This is Leonardo da Vinci’s invention: a harpsichord, an organ and a viola da gamba. Hear this 500 year old instrument come to life for the very first time. This amazing recreation by Sławomir Zubrzycki is the result of a 5,000-hour project.
Question: Which solid body guitar has better sustain, the Fender Stratocaster or the Gibson Les Paul? If you were like me, you’d probably pick the Les Paul. I’ve taken it as plain truth that there’s no competition: Gibson Les Paul = incredible sustain. Boy, was I so wrong!
An article by Mottola, R.M. “Sustain and Electric Guitar Neck Joint Type”, piqued my interest. Mottola, in his experiments performed power analysis, spectral analysis, and listening evaluation on three types of solid body electric guitars with 1) Bolt-on neck construction 2) Neck-thru construction and 3) Set-neck (glued-in) construction.
We got the initial batch of our custom-designed coils from Chipsen!
- 1300 turns (0.040mm, AWG 46)
- 450Ω D.C. Impedance (Max),
- 20Hz-20kHz flat frequency response
- 9mm diameter, 5mm height.
Hello! We’ve been busy. It’s been a while, but we are inching slowly, but surely, towards production. Let me present the Six Pack production prototype (v1.4). If you have been following this project, you will notice that this is very similar to the Six Pack version 1.1 prototype apart from a few design changes.
- Six low impedance coils (1300 turns, 350Ω D.C. Impedance, flat frequency response, 20Hz-20kHz).
- Modern, Low power, Low noise OPA2314 differential Op Amps.
- Single supply (1.8 V to 5.5 V).
- Stainless steel height adjustment screws and springs.
- Premium gold-plated, 2 mm pitch header connector.
- Precision 1% thin-film, low TCR, low noise, Yageo and Vishay resistors.
- Panasonic low noise film capacitors.
- Fender Stratocaster Profile (14 mm total height excluding connector).
- EMG style pickup enclosure.
My observation is that in general, guitar players are conservative when it comes to guitar sound. I think that is the reason why digital emulations of amplifiers, speaker cabs, pickups, guitars, etc., are quite popular, for example. Take the Roland VG guitar. You see emulations of electric guitars, acoustic guitars, all sorts of amplifiers and speaker cab emulations, all sorts of pickup emulations (single coil, double coil), effects emulations, even microphone emulations and placement, etc. The same can be said of all the current generation plugin effects available for computer based recordists.
Some of you probably know that I am a C++ programmer. I am a consultant at Ciere Consulting. I am a strong advocate of Open Source since 1998. I am active contributor to the Boost libraries, a peer-reviewed, open collaborative development effort. I am the author of Boost.Spirit, Boost.Fusion and Boost.Phoenix. This is my C++ Now 2013 talk “Joel de Guzman: Inside Spirit X3: Redesigning Boost.Spirit for C++11″.
I know… this hasn’t got anything to do with guitars but this is the other side of me anyway…
After countless hours experimenting and iterating over the basic design, I think I’ve reached a point where I have something that am actually finally satisfied with. Here now, let me present version 1.0 of the Six Pack Hexaphonic Pickup.
Our Op Amp Shootout has been updated to reflect recent research and development. The previous favorites are now replaced by better choices and there are more choices to choose from depending on requirements from highest performance and highest power, to moderate performance and low power.
Check out the the Op Amp Shootout page. The page is continually being updated. The Op Amp table is maintained as a linked Google Doc Spreadsheet.
This is part 3 of the “Let it breathe” series. For proper context, you might want to check out Part1 and Part2. This third and last part of the series concludes with actual frequency response measurements for various coil configurations of the Hexaphonic Pickup Project and with the Fender Stratocaster middle pickup as benchmark to compare against. In addition to standard windings with 500, 1000, 1500, 2000, 2500 and 3000 turns AWG 42, we also tested bifilar windings (see Alternative Ideas) with 500 and 1000 turns AWG 42. Like before, the low-power LME49726 OP Amp is used in the differential preamp stage with a gain of 5.
