A David Gilmour Inspired Strat - Redux

A little over two years ago I put together a parts-caster using the EMG DG20 pickup set. This set of pickups was used by David Gilmour starting in around 1985 at the Live Aid concert. He'd continue to use the active pickups through about 2005 when he would return to the Black Strat and it's traditional single coils. When I first got the EMG DG20 together, it sounded good - by itself. Unfortunately most of the Gilmour sounds and pedals I'm trying to emulate are from the earlier albums, and the active pickups didn't stack well with my amplifiers and effects pedals. So given I have many guitars and this one wasn't being played - I had two options. I could try and sell it (the market for parts-casters as a unit is not good), or I could pull out the active pickups and re-wire it with single coils. After some unsuccessful attempts at the former, I settled on the latter, and I'm very happy I did!

The Dark Side of the Steggo??? A New Gilmour Inspired Combo Pedal!

 Combination pedals are a great way to get multiple amazing circuits in one box. I've built a few pedals that are either physical combinations of two separate PCB's, or clones of pedals that involved multiple PCBs in the past. However, all of these combinations were essentially clones of existing pedals that were combination pedals in their own right, including the Steggo versions of the Cheese Source, Hoof Reaper, and Heavy Water. However, I wanted to do something that was a combo of two different pedals to help create a specific sound, so I went back to the pedal board of one of my favorite guitarists, David Gilmour, for inspiration.

Cloning the Cornish P-2 - For Real This Time!

Pete Cornish's effects and pedalboards have been used by a wide array of guitar luminaires including David Gilmour, Tony Iommi, Brian May, Paul McCartney, and Mark Knopfler. While some of his designs are completely original, like the CC-1 Overdrive and OC-1 Compressor, other designs are based on existing circuits, like the SS-3 (loosely based on the MXR Distortion+) and the G-2 and P-2 (both based on the Big Muff Pi circuit using germanium and silicon diodes respectively). AionFX offers many Cornish boards, and as a fan of Cornish pedals, I've built many of them including the OC-1 compressor, the SS-3, and the G-2 (both in non-dino and dino versions!). Unfortunately AionFX did not offer a board for the P-2 and after hunting around, there were no commercial boards available. The only board I could find was the Effects Layouts version, which had the "probably" disclaimer and appears to have been based some speculative circuit diagrams on the net. I'd built a few pedals using hand-etched boards, both with and without the effects layouts Cornish buffer, and had really loved the sound. I still wanted to have a faithful clone of the original, though, and with a little gentle dino-sized nudging, PedalPCB has recently released the Polonium-2 board based on a trace of the actual P-2 pedal itself.

For a Pachycephalosaurus this counts as a "gentle nudge"

It's BMP Time Again!!! A '73 Gilmour Ram's Head Build for Steggo's Personal Board

I've definitely built more Big Muff Pi pedals than any other type, and in more variants. The circuit goes together well, and with all of the modifications over the years, there are a ton of options that can make subtle (and in some cases not so subtle) differences in the sound of the effect. Last November I finally came up with a suitably "Steggo" name for the venerable BMP, the Big Muttaburrasaurus Phi, or the "Big Mutt Phi" if you prefer. The enclosures I'd used were a modified version of an earlier take of roughly the same art that I'd intended on using with the AionFX Halo PCB that I've used on many successful builds. Since I had one of the enclosures for the Halo PCB available, I decided to go ahead and use it for a personal build - with only a few ulterior motives.

The Thagomizer 2 - A Cornish ST-2 Clone

So as promised in my recent Thagomizer I update, there is indeed a Thagomizer 2, and I'm presenting the prototype build today. The Thagomizer I is a cone of the Colorsound Power Boost - at this point built with all vintage components. The Power Boost is very closely related to the Colorsound Overdriver, which I'd also previously built - though with all modern components. I first became interested in both of these pedals when researching David Gilmour's effects boards. In later years, however, David worked with Pete Cornish to develop a custom integrated pedalboard - which Pete later released as distinct effects pedals in their own right. The ST-2 is a major overhaul of the original Overdriver circuit with different component values (and therefore different voicing), a double buffer like the G-2, and an op amp gain stage tacked on to the end of the circuit. With new copies running over $500 (with a long wait) and used copies starting at about $650 - this is yet another pedal that screams for a good clone!

EMG DG20 Partscaster Build

Fender electric guitars - especially the Stratocaster and Telecaster - by virtue of their construction lend themselves easily to modification. The necks bolt on, and in many cases the pickups are housed within the pickguard itself - so any modifications required fit a new pickup or even a totally new style of pickup don't require the skills of a high-end luthier. This fact quickly led to the birth of the "partscaster" - any Fender guitar that has had parts swapped, or even guitars built from parts from the outset. 

Prior to this build, I owned one Stratocaster - an overall black one with cream pickups - and yes it looks a lot like "The" Black Strat. As I'm (obviously) a David Gilmour fan, I also wanted to have a strat with the EMG active pickup set he started using in the mid-1980s. That being said, my existing strat is a special edition, and I kind of want to keep it stock. I therefore started looking for a way to build my own "partscaster" centered around the EMG DG20 electronics.

The Electro-Harmonix Electric Mistress Flanger / Chorus

I'll be completely honest, I'm not a great guitar player at this point. I'm somewhere in the "intermediate" range, but I'm having a huge amount of fun learning not only guitar technique but chasing great sounds. One of the songs I've always loved is Rush's "Natural Science," and the flange effects at the beginning of it really do a lot to set the tone and mood of the piece. While no one seems to have a definitive answer (apart from Alex Lifeson, who apparently hasn't discussed / disclosed what hardware was used), the consensus is that he used an EHX Electric Mistress on the album Permanent Waves - especially on "The Spirit of Radio" (another song I need to learn...). As I'm on a massive pedal-building kick, and given one of my other guitar heroes David Gilmour also used one, I decided to build my own EHX Electric Mistress using PCB Guitar Mania's Electric Lover Flanger PCB.
