REISSUE Rumor: Mark IIC+ and 2ch Recto

[Doug Doppler]

Wanted to take a moment and wish everyone here a heartfelt HAPPY HOLIDAYS. This is a great community that I'm grateful to be a part of - thank YOU

I thought I remembered the reference on the JP2C in relation to the fixed resistors in place of the Volume 1 control. the channel mods the fixed resistor values in place of the Volume 1 pot, the pull on the gain also changes that as well. Been a while since I looked at the manual for the JP.

PULL GAIN This feature, along with the PULL voicing on the PRESENCE controls, was not on the original II-C+ amplifiers. We have added both in response to John’s questions and wish list of features. The PULL GAIN allows a slight BOOST… what amounts to a number more, on the (missing here) VOLUME 1 Control as it applied to the original MARK II-C+. Again, that control is preset internally after MUCH testing and consideration as to John’s requirements and our own feelings about the optimum setting of this sensitive part in the circuit. To describe what occurs in the pushed-in and pulled-out Modes in MARK II-C+ terms, it is basically like having two VOLUME 1 settings; In Channel 2–the slightly lower gain “Crunch Rhythm Channel”–that offers the un-activated, pushed-in setting of about 6.0 (or 1:00) and the activated PULL setting of 7 ¼ (or 2:15) or so. In Channel 3–the hotter “Lead Channel”–it shakes out like this; an un-activated, pushed-in setting of approximately 7 ½ (or 2:30) and the activated, PULL setting of 9.0 (or 4:00). The settings are referred to here as “approximately” or “about” because no two pots are ever exactly identical resistance-wise, and there is a fair amount of play in the older MARK II-C+ Pull Pots, so the number settings are general reference points and are approximate. The actual settings here in the JP-2C are achieved with a network of resistors per Mode (internally preset “missing” pot) with values that were arrived at through relentless scrutiny and are very precise.

The combination of the VOL1 control and Lead Drive control settings really depends on the guitar that you are using. That is why I like the original setup.
