Love my '57 Classic and Classic + ...and I've never played a Marshall amp.
I've tried a few in stores, and didn't care for the sound of them. Never bought one, never
borrowed one. *shrugs I really know nothing about Marshall amps, except that other guys
seem to like them. So I don't say much about them. If I was going to buy a new classic
tube amp, it would likely be a Fender Deluxe. I'm sure I can get great tone out of that, with
any of my guitars.
And I think Sergio's right... you can't make a meaningful general statement about any pickup
without also discussing what the signal chain is. I took the 490s out of my SG in like 2009 and
installed them in my Step daughter's Epiphone Les Paul Special ll, and they sound great in that'
guitar, played through her Fender G-DEC. --to my ear anyway, and hers. I think they sound better
in that inexpensive Les Paul than they did in my SG.
I didn't mind the 490s in the SG, only wished for more output from the bridge 490T. I used several different
amps (none of which were very expensive) and was able to get a usable tone in each case. Slightly different
sounding, but useable. I don't mind that either. I'm likely to explore the tone I find with any combination
rather than struggling to make it something that it's not. The 490s were noiseless as issued from the Gibson
factory, which is what we should expect. And my music is adaptable to many different tones. I only bought
the '57s because I wanted the best for my baby. I confess to being slightly obsessed with that one instrument.
And totally head over heels... arse over teakettle.
In my SG faded special, the '57s are brilliant, musical and excellent in all the frequencies... plenty of growl,
midrange is tough and present and sparkly jangly highs with no ice pick. That SG, with those pickups and
my Martin SixString wiring harness, played through my amps (especially my Vox VT-30 or my Orange Micro Terror)
is simply stunning. The best guitar I've ever played. My SG is dead silent, witn no need for shielding.
Go figure. I can't argue with Robert, because he knows his stuff. All I can say is: I'm happy with mine.
My other SG, the 2012 SG special with mini humbuckers, is also dead silent with no need for shielding.
That wiring is completely stock... because I like it so well.
My Vox VT-30 hisses a little, but it's not the guitar's fault. My Orange Micro Terror is pretty quiet.
And so is my Blackheart Little Giant. Those three amps give excellent tone with all of my instruments,
but especially with my favorite SG special.
So I'm happy to recommend the '57s without reservation.
