BJF Dyna Red Distortion is one of the finest Marshall Plexi/JTM45-style overdrives ever made. Björn Juhl did a limited special edition for Custom Sounds which is better than the previous versions and works better with different amps. Pedal designer and maker Björn Juhl describes the DRD 2024: "This is latest development with twice the gain and in accordance with feedback given over 20 years in terms of prefered frequency response with full body and a tad less aggressive upper mids to ensure better control over treble.".
