Cascaded Linear Amplifiers

These fuzz types are composed of regular linear amplifiers chained together in series to produce hard clipping distorted output.

There is nothing unusual about the actual topology of the amplifiers. They can be analyzed as conventional voltage amplifiers.

This topology technically should include many 2 Stage Fuzz Blend designs, but that is notably different for the odd out-of-phase blending of the two stages instead of simply taking the final output. Also the shunt feedback clipping diode pedals usually cascade stages (Big Muff and clones, for examples); the difference is the inclusion of diodes for early clipping as opposed to leaving out the diodes and just relying on chain of transistor amps to drive the signal into the rails.

Examples:

Selmer Buzztone

WEM-Rush Pep Box (certain variations)

Maestro Fuzz Tone FZ-1S

Roland AF-100 Bee Baa

Nobels FU-Z Fuzz
