The Sunn Mod 60 is a 60-watt hybrid amplifier combining a solid-state preamp section with EL34 output tubes, offering a compromise between the maintenance simplicity of solid-state and the harmonic character of valve output stages. The 60-watt power level places the amp in a practical range for club and studio work, and the EL34 output stage introduces the natural compression and harmonic richness associated with tube amplification while the solid-state preamp provides consistency and low noise. The Mod 60 reflects the industry-wide experimentation with hybrid designs that characterised the mid-to-late 1970s.
