Guitar Tuner – What’s Inside A Boss TU-10 Clip-on Tuner

Not All Guitar Electronics are Made the Same

Inside a Boss TU-10 Tuner

After another accident occurred with this tuner I seized the opportunity to snap a photo after its casing instantly separated, probably somewhat in protest for the abuse it’s seen in the past few years.  This thing must be cursed.  My spider senses are suggesting that this is guitar tuner karma playback.

I had previously written about a few things I didn’t like this clip-on tuner (need I state “clip-on”), however, in all fairness, it isn’t a bad tuner.  God only knows how tough this little fucker is.  It definitely has that Boss toughness about it; ‘tis indeed robust like other Boss products.

Enough with the yaddy yaddy yah and here’s what it looks like in the disassembled state:

Now I have to bring to your attention that the scuff marks that show are explained by the fact that it had been lodged under my treadmill for about a year.  At some point, under the impression that one of the boys’ friends must have stolen it, I must have forgotten that I lodged under the treadmill to keep her steady.

As you can see, the electronics appear to be more advanced than your uncle’s HAM radio assembly kit or Forrest Mims III Radio Shack electronic guitar projects.  There is clearly a multi-layered, lead-free (RoHS), printed wiring board using SMT (surface mount technology), a 100-pin custom ASIC, and safety markings (UL Recognized) for UL 94V-0 flammability ratings. Most of the electronics sub-assembly is automated. The only manual assembly appears to be the soldering of the microphone (red and white wires seen on the left of the assembly).
