Yeah, I know about the linear notes. Thats where I got the information I posted on the last page. And yeah, Mike Ammot does use the JB/59 combo, I think he always has. As far as heartwork tone goes, they used a 5150 and a marshall 30th anniversary head to record the album if you're interested.
Just go for the warpigs man, you will not regret it. Loads of tight bass and mid range, perfect highs, chunky as $%, what more could you ask for in a heavy pick up?
