VALVE REACTOR TECHNOLOGY
THE POWER (AMP) AND THE GLORY!
alve Reactor technology was first used on the critically acclaimed VOX
AD60/120VT Valvetronix amps.
The Valve Reactor circuitry in ToneLabSE however has been tuned-up
especially for live performance.
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 imped-
ance that are created by the power amp driving the speakers. ToneLabSE con-
tains an actual low-wattage valve power amp circuit, a virtual output transformer
(patent applied for) that uses solid-state components to simulate an output trans-
former, and a dummy speaker circuit that simulates the varying impedance of a
real speaker. This means that although it’s low-power, ToneLabSE has the same
circuit structure of an actual all-valve amp.
While much of the tone creation and shaping carried out is done in the digital
domain, its Valve Reactor power amp is 100% analogue. The resulting journey your
guitar’s signal takes through the analogue world of the power stage plays a major
role in providing the all-important feel and tone of the original amps we modelled.
The Valve Reactor power stage is, to all intents and purposes, a bona fide valve
(tube) push-pull power amplifier, but in miniature. It utilizes a 12AX7 (ECC83) valve
(a dual triode device - meaning “two valves in one”) and is equipped with an output
transformer, like a “real” valve amp.
The power amp output of ToneLabSE’s Valve Reactor is designed to “read” the con-
stantly changing impedance curve of the dummy speaker circuit system and feed this
information back to the virtual output transformer – just like real valve amplifiers do.
This information permits the behavior of the valve stage of the amp to vary with the
speaker load (impedance), which is another important part of “real world” valve tone.
