"A
great collaboration between Master Tele player Brad Paisley
and Master Amp Builder Dr. Z takes custom amps to a new level.
You get to reap the rewards!"
General
Info
The
original RX was always a controversial amp design with its highly
percussive response, “in your face” drive, immediate attack,
and high level of pinch note harmonics ( as demonstrated on "Dead
City" featuring Buddy Whittington.)
A collaboration between Master Tele Player Brad
Paisley, and Master Amp Builder Mike Zaite has given birth to the
all new Prescription Extra Strength. The new "RX
ES" is completely revised, from the input jacks to the output
jacks it shares no circuits with old RX.
The RX ES design structure is unique for a DR.Z
Amp, it uses an EF -86 pentode set up in a post EQ gain layout.
This alignment yields a rich harmonic complexity and an almost active
response from the tone stack. Its dual calibrated inputs allow for
sustaining gain in the Hi input, and a rich warm clean in the Lo
input jack. The RX ES also features a footswitchable "Overdose"
mode, which engages a 3 dB boost for added drive and gain without
altering the preset tone, same EQ'd tone just much more DRIVE.

DR.Z's old friend and avid supporter of DR.Z Amps
since 1989, Joe Walsh demo'd the RX ES and ordered one on the spot
to use on the Eagles Oct '04 tour of Japan. Look and listen to his
Blonde RX ES on new Eagles' releases, and upcoming shows.
NOW AVAILABLE!!!!
The Prescription Junior Strength (Rx Jr.) The Rx Jr has all the
same sonic characteristics of the ES, but at half the power. The
Rx Jr features a post phase inverter master volume, 3 dB footswitchable
boost, EF86 post EQ gain layout, a pair of cathode biased EL84s,
and a 5Y3 rectifier. The post phase inverter master volume let's
you maintain all the integrity of your tone with the ability to
control the overall output. The 5Y3 rectifier gives a sweet bloom
to the low end. When you don't need a full dose...the Rx Jr is just
what the Dr. ordered.
The RX ES uses
two 12AX7 tubes in position VI and V3.
In the center
of the RX ES design is an EF-86 pentode gain stage in position V2.
The EF-86 has
an increased bandwidth and double the output gain of a typical 12AX7.
The Overdose
gain boost is connected to this stage, engaging this boost is likened
to engaging the best OD pedal.
The output tubes
are Groove Tube EL-84-S (Tesla variant), matched and balanced using
a rating number of 6.
Finally, the
RX ES uses a 5AR4 rectifier in it's power supply. Giving the over
all amp a slight sag, the 5AR4 adds bloom and natural compression
to each note.

Sound
Clips
Usually
the sound clips are the last thing to make the website. This time,
it happened all in reverse. Brad Paisley was in
discussions with us about the creation of a new amp, and Brad and
crew stopped by the shop to put the final tweaks and finishing touches
to the amp. The amp is based on the Prescription, but with a new
vibe. The amp has been described as a cross between an AC-30 and
a Dumble. Brad mic'd it up right there in the workshop and gave
everyone a chance to hear it "at birth." The was dubbed
the "Prescription Extra Strength" and Brad graciously
left us a 3 1/2 minute demo of the amp before he drove away.
So...enjoy the MP3 of the Prescription
Extra Strength, just minutes after the design was tweaked and the
amp was finished. The Sound File is with the other s below..
