Even IF Twinfan.....
Yes, guitar playing is not about how many knobs your amp has, but being too basical about it wont get you closer to the sound you are looking for in your head.
Kind off reminds me of that artsy fartsy stuff where less is more and such, maybe great stuff to get a painting done really fast, but this has nothing to do with music, the complexity of tone is something very different, knowing the amp you father had, you should know about this....... Those old fenders are among the most complex sounds in existance.
PS, ive tried My mules in two guitars and on several amps, they are very balanced eq wise, a bit middy maybe, but they are certainly not bottom heavy.
