With the rise of modelling amps trying to replicate vintage Fenders or classic Marshall and Vox amplifiers, preserving the originals is crucial. Modelling amps can't fully capture the upper mids, the sparkle or the “air” of a 1964 Deluxe Reverb or a 1970 JMP 50. On my YouTube channel, critics may condemn me for not replacing all coupling capacitors when one fails. I test components thoroughly for failures, out of spec, or imminent failure, unlike many critics who are either lazy, lack the proper equipment, or the knowledge of its limitations and find it easier to “shotgun” an amp. Goodbye vintage sound.
