I have already known the DiMarzio Chopper pickup. I had one in my Pink Paisley Telecaster's bride position. I really liked the sound of it. It is creamy and smooth, with a tasteful amount of extra gain and punch.
I decided to buy something to my Yngwie Malmsteen USA Strat. Yes, for an Yngwie Strat! Let's face the fact that the factory installed DiMarzio HS-3 and YJM pickups are still a single coil pickups (with dummy coil for noise cancelling) therefore it produces very low output. Well, I like the sound of them but for the type of music what I play they are not really suitable. As I wanted more output I focused on the Chopper option. I purchased one for a Neck position, and for the bridge I'm thinking about to buy a Super Distortion or Air Norton or maybe Tone Zone.
So one thing I can tell after install the Chopper to the Neck position: it is awesome!
Sing like an angel and screams like a devil. The good thing is: the tonality is very similar to the HS-3 / YJM pickups therefore it almost sounds the same, which I basically like, but the Chopper has more saturated, more compressed gain structure which I prefer. It is important to adjust the pickup height properly,, not too low, not too high. Nice pickup, thanks to Thomann to delivery it so fast!
