I wanted to give my deepest gratitude to all of the people who have visited this blog in 2015.  My statistics for visits and engagement aren’t massive (and I don’t expect that), but they exceeded my goal by more than 200% and my total page views were more than a 4000% increase over 2014.

In particular, the members of the Mesa community at The Boogie Board have provided inspiration, feedback, questions, critique, and support that helped shape the way information was presented in regard to the articles about the Dual Rectifier.  Thank you, very much.

As well, a handful of people from the Music Electronics Forum visited to check my work and I am incredibly grateful for the time and feedback from those who helped.

I hope everyone has an awesome 2016.  Cheers.

Nchannel depletion mode Mosfet exampleI’m thinking of a way to mute the dry signal from the parallel loop in my Mesa Dual Rectifier Solo 100.  There are already a few widely distributed mods, but none keep the functionality completely intact.

The depletion mode mosfet is a closed circuit when no power is applied to the gate.  When the bias voltage appears on the gate (at the same time it opens up the jfets), the channel between source and drain will pinch off, muting the dry signal.  I’m not sure exactly how to do it, but this is an idea I’m working on.

(EDIT)  Since beginning this, I found it practically impossible to get the correct Mosfet to implement this idea as it is.

Vintage humbuckers and those which emulate P.A.F.-style humbuckers have a distinct dip in the midrange, due in part to the unbalanced DC resistance of the coils and the number of winds on each bobbin.  Many modern humbuckers are over-wound, but still have an unbalanced pair of coils to produce a “P.A.F.-on-steroids sound”.  Many other modern humbuckers are fairly well matched, giving the pickup a spike in the midrange.  The Seymour Duncan SH-4 JB is one such pickup.  At a total DC resistance of 16.4k, it’s more than twice as powerful as a P.A.F..  My idea was to create a permanent offset and have a spin-a-split that doesn’t reduce to zero.

I like both active and passive humbucking pickups for different reasons.  Quality passives have a creamy, “I-Can’t-Believe-It’s-Not-Butter” character that actives usually do not have, but actives have clarity and punch that passives usually do not have.  Then there’s the EMG JH James Hetfield Set.  It doesn’t sound as compressed and hi-fi as many other actives while retaining the punch and clarity.  I love using them and recommend them to anyone for almost any humbucking sound.

This is a place for me to keep all of the music related things in one place.  Among the things I will be uploading are: DIY effects, tube amp circuit information, guitar wiring mods, guitar tab, ideas, and vanity bullshit.  I don’t mind if anything is shared, tweaked, insulted, or otherwise used as long as it’s not-for-profit and I’m credited/vilified for my ideas.
