Neural DSP has revolutionized the world of guitar recording. Their algorithms are widely considered the gold standard for digital amp modeling, capturing the "feel" of a real tube amp better than almost anyone else. However, at roughly $100 to $150 per suite, they are a significant investment.
Go to the Neural DSP website and select a plugin (e.g., Archetype: Petrucci or Archetype: Gojira ).
It is open-source and has a massive community on ToneHunt.org where you can download "profiles" of real Boutique amps for free.
