Cerulean Drive

Project: Cerulean (Bluesbreaker)
Variant: Morning Glory

Build description

This a great mid-gain, transparent, punchy drive! Can be touch sensitive, and the tones that can be coaxed out of it cover a wide range. Absolutely loved how small the pedal is too. I couldn’t find a ton of info on the clipping types in a Bluesbreaker so I socketed one of the clipping sides and that allowed me to try virtually all of the clipping styles.

YouTube demo:

Clipping used in demo:

  • No Clipping
  • Silicon Clipping (Stock Bluesbreaker)
  • Mosfet Clipping
  • LED Clipping
  • Silicon Clipping (Stock TS-9)
  • Asymmetrical Clipping (Boss SD-1)

Modifications or part substitutions

Ended up using the mosfet clipping on the mod side of the clipping selection. Bright cut is what was suggested in the directions. Presence/Treble trimmer moved to the outside of the pedal.

Morning Glory Clone

Project: Cerulean (Bluesbreaker)
Variant: Morning Glory

Build description

Built to the Morning Glory specs. Used the 2N7000/1N34A (Zendrive) second clipping diodes configuration. Built with clickless footswitch.

I had an issue with this build. The circuit would cut out when the Bright Cut switch was engaged. It took quite a bit of troubleshooting to figure it out. If you look closely at the third picture you’ll notice that my third jumper wire from the switch is being impaled by the ground pin of the IC! Once I lifted it off that pin, it worked perfectly. 🙂

Marshall BB mk1

Project: Cerulean (Bluesbreaker)
Variant: Bluesbraker mk1

Build description

I chose to make a mk1 bluesbreaker. Man what a quality sound. Building it was supereasy. Used boardmounted pots for the 1st time, which results in a superclean build.

Joyful Noise

Project: Cerulean (Bluesbreaker)
Variant: Morning Glory

Build description

This is the Cerulean Pcb, modeled after the morning glory. It is a much brighter pedal than I thought it would be considering I play with a morning glory on a regular basis. Overall excellent quality from Kevin. Will probably change out some resistor values to take out some brightness. Outside of that, it’s a great build!

Modifications or part substitutions

Volume mod, High Gain mod, Bright Cut mod, Diode Clipping mod.

Morning Zen

Project: Cerulean (Bluesbreaker)
Variant: Morning Glory and ZenDrive

Build description

Did the Morning Glory mods from Kevin’s documentation (great resource). I would say the “Bright Cut” mod is a MUST for this pedal. Even after adjusting the tone on the pedal, my ES-339 was very harsh coming out of a Blues Jr. amp. As soon as you hit the bright cut, it mellows out perfectly. I chose to put the ZenDrive transistors and diodes on the other set of pads for the clipping mod. With my setup, the ZenDrive has a little more cruch/growl than the Morning Glory. I am brand new to the electric guitar scene, and these two tones will be great for my developing arsenal. Excellent product! Perfect amount of direction through the documentation. Great experience for my first build. I can’t wait to build more.

Modifications or part substitutions

Morning Glory; D1-D4
ZenDrive; D5-D8
Bright Cut Mod.
Put the Presence pot on the outside (I had a little trouble with the lugs touching the back plate – but it was the only place I could put it after using the enclosed jacks.)

King of Sweden

Variant: 2-channel King of Tone clone

Build description

Great transparent overdrive. Built the King of Tone variant with diodes sourced from the Netherlands via ebay. Currently have the right side set to soft clipping and the left side as clean boost.

Marshall BluesBreaker MK1v1

Project: Cerulean (Bluesbreaker)
Variant: MK1v1 (early model MK1)

Build description

Smoothed out the overdrive by making the original, original spec (aka MK1v1) for R2, R3, and C2. I also was looking for John Mayer-like overdrive tones and judging by pictures of his BluesBreaker and educated guesses about his rig, he’s likely using v1 specs. It really smoothed out the drive and overall tone for my single coil Stratocasters. It really is a good illustration of a “transparent overdrive” where single notes ring and chords bring out the overdrive.

Modifications or part substitutions

I didn’t trust the 1N914 diodes (the yellow ones) from Tayda since I didn’t see many Google results for 1N914s with yellow bands so I bought NOS ones and put them in the alternative diode section. Instead of putting a switch in, I hard wired the alternative diode section direct to the output block. The presence is dialed all the way down so it’s a short. As true to MK1v1 as I could but with high quality parts and PCB 🙂

Modifications or part substitutions

More Gain Mod
TS9 Clipping
Stock Morning Glory Clipping
“Fat Mod” – Change C4 capacitor value to 20nf or 30nf for more mids!

Variant: Mostly Morning Glory

Build description

Here is my take on the Morning Glory, with a few of the mods that started on the POT. The graphics are how I usually see a sparkler used, UV printed at Pedal Parts Plus. The photos are of the first one I built, a friend ended up buying it. I made another for myself, and it resides on my pedalboard.

Dual Drive: RAT/Morning Glory

Project: Cerulean (Bluesbreaker)
Variant: Morning Glory

Build description

I threw this thing together the other day!
The build was super easy to follow and do. I used the Morning Glory specs and heck does it sound killer. Adds the perfect light gain without compromising my clean tone. And it actually pairs really well with the RAT. 10/10

Morning Glory

Project: Cerulean (Bluesbreaker)
Variant: Morning Glory

Build description

I always wanted to have a Morning Glory but couldn’t afford it. The Aion PCB of the MG is fantastic and the end result sounds amazing!
On the whole i use 3 different drive’s from Aion:
my 1. Stage is a ODR-1
my 2. Stage is my MG
my 3. Stage is a Klon
This combination works perfect and I’m very happy with my board now!
I gave my best to build a Morning Glory Looking Morning Glory

Custom Overdrive build

Project: Cerulean (Bluesbreaker)
Variant: Morning Glory plus

Build description

Cerulean built to Morning Glory Specs. Used the Bright Cut mod, High Gain mod, External Presence control, Used a separate foot switch for the clipping diode selection. It’s a 4PDT foot switch on a “Two-Knob-Job” board from Barry at GuitarPCB.com
I had to trim off a little bit of the board as it’s intended for a 3PDT switch and the fourth row of contacts needed a little room. So, the extra foot switch not only selects clipping diodes but also selects between two gain pots. Green and Red with indicating LED’s to match.
Clipping options used were four 1N914’s symmetrical and 1N34A germ/2N7000 mosfet (zendrive)
Glow in the dark paint under the decal. (couldn’t get a good picture but it looks really cool)
Realized I don’t have a gut shot so I could update this later…..
It’s a bit messy with a ton of off-board wiring to accommodate the layout.

Variant: Morning Glory

Stock Morning glory with Bright Cut and fat mods, stock clipping and Mosfet clipping. this sounds soooo good! I’ve built the King of Tone variant as well, I personally prefer this to the KoT.
