12V Electric Mistress

As a David Gilmour fan, I wanted to build an Electric Mistress to get the live guitar tone from the Animals and The Wall era. The 9V Electric Mistress project from the DIYStompboxes forum (markusw) seemed like a nice starting point. I run my own on 12V (upped the zener diode) instead of 9V. I built this about 2 years ago, when getting a SAD1024 was still possible (though very difficult, paid 20 euros for mine). Today finding a SAD1024 is almost impossible, so you might want to try a MN3007 retrofit. Below is the project file and a picture of my finished stompbox.

Voodoo Vibe

I wanted some chorusy vibe and tremolo, and Roger Mayer’s Voodoo Vibe offered a lot of features in one pack. This was the first time I etched a PCB, and was very surprised that everything turned out so well. It is a very complex project, but the sounds are amazing. For help and mods check out this thread on FSB.org.

MI Audio Crunch Box

I was looking for some Marshall-like distortion and the MI Audio Crunch Box seemed attractive. I mounted the clipping LEDs externally, so they light up as you play harder (a nice effect). The enclosure has an ugly swirl paint finish.

Ross Compressor

To extend my pedalboard and add some sustain to my sound, I decided to build a compressor. Having heard good things on the Ross Compressor (variant of MXR’s Dynacomp), I decided to try to build one. I used the schematic from Fuzz Central, and a layout by R.M. Rivers (note that capacitor C13 has incorrect (reversed) orientation on the layout).

Dark Side of the Fuzz – A BC108 Fuzz Face

Inspired by the heavenly guitar tone on Pink Floyd’s Dark Side of the Moon, I built a Fuzz Face based on Phillip Bryant’s Axis Face. I used BC108 transistors and made a DSotM inspired artwork. Below is the schematic, layout, and some pictures of the finished stompbox.

Krogerus Bluesmaster – 5E7 Bandmaster Build

In the summer of 2009 I finally finished my guitar tube amplifier build. The amp is based on Sean Kilback‘s modified Fender 5E7 Bandmaster schematic. The modifications include a grounded power cord, modified bright cap, PaulC phase inverter mod, Pre-PI master volume, a bypassable extra gain stage, and variable bias. The schematic is below (click to enlarge):

 

I used a modified version of Ceriatone’s 5E7 layout (sorry, only have original layout):

Here is some info on my build:

1 * 5751 (First preamp tube)
2 * 12ax7 (Second and third preamp tube)
2 * 6L6GC (Power amp tubes)
1 * 5U4GB (Rectifier)

Uraltone TV17 power transformer
Hammond 1645 Output Transformer

Sprague Orange Drop and Atom capacitors

Carbon Film resistors

Power: ~30W

American IPA – Second Attempt

Here is my second attempt on making an American IPA. This time I wanted some more sweetness, so I added some Crystal Malt, and more hop flavor, so I increased the amount of late hop additions. Below is the recipe, targeted values and a couple of pictures:

Recipe:

1.7 kg Coopers Traditional Draught
1 kg Light Spray Malt
0.5 kg Extra Light Spray Malt
1 kg Maris Otter Pale Ale Malt
300 g Crystal Malt
Wyeast 1056 starter (and US-05 as backup if fermentation doesn’t start)
10g Cascade @20 min
10g Amarillo @20 min
10g Simcoe @20 min
10g Cascade @10 min
10g Amarillo @10 min
10g Simcoe @10 min
10g Cascade @5 min
10g Amarillo @5 min
10g Simcoe @5 min
10g Cascade @0 min
10g Amarillo @0 min
10g Simcoe @0 min
25g Cascade @Dry Hop
25g Amarillo @Dry Hop
25g Simcoe @Dry Hop
25g Citra @ Dry Hop

OG 1.062
FG ? (estimated 1.015)

22L, IBU ~55, EBC ~18, ABV ~6.5%

The probable label. Name and color scheme inspired by Pink Floyd.

Hopefully the beer turns out good. It’s been a week in the fermenting vessel, will add dry hops in about two weeks and bottle in three weeks.

American IPA – First Attempt

My first attempt of homebrewing. I was attempting to make an American IPA inspired by Sierra Nevada’s Torpedo Extra IPA. The result was a quite fruity and bitter beer, but I felt it lacked a bit of hop flavor and sweetness. Below is the recipe and some pictures of the brewing process.

Recipe:

2 * 1.7 kg Coopers Traditional Draught
0.5 kg Light Spray Malt
0.5 kg Amber Spray Malt
US-05 Yeast
15g Cascade @20min
15g Amarillo @20min
10g Citra @20min
15g Cascade @5min
15g Amarillo @5min
10g Citra @5min
25g Cascade @Dry Hop
25g Amarillo @Dry Hop
20g Citra @Dry Hop

OG 1.059
FG 1.010

25L, IBU ~65, EBC ~13.5, ABV ~6.4%
