One of the most overlooked “hidden details” in the process of quality guitar construction is what’s lurking “under the hood”. When you purchase a mass-manufactured, “off-the-shelf” electric guitar, chances are you’re settling into an unnecessary compromise. 


The most fundamental aspect of a superior electric guitar is what’s hidden under that little back plate. Shielding, proper soldering/solder joints, careful assembly, etc., are the sorts of elements that should be of crucial priority, yet often aren’t. You wouldn’t buy a car without looking under the hood, so why would you settle for anything less than the best? 

The bottom line is that many manufacturers avoid shielding altogether to cut costs, leaving their guitars susceptible to radio and RF interference.  Using cheap components and labor to assemble control circuits can have a devastating impact on reliability, and more importantly noise reduction and tonal quality. 


Standard in all our designs are Fender Grease-bucket tone circuits.  These pots act as low-pass and high-pass filters simultaneously to root out irritating ranges.  In other words, Grease-buckets are known for smoothing out the harsher frequencies so that your tone is enhanced without the threat of becoming muddied by menacingly overpowering highs and lows.

An upgrade option for those looking to go a bit higher end is to choose our private stock of NOS 60’s Fender Correct Sprague Ceramic Tone Caps.

We always use full copper shielding, star grounding to reduce potential hum, and like we demonstrated in the wiring diagram, a fully shielded output (Something we simply haven't seen any other large manufacturer or other custom shop do.) 

A quick recap of the  Nystrum Guitar Electronic Assembly :

  • Full Shielding of Control Cavities
  • Silver Bearing Solder of All Connections
  • Silver Audiophile Wire with a Teflon Jacket
  • Switchcraft USA Jack
  • Electrosocket Output
  • Never Any Tone-Robbing Zinc Hardware Used



Ever give any thought to what your guitar has for a tone capacitor?  Confident that the manufacturer put in countless R&D hours evaluating & testing capacitors and installs a high quality cap that  complements your guitar's pickups ?  Unfortunately that's rarely the case,  most manufacturers use a 'one size fits all' same cap on every model. That capacitor becomes a simple voltage / capacitance specification for purchasing to source in bulk from the supplier with the lowest price.

If you look at the capacitors in vintage guitars from the 50's through the early 70's it's obvious that careful consideration went into tone capacitor specification for every model. 

At NYstrum we think choosing the tone capacitor for a customer's guitar is tantamount to the choice of pickups.  It is so important that our vintage parts specialist researched and identified capacitors that were installed in those great guitars from the past,  using the information to find & purchase NOS ( new old stock ) examples that we inventory and install in our custom guitars.
