Academy of Tone #305: Friedman Jose Arredondo 100W – Why Guitar Heroes Needed Modding

This episode is not only about reviewing an amp. It’s about the idea behind it. Dave Friedman carries forward the legacy of Jose Arredondo’s groundbreaking amp modifications with the Friedman Jose Arredondo 100W—a faithful tribute to one of the most influential modders in guitar history. “Passion for the tone” has always driven guitar players further than any stock amp could go. The sounds we associate with guitar heroes didn’t come from standard circuits—they came from the need for more. More gain, more sustain, more expression. Without modding, those tones wouldn’t exist. And without great players, modding wouldn’t matter. Jose Arredondo understood that early on. By modifying Marshall amps for the guitar heroes of the late ’70s and ’80s, he helped ignite the high-gain revolution—and shaped the sound of a generation. Artists like Eddie Van Halen, Steve Vai, James Hetfield, John Sykes, George Lynch, Yngwie Malmsteen, and Jake E. Lee weren’t just playing amps—they were pushing them beyond their limits. Thomas connects to this on a personal level. Wanting to reach that “guitar hero” sound himself, he started modifying amps early on—driven by the same belief: that great tone doesn’t just happen, it’s built. In an exclusive conversation, Thomas talks with Dave Friedman about this shared mindset, the legacy of Jose-style mods, and why this approach to tone still matters today. A sound shaped by players. A legacy shaped by modding. #AcademyOfTone #FriedmanAmps #JoseArredondo #GuitarTone #HighGain #MarshallMods ____________________________________________________________________________________ Get your AMP1 MERCURY EDITION and IRIDIUM EDITION with 3 YEARS WARRANTY and FREE SHIPPING (within EU): https://bluguitar.com/en/products/ ____________________________________________________________________________________ https://bluguitar.com/ 0:00 Intro 5:44 Welcome & Episode Overview 6:57 Amp Modding Importance 7:21 80s Guitar Heroes 8:23 Plexi Marshall Roots 9:30 José Arredondo Story 10:00 Amp Walkthrough Begins 11:00 Plexi Mode Explained 12:36 Boost Stage Demo 14:37 Clipping Switch Explained 16:57 Tone Controls Overview 19:29 Dual Master Volumes 21:09 Effects Loop Demo 23:08 Plexi vs José Amp 25:00 Vintage Amp Demo 27:04 Stock to Modified 29:25 Guitar Hero Gain 31:11 Gain Evolution Steps 33:31 Tribute to Modding 36:37 Interview Starts 38:30 Dave's Early Influences 43:28 José's Workshop Story 50:00 Eddie Van Halen Sound 57:32 Modellers vs Real Amps 1:00:30 Keeping Guitar Alive 1:04:30 José Mods Breakdown 1:16:16 Amp Modding Legacy 1:27:26 Clean Tones & Digital 1:37:05 Dialing By Ear
