Independent shopping perspective
The Korena take
The JMX100 is BC Audio’s 100W tube guitar amp head in the Octal-Plex series. Its Superlead circuit uses 6SL7GT octal preamp tubes, four EL34 power tubes, and silicon diode rectification. BC Audio describes the series as based on Marshall plexi circuits adapted for octal preamp tubes, with a point-to-point handcrafted build. The model is presented for high power and headroom, aggressive crunch, singing leads, and substantial low end, with optional footswitch-controlled gain and volume boosts.
