Just wondering why the .33uf, 400V metal film capacitor add that's used in the Shielding The Beast mod isn't done more often or to more guitars, like an LP style for example. It seems like an easy thing to do and it might be worth it. Am I missing something?

you're mistaken. the QTB mod CAN be used for ANY guitar as long as it's electric. It's just a coincidence that JA uses Strat and Tele as examples.

I understand the process can be done to other types of guitars, but I just never seem to hear about it being done to different styles of guitars. It seems whenever I see pictures or hear people talking about STB, it’s in regards to a strat or tele. If anyone has done this mod on other styles of guitars please speak up. I think shock protection is important to be aware of. In addition, can anyone help explain how they did it, particularly adding shock protection to an LP style guitar? Would one simple way of doing the strings just be putting the capacitor in series with the bridge ground wire?

My bad; I misunderstood your question as "Why don't guitar manufacturers do that?" I understand the process can be done to other types of guitars, but I just never seem to hear about it being done to different styles of guitars. It seems whenever I see pictures or hear people talking about STB, it’s in regards to a strat or tele. Although there are other guitars with singlecoil pickups (including some LPs), Strats and Teles (and all their clones) are among those most in need of "Quieting." ("Silencing" a guitar is probably something we'd only do by accident. ) Absolutely. That's why John A. gave it so much attention on his site, and why my gear bag includes a GFCI "triple tap" like those shown partway down the left side of . If I do nothing else to mod any of my guitars, all of them will have a "safety cap" in them. If you check the page , down below " Pictures," it mentions putting a small Mylar capacitor between the bridge ground and the copper shielding in the body cavity. (Works if you used copper foil or something else that the cap can be soldered to.) Here's another page that tells how to install the cap-and-resistor combo that John A. makes mention of on his page: singlecoil.com/docs/shock.pdf . The Singlecoil.com PDF also includes some of John A.'s writings on the subject. HAS Sound sells a cap-and-resistor circuit called the "Zap Trap" www.has-sound.com/index.htm, and notes: " The Zap Trap only works on the instrument's string ground. Other metal parts that may come in contact with ground but are not associated with the string ground (jacks, metal knobs, etc.) are not protected by using this mod!"

I added the cap to my SBA when I installed Dream90 pups. Shielded everything & installed it exactly as JA described - only difference was that the guitar wasn't a Strat or Tele.

I just found the Single Coil site recently as well. Interesting to say the least... I also noticed today that what the author of that says on his site is in Dan Erlewine's first book. I do also wonder why manufacturers don't do it---MSM, I think your answer is correct.

a few things need to be re-stated here:
the "shock protection" cap only protects you against D.C. shocks. in the rare event that your 1st pre-amp tube shorts from plate to grid, it will protect you.
but if your amp's ground is connected to A.C. hot (a much more likely failure) you will still light up like a christmas tree (see how i worked that seasonal reference in!) and smoke will still come out of your ears.
so it's a protection against a rare failure, and does not replace the importance of having a gfci.
while we're at it i guess i should also mention that even a gfci on your properly grounded amp won't protect you against the lethal current flowing from the microphone plugged into the hot grounded p.a. when your lips touch that and the current flows through your neck and chest to your hands and the properly grounded guitar and amp, you light up like a minora (ooooh! even got some p.corr. equal time in for our jewish friends too! )
bottom line here: there is no ONE magic bullet here. there are a number of things that need to be on your safety checklist at the gig.

magic bullet is using wireless i suppose there are other reasons why wireless is good or not-so-good. but from a strictly safety point of view, i stand corrected. you're absolutely right. wireless IS a magic bullet. unk

there are other reasons why wireless is good or not-so-good. you are thinking about nigel tufnel and his sex farm solo? ;D

(thanks for the laugh!) i was thinking about the compression that is usually built in to most wireless systems, the increased hiss, and other shaping that occurs when a wireless is inserted into the chain. in some cases those things work out as advantage, in others, not-so-much. can't think of any case where radio transmission bleed through is good for anything other than twisted humor. unk
