Hi

A little while back I did some recording of Metallica riffs running through the V (AT7). Today I re-ran some of those tracks through the JP2C to A/B them. Both sound great, but the JP has a bit more thump and authority.

Mark V: has the Jan Philips AT7 tube in V4
JP2C Power amp: 60w
V Power amp (45w, variac, tube)
JP2C: Gain pushed
JP2C: Presence Pulled
JP2C: Shred not engaged
GEQ: Both On (Varied depending on song)
Cab: Mesa 2x12 Vertical Rectifier
Mic: Shure SM57
No post processing

I think I prefer the JP. Which do you prefer?

Hi,

Both sound great. I too preferred the JP-2C in your clip. Have you tried the Mark V in Mark iV mode? I find that the added pull deep that that mode offers gives the bottom end thump you want for the Metallica crunch. Gonna post up a pic in the Saturation mod thread in a bit of the settings i was using tonight to jam to some Metallica. Sounded pretty close to me with my EMG equipped Schecter. Give them a whirl and see what you think. Very low master volume so they probably wont translate well if you crank it but sounded great to me at the volume i was using.

Thanks,

Wayno

Hi Wayno

I love IV mode. You are right, it probably is closer to the JP and adds the thump but I find it can sound a little 'wet' sounding. To me it also has the most gain out of all the modes on the V and as it happens I try not to get used to it so I've got somewhere to go when I want more gain. It might sound stupid, but if I get used to it, would ruin the c+ mode for me. Likewise on the JP I keep the gain known pushed on Channel 2 so I can pull when I need more. This recording was with an Ibanez RG570 with EMG 81 in the bridge.

Very nice comparison which I just saw for the first time just now. Question: For the Mark V, why variac mode and why tube rectified? Wouldn’t normal power, even 90W (which is diode rect.) be a more apples to apples comparison?

Thank you, and funny you ask that now as I'm now experimenting with some of the other power settings. The variac / Triode is just a matter of preference. I like the liquid feel of the triode and find the pentode a bit stiff. I like the bounce character that is added in variac which initially I thought more closely matches the JP. I remember reading somewhere the original c+'s were wired in triode, but you are right.. a fairer comparison would've been through pentode non variac which is what I'm trying out at the moment. It's definitely a lot closer in tone, thump and power, especially in the IV mode.

That said, I recorded the DI tracks, so if you'd like to hear any other settings, happy to run through the amp.
