Mad Professor Deep Blue Delay Handwired
Delay
The Mad Professor Deep Blue Delay Handwired is a Finland-built digital delay with an analog dry path and top-mounted jacks.
Level, Delay, and Repeat control echo level, a 25–450 ms time range, and feedback, with filtered echoes recalling vintage tape and analog delays.
Place it before or after distortion or in an amp loop to add short echoes or decaying repeats alongside the dry sound.
