The Maestro Fuzztain is a unique device that combines a CMOS compressor and an op amp drive with feedback clipping. The original version had three modes: clean compression, low-gain fuzz, and high-gain fuzz, which were controlled by a rotary that managed multiple parameters. However, a modified version was created to provide more control, separating the rotary into its individual controls. The compressor now has two level settings, and the fuzz has its own gain control. Additionally, the fuzz can be bypassed, allowing the compressor to function independently. The device is well-engineered in the style of 70’s Maestro, featuring a peak detector circuit that feeds the compressor and a capacitance multiplier in the PSU filtering section. The CD4007AE in the compressor may be slightly difficult to find, but it is not impossible.
