About the amp models and effect types

This section provides details on the amp models, the various types of
PEDAL1, PEDAL2 and REVERB effects as well as noise reduction.
Unnatural distortion may occur, depending on the amplifier and
effector settings. If this occurs, adjust the amp and effect parameters.
If a parameter not available on the top panel is changed in the
Editor/Librarian software, the tone may become quite different from
the original amp model or effect type.

1 . DELUXE CL
This dual channel, 22W blackface 60's design used 6V6 power tubes and
a tube-driven spring reverb to produce a big sound at a lower wattage.
Our modeling is based on the Vibrato channel of this amp.
2 . TWEED 4x10
This models a 4x10" combo amp from 1959 that was originally designed
for bass guitar. Its smooth and crisp overdrive sound will respond
sensitively to your picking dynamics and to the volume of your guitar.
3 . VOX AC30
This models the Normal channel of the AC30.
The clear high range of the Celestion alnico "Blue" speaker, as well as
the rich midrange, deliver a captivating clean sound.
4 . BOUTIQUE OD (BTQ OD)
This models the overdrive channel of a high-quality amp that was known as the
Overdrive Special, which was produced only by special order. The wonderful
sustain obtained by raising the GAIN control is smooth and soulful.
