« Amazing technology »

I bought a Tronical system (called "mini etune" on the 2013 Gibson range) from an online German store to install it on my 2004 Gibson Les Paul std. I had to file the headstock holes a little bit to mount it but no big deal. Setup instructions are clear and the result is simply amazing. It is user friendly and you can switch from Drop D to E flat, DADGAD, Open G even custom tuning (the rain song from Led Zep) in a few seconds. It is adding a little 100 gr to the headstock vs the original grovers tuners. Like a lot of stuff, this is not indispensable but it is damned usefull !
