The Electro-Harmonix Deluxe Bass Big Muff has features not offered on the original Bass Big Muff, including a pad on the input that is switchable between 0dB and -10dB, a Blend control to mix direct and distorted signals, XLR DI out, and a noise gate with adjustable threshold. Its footswitchable crossover has a variable low-pass filter on the dry signal and a variable high-pass on the distorted signal. Housed in a die-cast package, it uses a 9-volt battery or can be powered by 9.6-Volt/DC200mA AC adapter.
