Yeah, I was not saying the 498T was a JB clone. Just that it reminds me more of a JB than of a Custom 5. I actually find the 498T grittier/raspier, but also, slightly more open in both the highs and lows to offset that compared to a JB.
And I find the 500T more bitey/cutting/focused rather than bright, but yeah, it's easier to get it to sound harsh. Although the 498T can sound pretty harsh in itself if you want it to.
What can I say... I just don't like the C5. I like the '59B and similar A5 PAF-types even if they're scooped because they're always bright and aggressive in an almost twangy way, and they respond well to picking hard like I do. OTOH, I also like the JB because it's so focused and easy to fit in a mix and easy to play through. The C5 has none of those characteristics. It's scooped, and it's not dark, but the balance is more towards the lows than highs, and I've never liked bassy pickups. So if it's not open and airy like a PAF, I'd want it to be at least mix-read, but it isn't IMO because it's not focused like the JB. So, to me, it kind of sits in an uncofortable middle ground that I don't like. Where as the 498T is a more comfortable middle ground (to me) where it's focused like a JB, just not quite as much, so it retains a bit of that mid-output openness to the lows and highs.
JMO, of course. And then again, I left my 498T at Mexico. BTW, I don't know if all 498T's are like that, but mine had a roughcast magnet?
