Bogren Digital Ampknob BDM 75 (ESD); guitar amp simulation; based on a modified "Gold Face" amp from 1975 taken from the studio of a legendary but unnamed Swedish band; delivers an uncompressed, raw tone with a strong focus on crunch and distortion; features two separate preamp channels, with channel 2 offering an internal "Jumped" mode – virtually linking both channels in parallel, emulating the classic patch-cable method used on vintage tube amps to increase gain; includes two cabinet captures: Modern & Vintage - recorded at Fascination Street Studios; supports external impulse responses or disabling the internal cab section; IRDX technology models dynamic speaker behavior using machine learning; standalone version includes built-in riff recorder, metronome with time signature and tempo automation, and precision tuner; minimal user interface for focused workflow
