HE OWER AMP AND THE LORY
The Valve Reactor circuitry in the SV-1 has been tuned-up especially for live perfor-
mance. Since conventional modeling effects for line recording are not used directly
with a speaker, they do not include a power amp circuit, output transformer, or
speaker. In other words, they only have a preamp circuit.
A real valve amp sound, however, is produced not just by the preamp, but also by the
tone and distortion of the power amp, and by the constant changes in impedance that
are created by the power amp driving the speakers. The SV-1 contains an actual low-
wattage valve power amp circuit, a virtual output transformer that uses solid-state
components to simulate an output transformer, and a dummy speaker circuit that sim-
ulates the varying impedance of a real speaker. This means that although it's low-
power, the SV-1 has the same circuit structure of an actual all-valve amp.
This is great when playing live, because the sound arriving to the main mixer is the
same of a real analogue amp captured by high-quality mics.
