This guitar started life as a brand new Harley Benton TE-20 SB Standard Series Electric Guitar and has been professionally customised by myself to incorporate a LED infinity mirror. 

The guitar was purchased from the Thomann online store specifically for the following modification :-

  • The sunburst guitar body has been precision milled using a CNC machine to create a semi-hollow body. The depth of milling has been minimised to retain good body strength whilst the guitar is under tension by the strings. 
  • An addressable RGB LED strip has been fitted around the inside perimeter of the semi-hollow body, held in place by 3D printed black PETG grips. This design allows for easy replacement of the RGB LED strip if required.
  • Two CNC milled acrylic mirrors fitted inside and on top of the semi-hollow body.
  • Hot Rail humbucker pickup fitted for minimal noise.
  • Original Harley Benton volume pot, tone pot and jack.
  • ***Neck pickup fitted for sound to light effect***.
  • The back of the body contains the battery power switch and housing for four 1.2V AA NiMH rechargeable batteries (NOT INCLUDED) and the ATmega microprocessor. These are enclosed by a 3D printed black PETG cover. Access for inserting/removing of batteries can be achieved via the sliding 'maton design' silver logo cover.
  • The RGB LED light strip can be controlled using the keypad (CR2025/CR2032 battery included) which is held in place by a 3D printed black PETG surround fitted to the back of the guitar body.

The above modification allows for normal use/playing of the guitar with no extra connections (e.g. USB or external power supplies). 

The fitted RGB LED strip is rated at 5 Volts and therefore four AA 1.2 Volt NiMH Rechargeable batteries are required:- 2500 mAh (or more) batteries are recommended and should keep the LEDs lit for around 3 hours when the LEDs are all white. However, choosing to light only red LEDs, for example, will minimise the battery power consumption and hence the LEDs operate for longer.


I have designed this guitar modification for the performing musician, hence it is robust and looks incredible on stage. However, this guitar could also be used as decorative wall art in a shop, restaurant etc...e.g. with a little soldering and basic electrical knowledge, one could further mod the guitar to run off a d.c. 5v (2 Amps or more) power supply instead of batteries.

Please note the image showing a very minor 'ding' on the side of the body...thanks to the C.N.C. clamps! The string height/action measurement images are on the 12th fret. The guitar weight is approximately 3.2Kg (was 3.3Kg before the mod). 

The price for this item is based on:-

  • time for research/development,
  • the cost of extra hardware parts + Harley Benton guitar,
  • time spent designing the CNC files,
  • milling time, 
  • time designing the 3D printed parts,
  • 3D print time,
  • assembly and testing,
  • Reverb fees.

Please do message me if you have any questions/queries:-)

The guitar will be posted in a sturdy cardboard box (and inner cardboard box) with further paper packing. So double packed;-)
