Notadümblë V2

The JHS NOTADÜMBLË V2 is a dual-channel DIY overdrive and clean boost kit inspired by two classic Howard Dumble circuits. The overdrive channel is based on the modified Tube Screamer-style circuit associated with Dumble amplifiers, featuring Volume, Drive, EQ (low-pass filter), and Presence controls for medium- to high-gain overdrive. The clean channel recreates the A Box Later preamp/boost and includes Output and Input controls, the latter adjusting the circuit's input impedance to alter the tonal response rather than simply increasing gain. Both channels have independent footswitches and can be stacked in either order via an Order switch. A built-in TRS effects loop on the clean channel allows external pedals to be inserted into that signal path, making it possible to activate an entire effects chain with a single footswitch.
