What’s Your Favorite Mod? (Here’s Mine.)

How am me make guitar thing better?
How am me make guitar thing better?

What’s your favorite guitar mod? The kind that changes how you play. One you’ve become so accustomed to that you wince when you pick up an axe that lacks it?

I’ll choose pickup wiring mods as a starting point: During the year that Seymour Duncan sponsored tonefiend.com, I devoted many posts to the under-appreciated wiring schemes I found in the company’s wiring diagram database. Some faves:

…and of course, the suicidal soldering mission known as the Pagey Project.

I’ve still got the “advanced” version of the Pagey wiring in my nothing-special beater Les Paul, and I like it so much, I want to fix up the guitar so it feels as nice as it sounds.

But of all the wiring experiments I tried, my absolute favorite is one that doesn’t appear in the Duncan archives: the so-called “PTB” tone control (for “passive treble and bass”). It’s a cliché to call a neglected idea “ahead of its time,” but in this case, it happens to be true. Being able to roll off lows as well as highs is unbelievably useful when sculpting sounds. It makes me want to run into the nearest Bain Capital Guitar Center, grab players by the collar, and shout, “You need to know about this!” (But I probably won’t, ’cause G.C. customers aren’t accustomed to receiving that sort of personal attention, and I wouldn’t want to freak them out.)

Allow me to repost last year’s video, demonstrating the circuit in action:

Over a year later, I remain totally addicted to this circuit, and I recommend it to anyone who doesn’t require a guitar with independent volume controls per pickup. (Everyone, basically.) It seems especially relevant for drop-tuned and 7-string metal players who realize you must sometimes cut a little bass to keep the lowest register tight and articulate. And the circuit is a godsend when used with bass-heavy fuzz pedals (such as vintage-style Fuzz Faces). In fact, I’ve even been building the circuit into the front end of certain loud fuzz pedals for use with guitars lacking this magnificent mod.

But I remembered something interesting this week when I opened up the Hamer 20th Anniversary guitar used in the video:
