This is the truth right here.
For example, to me, a stock Recto plugged straight in is nothing to get excited about, but *nothing* sounds like a boosted Recto with some bass cut at the input. No extra distortion stage needed, just more input volume and slightly cut input bass. Part of that sound includes “a cheap pedal” but there’s no other way to get that specific awesome sound, other amps won’t do it, those elements are just what it necessarily requires.
Might as well say “Do you know how much I paid for this amp? Why should I have to pay for pickups to put in this new guitar body blank too? My amp should sound good on its own without needing those other ‘cheap’ components.” Why? Because that’s just how that sound, which is the total of all the parts operating together, works… you bullheaded moron.
