Sound — 9
This thing is sweeeet! The high output from this thing sounds awesome through any kind of amp (ESP. marshalls obviously). I use it through some wee rubbish Vox that I have but, even still, it sounds really cool. It's incredibly balanced and offers really low, punchy tones as well as a really clear sound up high. It's reeaally good for palm muting btw; something my stock pickups were lacking. I've got it in my bridge position but I think you can get neck position ones too. All I would say is that it's not very warm when put through a clean tone, might just be me though.
Overall Impression — 10
I got this put in my guitar to replace the stock pickup that was in the bridge (got an APH-1 in the neck) and it definitely upgraded my guitar. It could have been a completely different guitar for all I knew! I've got a Spear Gladius (awesome btw) and they work perfectly together. Price-wise, the JB is really good value for money. I'm not sure how much it costs in other places, but where I got it, it was the cheapest Seymour Duncan there. I'm really glad my friend recommended it to me and I would pass the recommendation on to anyone.
Reliability & Durability — 10
Trust me, there's a higher chance of the headstock of my guitar falling off before this pickup fails. For the price I paid for it, I am seriously impressed. It seems to be built like a rock and I would definitely recommend it to anyone. I totally rely on it and I think it should last the complete lifetime of my guitar.
