Power amplifier: the distortion generated by increasing the amplifier’s volume is quite
different. First of all, the distortion ratio is smaller, but it highly influences the harmonic
content of your tone. Without getting ino the science behind it, this type of distortion
produces a warm, creamy tone. It is generally referred to as ‘overdrive’. Second, this
distortion interacts with the volume, in a non-linear way: above a certain threshold (called
‘breakup’), the volume of the amplifier does not increase anymore ; only the distortion
increases. This allows you to play the ‘old-fashion’ way: you can control the overdrive
level simply by adjusting the volume on your guitar; or even by controlling the attack of
your pickup on your strings.
Power supply : many modern amplifiers -even tube-based- use a solid state rectifier for
the power supply. It’s cheap and compact, unlike the tube rectifiers found in pre-60s
amplifiers. The power supply itself does not generate any distortion per say, but it
influences the dynamics of your tone. An S.S.-rectified amplifier will sound stiff and
focused. A tube-rectified amplifier, on the other hand, will produce a slight compression,
or ‘sag’, which participates in the mellow, round tone of vintage-style tube amps.
6. Classic channel
The Classic channel offers the following controls:
[13] Boost
[14] Tone
[15] Volume
Tone settings
The tone control is very progressive and efficient. Its rather high roll-off frequency allows to
keep the excellent balance between bass and mediums which is so specific to this channel.
