The Thermionic Culture CULTURE VULTURE S15-B is the most comprehensive Vulture to date. It incorporates all the features found on the 11th Anniversary edition such as the 7 extra distortion functions, but also now features a 2 position Presence switch.
The Drive switch has three positions with a +10dB option sitting squarely between 'Normal' and 'Overdrive', enabling users to make their sounds 'a little more crunchy' with increased brightness.
The Function switch now offers further enhancements including special dynamic tunable mid-lift in the P positions and extra drastically-processed harmonics in the SQ positions.
The Output Level controls have a -10dB attenuator which can be used in conjunction with Drive+10dB for comparison purposes or just to reduce high levels.
The module's line inputs are balanced while the line plus low level outputs are unbalanced. The input valves are special quality M8100/5654 of Mullard origin and give low noise, more gain and long life. The dials now go up to 15 instead of 11!
