The Tiny Terror has a great reputation for it's tone.  It's an interesting design which doesn't follow the usual Fender/Marshall designs but is more like (very like in some parts) a VOX AC15.

 

It is a cathode biased push-pull amp which is fairly unusual as most are fixed bias.  This gives it a really warm, thick tone.  Probably the most famous amps that are ALWAYS cathode biased are Matchless. Like the VOX, there is some debate over whether it is in fact a class A amp or not.

 

It sounds great when driven hard but unless they are able to play the amp at high volume most owners will never hear it because it's very LOUD.

 

In its standard form it has a power switch that lowers the amp voltages - NOT a triode/pentode switch as some people say.  This works to lower the volume to some extent but half power is NOT half volume.  To halve the volume you need 1/10th of the power.

 

The amp works very well with Power Scaling™ and being cathode biased it costs a lot less to scale than a fixed bias amp.

 

From the factory the valves are biased at a very high idle level which shortens the valve life and - in my opinion - does not sound as good as when they are biased to a lower setting which we do as part of the Power Scaling™ installation.

 

To keep it looking nice we fit a new combined mains/standby switch and replace the Power control with the Power Scaling™ control with a matching Orange control knob.
