[About amp types]
THR’s GAIN t and MASTER y controls
work in the same way as the preamp and
master controls on a tube amp. The GAIN t
control provides preamp gain and distortion
while the MASTER y control affects power
amp level. The response of the MASTER y
control differs depending on the amp model
used but it affects volume, gain and power
amp compression.Using the GUITAR OUT-
PUT !3 control you can use the amp’s GAIN
t and MASTER y controls to set your tone
at any level.
THR utilizes a newly designed amp-modeling
technology using Yamaha’s Virtual Circuitry
Modeling (VCM) technology. VCM gives
THR the power to model real amps incred-
ibly accurately, with each control working
and responding exactly as it does on the real
thing.
