That clip makes me wish I had kept my Mark IV. Sounds awesome.
:shock:

You went in with casters on...?!?!?!? :shock:
Well done mate. Glad you had fun....!

iiC+ mode, neck pickup EMG 85 on my Schecter.

I did try the 12AT7 in that position a while back, not much of an effect really, just a reduction in gain was the result. It also happens to be the Reverb driver tube as well so there are some similarities to the V in that regard.

Great video. Was the singer the best man?

Yes, 3rd stage on the JP 2c. was where I was suggesting.
Try a Mesa 12AT7, might get a better effect for that position, I know It does on all three of my amps. But the Phase Inverter one likes other types. Pity if the sat mod doesnt work, cause I'd probably be up for a JP2c then... The reduction in gain also come with a revoicing at real high gain. Could be that your style of dialling might not need it/come across it.. or that your playing objectives don't require the sort of sound Im talking about... different strokes for different folks etc. 8)
Tungsols early in the chain are definitely great idea. The Goldpin ax7 is excellent for this application being the more noiseless of the goldpin vs silver.

The third gain stage on the JP-2C would be the same as the V5A circuit of the Mark V. The tube position with the 270k ohm plate resistor is V4 just like the Mark V amp. Now that the amp has some use on it, may try to tube roll and see what happens. I have not to that stage yet so I will chime in when I do. Curious if the 12AT7 in the PI of the JP darker. Amp is dark enough with stock tubes. Time to see what works and does not work.
