Reliability How has it stood up over time? As far as reliability we will have to find out. But I like that I don't need to replace a battery and still get great tone. Overall Your general opinion of this product. This is a great pickup. After my install I compared it to my Seymour Duncan Live wires. I found that the output was not as loud as my active pickups. But the tone was much more clear and heavy bottomed than the standard Seymour Duncan pickups I had. Even though they aren't as loud as my actives they still sound great. Playability and Feel How does it feel, Heavy, Fast, Chunky? How was the neck? Are the controls easy to get to while playing? Along with the great tone the responsiveness of these pickups are great too! Chunky without being muddy, bright without being tinny and not weak in the mids, very clear. Tone Bright and snappy? Dark and smooth? Were the pickups hot, mellow, thick, thin? great tone the responsiveness of these pickups are great too! Chunky without being muddy, bright without being tinny and not weak in the mids, very clear. Finish How did the stain or paint job look? N/A although I like the looks of these very unique!!! Action How was the action out of the box? N/A
