booster. It’s a very simple Silicon transistor boost. EHX probably wasn’t the first to design it, but they were the first to market it to guitar players. Great boost for pushing your amp into overdrive. Fairly gritty. Lots of low end. This module really excels at being used as a pre-gain to push the Crown Jewel’s main drive channel into high gain distortion.

Germanium Treble Booster - $25

This module is based on the Dallas Rangemaster. It features a hand selected PNP NOS Germanium transistor. Very warm and gritty. Almost a fuzz, but not quite. An on-board internal bias trimpot lets you dial it in to be a little hotter or cooler if you want. 

Electra Distortion - $15

Based on the Electra Distortion.  While you certainly could use this as a boost, it’s a great, simple, overdrive to stack with the Crown Jewel’s main drive channel, or to just use as an overdrive all on its own.

Octave Up - $15

This is an octave up module based on the Dan Armstrong Green Ringer circuit.

Hard Clipper - $15

This module is just the overdrive section from the Klon Centaur.  No tone control.  Just the Germanium diode hard clipping section of the circuit.  Internal trimmer allows you to set the maximum distortion.  Use your guitar's volume to control the amount of drive.  

Soft Clipper - $15

This module is just the overdrive section from the Tubescreamer.  No tone control.  No input or output buffers.  Just the Silicon diode soft clipping section of the circuit.  Internal trimmer allows you to set the maximum distortion.  Use your guitar's volume to control the amount of drive. 

Mimosa - $20

The Mimosa module is a compressor based on the Dan Armstrong Orange Squeezer

​Fuzz - $15

A silicon transistor fuzz module based on the Fuzz Face.  Actually, it's based on the fuzz part of the Thomas Organ Fuzz Wah, which was a modified Fuzz Face circuit.  Slightly more aggressive sounding than the typical Fuzz Face with more sustain.  Internal bias trimmer lets you dial in how gated you want it to sound.  Use your guitar's volume knob to control the amount of fuzz.

The Ultimate Drive and Boost Combo
$195
(price includes bare aluminum enclosure and LPB boost module)

​The Crown Jewel from Build Your Own Clone is the ultimate drive and boost combo. It is not a clone of anything. It is an amalgamation of the best qualities from many different circuits to create something entirely new that is capable of producing a range of overdrive and distortion tones like no other analog pedal has before.
With a parametric midrange, and 3-way Mid Q switch, the 3-band equalizer allows you to voice the drive channel in almost any way imaginable.

The hard and soft clipping switches allow you to select 9 different textures of distortion. Hard Ge (Germanium) clipping is similar to the clipping in the Klon Centaur, Maxon OD-855, and MXR Dist +. Hard Si (Silicon) clipping is similar to DOD 250, ProCo RAT, Marshall Shredmaster, Fulltone OCD*, Boss MT-2, and Boss DS-1. Soft Si clipping is similar to the Ibanez Tubescreamer, Boss SD-1, Boss OD-1, Zendrive*, Marshall Blues Breaker, King of Tone, and Timmy. There’s also Soft LED clipping or no clipping at all. And you can also use soft and hard clipping simultaneously like the Boss HM-2, DOD FX53, and other more obscure dirt pedals.

The Crown Jewel has an internal charge pump that provides 18 volts to the drive channel circuit while still using your standard 9VDC negative tip power supply. The 18V/9V switch lets you decide how much voltage is supplied to the drive channel. Use 18V when you need more headroom or output. Use 9V for more traditional overdrive and distortion characteristics.

The boost channel is completely independent from the drive channel. You can turn it on and off even if the drive channel is off. The boost channel is modular. The Crown Jewel has many different boost modules to choose from and we are adding more. Changing the module is easy. Just remove the back of the enclosure, pull out the old module from its socket, and plug in the new module.  The Crown Jewel comes with your choice of one.
