The PRS “30” has an English sound with an American twist. Featuring a quartet of EL84 power tubes, this relatively low-wattage amp offers both vintage tones and modern versatility 
Every bit as musical as the guitar you plug into it, the PRS “30” could very well add another dimension to your playing and your tone. This amp operates on a “less is more” philosophy, with a cathode biased circuit and a simple layout. PRS’s transparent master volume feature disconnects the master volume from the circuit when turned all the way up for a more pure tone. Indeed all of these features help to create the “30’s” harmonically lush, ultra-responsive tone.
The “30” was designed to deliver an English sound with an American twist and can go from chimey, clean rhythm tones to semi-overdriven lead tones all with great body and bottom end. Engage the reverb and the tone of the amp fills out without overpowering the signal or drowning the notes. 

Features:
• Watts: 30
• Channels: Lead/Clean
• Power Tubes: EL84
• Preamp Tubes: (3) 12AX7, (2) 12AT7, (1) 12DW7

From Paul Reed Smith:

"A few years ago I was at the Dallas Vintage Guitar Show and 
my band was scheduled to perform a few times. A friend said, “Hey. You need an amp to play through, and I have a friend who makes great amps.” He took me to the booth of a Texas amp builder, Doug Sewell. I loved the way his amps sounded, and after barely saying hello, Doug and I were inside rewiring the amp I was going to play through. Since that day, Doug and I have spent years rewiring and listening to every single possible variation to finalize the circuits. Our goal was to have highly usable and musical amplifiers. 
I am not an amp collector. I am an amplifier user who keeps the amps I am presently playing through. That said, after Doug and I got several of the prototypes finalized, I sold some of my old coveted live and studio amps because ours sounded considerably better. The next step was to take the prototypes to musicians who are known for their amplifier tone as well as their playing. What’s interesting is that when I spoke to these artists about trying the amps, they all said the same thing. “Sure I’ll use them, if I love them.” 
In a real way, amplifiers are musical instruments. They are the devices that “amplify” the sound of the player’s hands, the guitar and possibly the pedal board. They must share many qualities. They must work - they have to have a beautiful balance of bass, midrange, and treble; the highs should be sweet - not harsh; they should be easy to operate and be highly musical. In addition, amps should clean up really well when you turn your guitar down. The final quality that Doug and I looked for are amps that sound good no matter where the knobs are. It is a rare quality that we insisted on. 
I hope this hand-crafted amplifier gives you years of enjoyment, musical results, and pride in ownership. I appreciate your confidence".
