Re: Potential replacement for SH-5
Get an Alnico 3 RC magnet in there. Trust me, it makes the Custom godlike!
I tired, Custom, Custom 5, Custom 2, Custom 5 UO&RC (this one is second best), Custom 4 and finally Custom 3 - haven\t looked back since the Custom 3.
I've never tried a RCA3 in a SH-5 (Custom 5). But I use the RCA3 in my 59N and Antiquity N neck humbuckers. Great for clean chords and for soloing.
In the bridge humbuckers I use (59B or Antiquity B) I didn't like RCA3 or RCA4 either.
Just doesn't push my amp hard enough. A little too polite. Couldn't get the Clapton w/Cream and Eric Johnson violin tones I like.
But the Custom is a different pickup with more turns of copper so I don't know how RCA3 would sound in that.
I had a Strat that I tried the Custom (ceramic), Custom Custom (A2) and Custom 5 (A5) in.
All three are the same pickup with different magnets but I didn't swap magnets back then. I actually tried three different pickups.
I found the Custom 5 to be midrange scooped and overly edgey or sharp. Not the kind of tone I feel comfortable with.
The Custom Custom was just the opposite and pretty cool! Less bass, less treble and more mids with kind of compressed but chewy feel. Kind of like chewing on a squishy caramel. I liked it but not enough to keep it.
The Custom I liked best of all but it does have that "ceramic" sound. Not as organic or squishy as I like but I found it to be the most usable of the three.
I'm not really a fan of HOT humbuckers. 59's, Seth Lovers and Antiquitys are what I've settled on. But I do swap magnets. RCA3 or RCA2 in the neck and RCA2 in the bridge.
I'd rather set my amp up for clean tones and then use an overdrive pedal for those sweet violin-like tones I prefer.
