ProTone Body Rot II

The spiel on this slightly modded Krank Distortus Maximus:
If you’re tired of the metal distortion pedals mass produced in Asia, designed by guys in their late 50′s that have no idea how metal sounds TODAY, then you NEED to hear the Body Rot II. In case you hadn’t noticed, metal is what we do… its what we are.
The Body Rot II started off with the heart of the original Body Rot distortion pedal with some added tone shaping EQ… but we knew that wasn’t enough.

With so many boutique companies jumping on the ultra heavy distortion pedal band wagon Pro Tone had started with the Body Rot distortion, we knew we had to create something massive. We knew that the Body Rot II had to be something that would send a jolt to the competition and silence the naysayers. The Body Rot II Continues to do just that.

Earthquaker Devices Monarch Overdrive

30th October 2014 - Put on hold pending investigation :o)

Info about the original:

The Earthquaker Devices Monarch Overdrive is an FET, all discrete dirt machine that will get you some truly vintage and organic overdrive. The Monarch Overdrive is based on a certain UK hard rock amp's input stage that shares the same color as the Monarch's brilliant design. This pedal provides high gains that are largely compression free, for a truly organic and natural sounding overdrive tone that really gets the sound of an overdriven vintage amp. The treble and bass controls are essentially frequency boosters, and not simply the run-of-the-mill roll off filters found in most all overdrive pedals. These controls are centered in the preamp section and really provide some depth to the tone and overdrive characteristics of the pedal. This provides you with a solid bottom end and clear and crisp top ends for rich harmonic overtones that ooze vintage overdrive. This is the overdrive pedal to get for larger-than life fat chord work and a thick and significant bottom end. The Earthquaker Devices Monarch Overdrive can also be used with higher voltages to yield more headroom, a fatter and more focused tone and a wider gain range.

The Earthquaker Devices Monarch Overdrive is one thick and meaty overdrive. Taking the best elements of a vintage UK rock amp, this pedal delivers some balls-out tone. As with other Earthquaker Devices, you have some real control over the tonal characteristics of this overdrive, by boosting frequencies rather than rolling them off. The Monarch Overdrive gives you some real vintage overdrive, but also some real tonal variety when you call for it.

Features:
    Gain: Controls the amount of overdrive
    Level: Controls level of output
    Treble: Boosts highs
    Bass: Boosts lows
    Power: Regulated 9-18v power supply with negative 2.1 mm center barrel

Joe Davisson Antiquity Fuzz

Noticed this one and thought i'd do a quickie. Here you go with Joe Davisson's improvements on the classic fuzz face.
Note from Analog Alchemy website:
Placing a diode at the input of a silicon Fuzz-Face type circuit improves the tone by preventing saturation of Q1. Adjust the 5.6k resistor until Q2's collector is near 4.5v for the best sound

EHX Hot Tubes

Another one that was missing from the library. Original units call for 2M pot for the overdrive control, but as the demo below suggest, the middle position of that knob should be mild enough. So i see no harm in using 1M pot for that instead. That'll give you the latter half of the sweep.

...aaand i built one for myself. 1M lin pot for the drive works really well. At minimum setting the effect is slight overdrive with a nice tube sounding overdrive going on. When maxed it's a very high gain driver and sounds really nice. I think i may need to get myself an original nano version to compare them. But yes. This sounds very good. One more thing. I usually sub log volume pots for linear as i like the sweep better. On this one. Nope. You'll definitely want it to be logarithmic.

Boss CE-2B

And I may as well add this one as a separate layout so we know what versions the comments are based on.  This changes a cap value and adds an Effect Level pot to the CE-2.  If you want to add an Effect Level pot to the guitar CE-2, just use this layout and swap the 12n cap to the left of Q3 for a 33n.  Or if you want the option of using both, use a DPDT on/on toggle like this:

1---4
2---5
3---6

Solder a 12n between 1 and 4, solder a 33n between 3 and 6, and connect wires 2 and 5 to the holes that the 12n should have connected to on the board.

This obviously isn't yet verified but it's so close to the guitar version that it will be good to go.

The BOSS Bass Chorus CE-2B is designed specially for a bass guitar, giving you the best result when used with a bass guitar.

The Rate, Depth and the Effect Level knobs serve to create various chorus effects.
