The DT25 is the 25 Watt version of our flagship Double Trouble series amplifier circuit.  The Double Trouble is a faithful reproduction of the famous Dumble Overdrive Special amplifiers.  See the front panel detail shown below.  There are two identical inputs, a preamp control section, overdrive control section and power amp control section.  The Double Trouble circuit has four cascaded preamp gain stages.  The first two are used for the clean channel, and the second two are added when the overdrive channel is engaged, the clean channel gain stages feed into the Overdrive channel.  Three of the four gain stages have volume or drive controls on the front panel.  In addition there is a master volume control that sets the overall level of the amp.

The first Volume control in the preamp section sets the level of the clean channel.  The Bright switch adds a nice high end sparkle to the sound.  The Mid switch fattens up the midrange significantly, it adds a nice mid boost to the clean channel, and lot of harmonics and drive to the overdrive channel.  The Rock/Jazz switch adds a bit of extra midrange gain when set in Rock mode.  The Preamp tone controls can be used to set the balance of the sound based on volume level, room configuration, and guitar type.  They are not quite as active as some other guitar amps due to the fact that the preamp does not filter or "scoop" the mids.  This causes the Treble and Bass controls to have a slightly more subtle effect on the tone.  Set the Middle control at 2 or 3 to scoop the mids a bit, and the Treble and Bass controls will have more of an effect.

The Overdrive section has two controls.  The Drive control sets the amount of overdrive or distortion that will be introduced, and the Volume sets the level of the Overdrive channel.  Use the Overdrive Volume to match the volume level to the clean channel volume for a nice transition when switching between the two channels.
