Members joemudge4 Posted September 1, 2009 Members Share Posted September 1, 2009 My first jmp was a '72 50 watter. I bought it from a guy listing it in the paper for $250, sold it about 4 years ago for $1700. It was prestine, I wish I still had it. The profit got me into my first ac30 though... so I don't know. I really enjoyed that amp too. Link to comment Share on other sites More sharing options...

What are the blackbacks? no different from gh12h/gh12m just with a different color sticker, same with the cream colored ones also do you always use the high right input? not a fan of the left?

Members telephant Posted September 1, 2009 Members Share Posted September 1, 2009 Since you're rocking single coils, get yourself a "y" cable and plug into the top two inputs and hear how {censored}ing massive your tele will sound. Glorious. Link to comment Share on other sites More sharing options...

Members telephant Posted September 1, 2009 Members Share Posted September 1, 2009 Is this different than jumpering the inputs? Yes! When you jumper the channels and use one of the low inputs it attenuates the signal a bit. If you a/b a patch cable with a "y" you can clearly hear the difference. When I had g12h30's I used to like the patch cable more, when I got greenbacks, I liked the "y" cable more. Although it could have just been my tastes changed.

Since I'm using the high input it's still plenty hot. I've never had much luck with Y cables. Link to comment Share on other sites More sharing options...

Members madryan Posted September 1, 2009 Members Share Posted September 1, 2009 my JMP > yours but for $700.... You're JMP gets points for being cameron modded but it's not a real JMP. It's essentially a JCM-800. Having owned both a 2204 and a NMV JMP I can say I like them both but I have to give the NMV JMP the nod when it comes to classic Marshall mojo.

Yeah that's what I'm talking about. One of the ends of the patch cable is in the low input on the bright side so you're getting some attenuation. With a "y" cable you're only blending the two high inputs of both channels. It does sound different but once you try both you may prefer the patch cable. Eric Johnson uses the "y" cable and one of my friends who used to do some teching for him turned me onto it. Link to comment Share on other sites More sharing options...

That's what normally jumping the channels looks like... :poke: Link to comment Share on other sites More sharing options...
