the reason i asked if having an archtop guitar vs flat top will make a difference in getting more squealing notes, is that I noticed in my les paul-like guitar, i can make em...weee! waaa! wuuuu! wooo!..there more squeling notes on it.
I'd flip the bridge pickup and vary my pick attack, make squeals near the bridge pu, middle, down to the neck pickup area...and consistent sya..With my ibby..I can make it easily squeal near the bridge, middle, but as i go down near the neck pu area, nde ganun ka-defined ung squeal...both on hi-gain settings naman...
BTW, i love those squeals i get near the neck pu..
I have this riff wherein my right hand wud jump back & forth for those notes, sarap.
