My thoughts would be a magnetic sound hole
pickup like the baggs m80 or a sunrise.
Although you can get a more natural tone
out of a soundboard transducer type like a kk
or jjb . the mag pups are more versatile and
will give a string response more in line with
what your used to (tele?). Plus when you
sell the blueridge and buy a martin you can
take the pickup with you.. ha lol..
There are many great preamps out there.
i've kinda settled on the grace design felix.
because i play mandolin and guitar in the band.
and it's two channels allow for different eq settings
for each instrument.
