Basic Rundown of these 2 amplifiers in a high gain setting. Below is a reference of what inspired these amp models from positive grid
Positive Grid American High Gain Amp is available under the High Gain amp group and is inspired by the Mesa Boogie JP-2C Amp.
JP-2C John Petrucci Signature Head
The JP-2C was introduced in 2016. It is a 3-channel 100-watt "revival" of the Mesa Mark IIC+ designed in part with Dream Theater guitarist John Petrucci, who is well-known for using a Mark IIC+ in the studio. The three channels are based upon the original channels of the Mark IIC+, but with two high gain channels based on the IIC+'s lead channel. The second and third channels are very similar, with the third channel having a slight increase in gain. There is also a “Shred” setting, which further emphasizes upper harmonic content on the two lead channels. It also features two separate graphic EQs, which can be selected for each channel via mini toggles on each channel's front panel. It is also the first Mesa amp to feature MIDI connections, which can control the channel switching, as well as controlling the FX loop and graphic EQs. Much like the Mark 5:25, the JP-2C features a built-in CabClone. The amp also features a switch to drop the amp's wattage down to 60 watts for use in smaller venues or recording.
Insane 6508:
Positive Grid Insane 6508 Amp is available under the Metal amp group and is inspired by the Peavey 5150/6505 amp.
The Peavey 5150 is a vacuum tube based guitar amplifier made by Peavey Electronics from 1992 on. The amplifier was initially created as a signature model for Eddie Van Halen. After Van Halen and Peavey parted ways in 2004, the name was changed to Peavey 6505 in celebration of Peavey's 40th anniversary (1965-2005). The 5150 name was used again by Van Halen in partnership with Fender under the EVH brand in 2007 and 2011.[1]
Design of the amplifier began in 1990 and it became a flagship project for Peavey and for then lead engineer James Brown (who has since founded Amptweaker[2]), lasting for about 13 years, comprising the 5150 and 5150 II, until 2004. Peavey has since released several other versions of this amplifier.[3][4]
The 5150 has been widely used in metal and is renowned for its high gain distortion and character.
Conception
The 5150 was based on the Soldano SLO-100 which Eddie Van Halen was using at the time and designed to provide high gain saturation as well as a clean channel.[5]
While the product was designed around a centered printed circuit board (PCB), its cascading five preamps (actually four preamplifiers and one phase inverter) and four gain stages were implemented in a very simple manner. This design and implementation allowed the individual components to carry themselves (such as by placing the transformer so as to ensure acoustical integrity by minimizing transconductance), in addition to commonizing the system's ground by way of a multilayer PCB, thereby avoiding a large source of unwanted nuances in most poorly grounded musical applications.
Initially, the Peavey 5150 I shipped with four Sylvania 6L6 Power Tubes; this was later changed to Ruby Tube 6L6 Power Tubes, when Peavey's Sylvania supply was exhausted (per James Brown, "Tone-Talk", Ep. 17),[6] and five 12AX7 Tubes in the preamplifier staging (with one as a phase inverter).
A defining attribute largely responsible for the 5150 sound is the fixed bias. Commonly described as an analog to a car engine and its respective idle, the 5150 bias was set to a lower value (lower engine "idle") which resulted in the Power Tubes running at a lower energy commonly known as "cold-biased." This configuration supposedly resulted in a more controllable gain setting (i.e. having a more forgiving sonic range than similarly "hot-biased" configurations.
Use
Both the 5150 & 6505 are well known for their high gain overdrive channel, and have seen widespread use by rock, hardcore and metal guitarists. An early breakthrough was its use by Colin Richardson and Andy Sneap, two "seminal" British producers of heavy metal; especially Machine Head's Burn My Eyes (1994) helped the 5150 gain a reputation for its sound, which "defined a generation of guitar tone".[7] Other notable artists and producers to use the 5150/6505 include Jason Suecof, Matt Tuck and Dino Cazares.[7] Dave Hunter describes the 5150 lead channel as having "a harmonic bloom and juicy harmonic saturation".
Used in conjunction with an overdrive pedal (such as the Tube Screamer) to tighten the low end, the 5150 has been widely used in metal music.[9] The 5150 has gained popularity with extended range guitars (7, 8 or 9 strings guitars) because it retains clarity even with low tunings.[9]
