Théorie - Theory

 

 
Don't get shocked!

Here's a trick , it won't totally eliminate a shock but it will reduce it down to about 40 volts (Caution  this mod only works on the string ground, if you touch the output jack, metal knobs or other metal grounded objects on your guitar you may end up seeing stars)

Here's what you need

  1. A 220k 1/2 watt resistor (color code: red/red/yellow/gold)
  2. A .001 ceramic 500volt or better capacitor

Twist and solder the two components together, remove the bridge ground from the back of the pot, insert the cap/resistor between the removed ground wire and pot.

Evitez de manger une poignée de châtaignes!

Voici un truc qui n'élimine pas totalement les chocs dus à une mauvaise mise à la terre mais les réduiera à 40 volts. Attention , il ne vous protège que pour le contact avec les cordes et non avec les autres paties de la guitare.

Il vous faut

  1. Une résistance de 220k 1/2 watt (code couleurs: rouge/rouge/jaune/or)
  2. Une capacité céramique de .001 µF/500 volt ou plus

Otez la mise à la masse entre le chevalet et le potentiomètre et remplcez la par le nouveau circuit.

Keep The Highs

Ever notice when you turn down your volume pot that your tone gets muddy? Here's a cheap mod that will only set you back about .50 cents and will keep your tone. All you need is to add a .001 µf ceramic capacitor to your volume control across the outside lug (not the one that is grounded to the cover) and the center lug, this allows the highs to bypass around the pot instead of being sent to ground as you reduce the volume.

Ne laissez pas les aigus se tirer des pattes

N'avez-vous jamais remarqué que votre son devient molasson quand vous baissez le potard de volume. Une modif bon marché fera l'affaire. Une capacité céramique de .001 µF entre les deux pattes actives du potard dirigera les aigus vers la sortie au lieu de les laisser aller vers la masse quand vous réduisez le volume.

Midrange Modification

Here's a really cool mod for those of you that don't  use your tone control ( you always leave it full up right?). It's a mid cut control designed by Torres Engineering that replaces your tone control, actually it doesn't replace anything, it just rewires your tone control and adds a few parts. When you turn down the mid control is scoops out the mids yet leaves the lows and highs. You can experiment with the capacitor values to change the eq point that the mid cut effects. Just follow the diagram below, make sure the lead coming from the inductor to the outside lug of the tone pot is insulated (the other lead doesn't matter cause it's soldered to the back of the pot along with the tabs on the inductor-just make sure you have room for it on the side of the pot or solder it to the back of the pot).

Modifiez les sons médiums

Voici une modif vraiment utile pour vous qui laissez toujours votre potard de tonalité grand ouvert. Il s'agit d'une modif du circuit de votre contôle de tonalité qui le remplace par un contrôle des sons mediums, sans altérer les graves ni les aigus. Vous pouvez essayer différentes valeurs de capacité pour faire varier les points d'équalisation. Suivez simplement le shéma ci-dessous et assurez-vous que le fil entre la bobine d'induction et la patte du potard de tonalité est bien isolé. Assurez-vous égalment que vous avez la place suffisante à côté du potard ou bien soudez la bobine à l'arrière.
Pour la valeur de la self TL021, vous pouvez essayer 1.5 Henri, ou le double, ou la moitié. Alors deux selfs identiques de 1.5 Henri sont suffisantes pour vos essais.

A Switchable Boost / Cut Control

This Modification is a takeoff from the Torres Engineering Mid Boost / Cut control but with a twist. This is the same mod as the Midrange Boost / Cut mod but with a Push/Pull pot to allow the normal tone control functions when the pot is in the pushed in position and when pulled up it engages the Mid Boost / Cut control. Just follow the diagram (use a standard 500k Push/ Pull pot) and enjoy.

Le précédent avec un switch

Le potard de tonalité a été remplacé par un potentiomètre avec connecteur Push/Pull.

Cette modif permet au potentiomètre de tonalité de fonctionner, soit dans le mode classique (bouton poussé), soit dans le mode précédent agissant sur les sons médiums (bouton tiré).


 

Midrange Boost / Cut Modification

Here's another cool mod for your tone control designed by Torres Engineering. It's a mid cut / boost (sort of) control that replaces your tone control and adds a few parts. When you turn down the mid control it cuts the mids yet leaves the lows and highs. When you turn up the mid control it rolls off some Lows and highs and leaves the mids, so it sounds as though you added mids. The only way to truly add anything is to have a active eq or preamp installed (which requires a battery.) Just follow the diagram below, make sure the lead coming from the inductor to the Resistor/Cap network is insulated (the other lead doesn't matter cause it's soldered to the back of the pot along with the tabs on the inductor, just make sure you have room for it on the side of the pot or solder it to the back of the pot).

Coupure ou augmentation des sons médiums

Voilà une autre modif pour votre contrôle du son, présentée par Torres Engineering. Il s'agit d'une sorte de contrôle fort/faible des sons médiums qui remplace votre contrôle de tonalité en ajoutant quelques composants. Quand vous fermez le contrôle de médiums, vous affaiblissez une partie des graves et des aigus, ce qui est perçu comme une augmentation des sons médiums.

 

 

Midrange Boost / Cut Modification

Here's another cool mod for your tone control designed by Torres Engineering. It's a mid cut / boost (sort of) control that replaces your tone control and adds a few parts. When you turn down the mid control it cuts the mids yet leaves the lows and highs. When you turn up the mid control it rolls off some Lows and highs and leaves the mids, so it sounds as though you added mids.

Coil split with a twist

How about a variable coil splitter for you humbucker users out there (sorry single coil users). Adding a splitting switch (mini toggle or push/pull) gives you only 2 options, full humbucking mode or single coil mode. This modification will use your tone control as a variable splitter giving you all the sounds in between full on and off. I have 2 versions of this modification available, just click on the one that best suits you and the rest is up to you.

  1. Use a stock tone pot for a variable split only

  2. Use a Push/Pull pot for a stock tone setup or variable split option (My favorite)

Variable coil tap #1

This modification is really simple to do but the only drawback to it is that you loose your normal tone control function, but hey who uses it anyway! OOPS didn't mean to offend you folks that do use your tone knob, if you do use it please check out modification #2. The rest of you that stuck around just follow the diagram below and it will work fine

Variable coil tap #2

Now we're talking my mod of choice for a coil split. This modification utilizes one of the best (my opinion) inventions for electric guitar, the Push/Pull pot. With this mod we will be able to have a standard tone control (just as it is on your guitar right now) with the knob in the down position, or the variable coil splitter when you pull up on the knob (or it could be wired just the opposite). Just follow the diagram carefully and it should work fine.


Combo Tone / Midrange cut

Here's my varaition on the Torres Mid Cut Mod that uses a Push/Pull pot and the same parts as the Mid cut mod. This setup will give you a stock tone control with the knob in the down position and a Midrange cut in the pulled up position. Note this modification (and all others on this web site) are based on a standard DPDT (Dimarzio) Push pull, what I mean to say is that when the shaft is in the down position the contacts being made are the middle and lower two. When pulled up the middle and upper two contacts are made. (I have worked with some pots that are just the reverse!)


Add a Pickup

Have you Strat owners ever wanted to get that "Middle position" Tele tone from your 3 pickup guitar? Now you can by activating your neck pickup in conjunction with your bridge pickup! What you will need is either a 250K Push/Pull pot (my favorite-no drilling any holes in that "57 Strat" or giving away your tone trick) or a mini SPST toggle switch. If you study the diagram below you will see that all we are doing is replacing one of the stock tone pots (your choice) with the Push/Pull control and adding a wire from the 5-way switch at the point where the white wire from the neck pickup connects and running it to the Switch portion of the Push/Pull and then to the outer lug of the volume pot.The tone control section of the Push/Pull wires the same as the pot that was removed.

What this allows you to do is to turn on the neck pickup when you are in the bridge pickup mode (or if your in that "classic"one up from the bottom #4 position) you will have all 3 pickups at once!
