The ""JR BARNYARD Pre-War Hot Preamp"" (1930's-40s octal tube amp character pedal). Inspired by Nocturne Brain's ""Moonshine'39" amp a repro of the 1939 Gibson EH-150 /185 pre war tweed amp and its octal tubes. I've created a textured hot club style preamp to garner those early Charlie Christian flutey reedy amp tones to Texas Playboys Junior Barnard and Eldon Shamblin dirty octal tube swingin' Texas blues.
With so many players gravitating toward easily mobilized rigs, be they compact nice solid state amps like Quilter, Milkman,etc or direct to house units (FRFR) like the Strymon Iridium, helix stomp,etc w IR (impulse response) tech, the player can feel removed from the tactile response they've grown accustom to w a tube amp's dynamic interaction and interplay between clean and "edge-of-breakup" w the guitarists fingers and speaker. Even more so with roots musicians who crave that tweed response, or even further back with octal tube amps reedy bark.
