I was looking at the GFS site and notice the GFS Dream 180 humbucker. Does anyone have any wisdom about this pup's performance vs. the stock Gretschbuckers in my 5120?

completely different pickup than the gretchbucker ... Very nice, almost a little too hot, but very dynamic. I have a dream 90 in the neck position and the dream 180 at the bridge

How is the low-end response?

arent the dream 180s something akin to a powertron, sorta?

Not really like a PowerTron.

They are more like a dual-coil Dream90 (P90-esque).

I got the same setup, although I haven't changed the wiring because they sound great as is. Definitely better than stock.

I had them in an LP copy and thought they sounded great. I'm not a huge humbucker fan either. I'd buy those or the Crunchy PATs if I needed HBs again.
