Despite BOSS's longstanding expertise in crafting effective delay pedals, our engineers are always exploring new avenues. The DD-7 is a prime example of this, introducing a "Modulation Delay" mode and a modeling-based "Analog Delay" mode. Alongside notably extended delay times, it also features an optional expression pedal input for parameter control.
