Les paul Pickup upgrade and magnet swap (Seymor Duncan 59 and Pearl Gates)



Hello friends, Its a humbucker pickups upgrade. I've got tired of my Burstbuckers (not pro) 1 and 2 copy, then I bought a Seymour Duncan Pear Gates Bridge (A2) and a 59 neck (A5), I guessed the 59 sounded a little boomy (lot of basses). The end of the history, I've swaped the pickups magnets: Alnico 5 to Alnico 2.
Now I have a Pearl Gates A5 and a Duncan 59 A2. Showed at the video below:

0:26 neck; 0:45 bridge; 1:05 both pickups

Stratocaster tremolo piezo + piezo mod

This is a mod to adapt a under saddle acoustic guitar piezo to a stratocaster block tremolo anda a common piezo inside the guitar body.

 

  • Use a rotary tool and a file to make a groove at the upside of the block:

  • ... until the piezo fit it, with only a small part outside:

  strat block tremolo 


  • Screw the other parts of the tremolo with the piezo wire out of the block:

*Maybe you will have to file the wood of the guitar under the bridge, a litle bit, to adapt the extra wire.

  •  Othewise, if you don't use the tremolo arm, like me, it is possible to use the other side of the block, making a extra hole to pass the wire:

  •   Set up the tremolo at the guitar, use the grounding hole to pass the piezo wire and conect it to the guitar circuit. Some hot glue will fix better some parts:

  •  Next step....fix a common piezo at the inside of the guitar body, near as possible of the bridge, using a double face tape:

The tromolo piezo will have a lot of influence of the coils, producing a lot of reverbation. My sugestion is to mix the two piezos with a resistor (or a pot) like that:

 

strat piezo

* 1M or less... depends on the piezo output level.


Finaly, mixing the pickup mod (http://guitar4geek.blogspot.com.br/2016/06/stratocaster-wire-mod-series-pickups.html) with this piezo mod:

Stratocaster wire mod - in series pickups switch


Looking at the picture below, the first switch (mod 1) configures the pickups in series:
  • neck+middle (series)
  • bridge+middle (series)
Besides that, a second switch (mod 1b) inverts the middle pickup, making the sound thicker or thiner.

The mod 1 switch also connects the tone control to the neck+middle "fake" humbucker.

*All the pots are 500K, making a more open sound and helping the basswood body limited tone response.








  • Mod 1 ON, mod 1b OFF and strat switch in position A: bridge+middle with thin sound
  • Mod 1 ON, , mod 1b OFF and strat switch in position B, C, D: mute
  • Mod 1 ON, mod 1b OFF and strat switch in position E: neck+middle with thin sound 

  • Mod 1 ON, mod 1b ON and strat switch in position A: bridge+middle with thick sound
  • Mod 1 ON, , mod 1b ON and strat switch in position B, C, D: mute
  • Mod 1 ON, mod 1b ON and strat switch in position E: neck+middle with thick sound

This is a new face for the little cabinet of my 5F1 clone, I only take of the brown tolex and put in a yellow one (fender alike).

Lets see the tolex mod:

  • The old style

  •  Take it off
  • Lots of work
  •  New style

Boss MT-2 Metal Zone and Behringer UM300 Ultra Metal Mod


Mods for more thicker and compressed sound:

  • Change the DO04 and DO03 to Germanium diodes, or use a switch to select the original Se diodes or the Ge diodes. I have used two 1n60 diodes.

Boss Chorus CH 1 and Behringer UC200 Mod

Mods for more thicker effect options:

  • Add a toggle switch (on-off-on) to select the C18 values, this will change the delay time of the out of tune signal, before it is added to the guitar signal. The middle position will be off and only a 5pf (or 4,7pF) value is seeing by the circuit, no delay at all, the others positions will select two 0 to 100pF trimmers that can be adjusted as you wish, for a pleasant delay color. Adding more delay time, more thicker will be the chorus effect.
  • Optionally, reduce the value of C30 (or remove it) to upper the trebles, only in case of a dead tone problem.

*     In place of one trimmer, could be used the original 47pF capacitor.
**   Behringer have originaly  a 5pF in parallel to a 47pF (C18) capacitor.
*** The C18 mod is very famous in the internet foruns.

Boss Tremolo TR 1 and Behringer UT100 Mod

Mods for more tone options and balance the on and off stomp's volume:

  • Replace the R9 resistor from 10K to 18K (or more), to balance the on and off stomp volume. I've choose 18K.
  • Add a on-off-on toggle switch to select the C4 values (or no C4), this will make a subdued, but perceptive, diference in the effect tone. The middle position will select none capacitor, the Boss TR1 came originally with 0,1uF cap and the Behringer came with a 0,68uF eletrolitic cap. You can select 0,1uF, 0,68uF and none capacitor, or try out others values.
