Overview - Mesa/Boogie JP-2C Owner's Manual

Overview:

Much like a racecar or a fighter jet, the JP-2C strips it down to bare essentials to get the job done effectively, in the simplest way,
and get you from point A (inspiration) to Point B (or should we say "T" for Tone) in the fastest way possible. It's a purpose-built, no
compromises rendering that aims at one single goal; deliver the most aggressive, yet purest sounding II-C+ EVER in a package
that–while still extremely versatile–delivers the goods for John's Recording and Stage needs. All Things Heavy! But more specifi-
cally; the highest headroom Clean sound possible, a Crunch rhythm that has Lead Channel gain available, but is tight, grinding and
articulate, and the ultimate Boogie Lead Channel with even more saturation available and the ability to track any technique and speed
while also reaching to the stratosphere for single note solos.
In that spirit, unlike other MESA amplifiers, the JP-2C foregoes the concept of Mode Switching for the Channels and instead dedicates
each of the three Channels to one of these three musical styles and its requirements. The ONLY switch in each Channel controls the
status of Graphic Equalization for that Channel and the choice of which one of the two EQs on board will be applied.

CHANNEL 1
Channel 1 is dedicated to Clean sounds and is optimized for the maximum headroom possible in the preamp
section. Power section clip may be employed to attain some degree of overdrive in Channel 1, albeit at very high volumes due to
the 100 watt rating of the JP-2C power section. Additional "drive" may be sought in the upper region of the MID control (above 12:00
noon) as the MID pot employed here is the same value and taper as our MID/BOOST control found on some of our other amplifiers,
but the increased headroom in the preamp reduces the amount of overall drive available as compared to those amplifiers. This fact
renders this more powerful mid control as just that... a MID that has increased range and can add more midrange frequencies into
the mix with the other rotary Tone controls.
NOTE: For the MARK II-C+ Aficionado–Re: Channels 2 & 3; We have, in both Channels 2 and 3 of the JP-2C, removed the VOL-
UME 1 Control and the LEAD MASTER control from the Panel Layout as compared to the LEAD Mode of the original MARK II-C+
in favor of user simplicity. The LEAD MASTER is a largely redundant control here in the JP-2C–as it was in our MARK FIVE™–and
its setting has a very minimal role in the sound of the Mode (II-C+)/Channel (JP-2C), mostly affecting how much of the Pull BRIGHT
(hardwired ON here) is active and audible. The values chosen for its internal setting were arrived at through the same criteria we
always use; Tone and Performance
