Our Blues Junior "Deluxe" is an awesome blues and rock amp that will get the job done on stage and in the studio. You can go from Princton Reverb tone to singing bluesy sustain in one amp and control it with your guitar volume.

It is a 20+ watt, 6V6GT based tone monster, and the results are so good that it's kind of silly!

We upgrade the output transformer to a wide bandwidth, high fidelity transformer. Increase the power supply capacitance considerably which along with the new output transformer, helps the amp deliver greatly enhanced bass performance. During the redesign, all plate load, cathode and grid resistors are replaced with good quality carbon composition parts. Bypass caps, coupling caps, tone stack parameters and the phase inverter improvements are all part of the recipe.

Stock Jr's are notorious for oscillation problems in the long tailed pair phase inverter. We rewire the circuit to utilize a cathodyne inverter. This is same circuit you hear in a Princeton Reverb and Deluxe. This offers an entirely different feel to the amplifier. Because of the different approach in Phase inverters, our Deluxe rendition uses 4 amplification stages all properly set up and tweaked for tonal nuances from stage to stage which delivers wonderful responsiveness and tonal versatility in the amp. Shimmering clean tones, warm jazz tones and singing sustain can be rolled in and out of with your guitars volume control.

We maintained the use of the foot switchable "Fat" switch, but the effect is quite different. It is a very usable lead boost. It increases the overall volume of the amp just enough, but takes the drive tone of the amp and just nails it. It adds just the right amount of compression and sustain, but doesn't muddy or drastically change the tone of the amp.

The amp uses 3 12AX7 preamp tubes, but the power amp is converted to the venerable 6V6GT. The new 8 pin ceramic tube sockets are mounted directly to the chassis.

We install a 12 inch 16 ohm American made WGS (warehouse guitar speaker) veteran 30 driver We use 16 ohm loads whenever possible because the damping factor is higher, which simply means that the amplifier has more control over the speakers moving parts which translates into better low end performance.

There is a true external speaker jack installed on the amplifier that disconnects the internal speaker when used.

We install a standby switch right above the indicator light.

The stock reverb performance in improved greatly due to the significant changes made in the beginning of the signal path in the amplifier. The signal driving the reverb is improved and the return signal is improved and as a result the reverb sounds better and is also foot switchable! You can toggle your reverb on and off by the 2nd included foot switch.
