I dont know that i would categorically agree that the friedmans are heavy on the bass, as they are capable of being dialed in without that and a lot of high end.
That said, the phil X amp is definitely not a bass heavy amp - you could absolutely make that amp quite bright and abrassive on the high end, more than any other friedman (to me).
Its a very punchy, immediate, articulate amp - very jcm'ish but still with a dose of the friedman polish
