Why We Love It: The Ultimate 100-Watt Compact Guitar Workstation
Inspired by Mesa Boogie's historic 40-year relationship with John Petrucci and their legendary collaboration on the JP-2C™ Head, this incredibly rare 1x12 combo version is part of an extremely limited run of only 100 units built worldwide. It packs all the headroom, immense horsepower, and burning analog tone of the fabled 100-watt Mark IIC+ circuit into a compact, 19-inch marine-grade Baltic Birch enclosure. It is the definition of a boutique "wolf in sheep's clothing."

Uncompromised Multi-Channel Circuit Engineering
Unlike standard tube amplifiers that use multiple voicing modes per channel, the JP-2C dedicates each of its three channels to one pure, specific voicing derived from the original, iconic Mark IIC+ architecture:
- Channel 1 (Dedicated Clean): Optimized for absolute maximum preamp headroom, providing sparkling, crystalline cleans that accept pedals beautifully. Pushing the integrated MID/BOOST control past 12 o'clock introduces a rich, clean variable gain boost.
- Channel 2 (The Crunch Generator): This is the pure, unadulterated Lead Channel from the original Mark IIC+ circuit. It acts as an aggressive, lightning-fast crunch rhythm generator that maintains note separation even at extreme high-gain saturation.
- Channel 3 (Soaring High-Gain Lead): Tuned with a slightly warmer, fatter, and compressed character specifically engineered for explosive attack and endless singing sustain during single-note solos.
Dual 5-Band Graphic EQs & Shred Voicing: The JP-2C features two completely independent, footswitchable 5-Band Graphic EQs. This allows you to assign a dedicated EQ curve to your rhythm tone on Channel 2 and a separate curve to your lead tone on Channel 3—a functional luxury that previously required touring artists to run two entirely separate vintage amplifiers via complex MIDI switchers. Both high-gain channels feature a SHRED Mode switch, adding a tight, three-dimensional harmonic sheen over your heavy rhythm tracking.
Advanced Silent Studio Integration: Built directly into the chassis is the industry-standard CabClone™ D.I. Cabinet Simulator and Internal Amp Load. This tool allows you to bypass your speaker entirely for silent recording or direct live mixing using Closed-Back, Open-Back, or Vintage cabinet emulations. The simulated stereo headphone output also captures the response of the entire tube power section for late-night session work.
Professional MIDI Control: A simple, one-touch STORE toggle switch maps your amp channels, graphic EQs, Shred modes, tube reverb, and the buffered effects loop to any of 256 MIDI program numbers, integrating seamlessly with complex pedalboards or studio systems.
