Jack of Rocknroll Amps is our amp tech at South Shore Guitar Boutique. He has a long history building and servicing high-end Boutique and Vintage amps. While not concerned with trends; Jack builds his amps the old fashioned way inside and out. Each amplifier is hand fabricated and meticulously hand wired with only the highest end components and speakers. They are true tone machines. If players in the 60's had any of his models, it would have been used as their secret weapon. The Douplex is a 10 Watt 2 EL84 Tube Combo Amp. You can go from Bassman to Plexi and at any volume you'd like with the intuitive master volume circuit that preserves your tone. For those who prefer demonstrational videos, Jack has made a great demo with all of the features this great combo amp has to offer. You can find the video link in this listing.

The Duoplex EL84

3 modes of operation

1)- Both volume pots pushed in and both toggle
switches UP, gives 2 channel Clean mode using Fat volume and Plexi
volume. In this setting it is like a 59 Bassman . The two channels are
internally jumper-ed and are blend-able. In this mode the Plexi cap is off
rendering the Plexi channel to be a brighter brother to the Fat channel and not
Plexified.

Try the 2 channels individually. Tone control
changes should be made to either add brightness to the Fat channel, or control
the brightness of the Plexi channel. Don't forget about the presence control.
In this mode I don't recommend using the resonance control because the Fat
channel is fat enough. But, hey, your ears may like it.

Try bringing up the Plexi channel to a reasonable
volume and then slowly add the Fat channel adjusting tone controls and presence
to taste. Plug your pedal board in and rock on.

2)- Real Plexi mode can be achieved by
making sure both toggle switches are up. Pull the Plexi pot up to engage the switch. Start with the Plexi volume
on zero. While some of you out there might enjoy the extreme treble I recommend
rolling the treble and presence way down. You can always add more. Adjust the
Fat volume to taste and slowly roll up the Plexi volume control until you find "the spot". From there you can make whatever changes you'd like to. Treble, middle,
bass, presence. Try using the Resonance control here.

3)-2203/JCM800 mode is achieved by making
sure both volume pots are in the down position and on zero. Both toggle
switches should be placed in the Down position. In this mode the Plexi volume
control now becomes Gain. The Fat volume control becomes the Master volume.
This mode works well with Resonance. You can go from mild distortion to nice
crunchy thick overdrive. The Master volume pot can be pulled up for more treble
but I would recommend dropping the treble and the presence control when
engaging this Bright switch. In the history of the 2203/JCM800 there is a
treble "peaking" circuit that many people chose to remove. Here it is
on a switch. While I find there is enough gain, if you need higher gain you can
always put a distortion pedal in front of the amp.

A) Slope Resistor switch. The value of the slope
resistor, controls how frequencies are
divided over each tone control. The
slope resistor changes the slope of the mid-range dip. The difference is subtle
but there. Slope Resitor switch is on the inside of the cabinet. The up
position is a 59k slope resistor. The down position is a 47k slope resistor.
The tone controls will respond a bit differently.
