Hey guys...

Nearly got my rig sorted now, however I have just one more obsticle to get over...

My VH4 is really quiet now... only a tiny amount of hiss and hum in its base form (and thats when listening closely).

Only problem is that when I add a G-Force to the serial loop, even on unity gain, I find it introduces some hiss to the signal...

Someone suggested to me that it could be becuase the G-Force expects to be sending a balanced signal, but surely using an unablanced cable forces it to unbalanced which is what the VH4 expects?

What level does the VH4 effects loop run at? is it -10dBV?

Does the G-Force output at +4dBU?

If so, I was looking at this http://www.americanmusical.com/item--i-EBT-LLS2.html

This will convert the signals to the right levels and also convert the balanced signal to unbalanced and vice versa....

What do you think?

Thanks

Have u tried it on the parallel loop to see what happens?
 
Hi John...

No I haven't tried it in the parrallel loop as I've always wanted it in the serial loop to get the most out of it...

I'll try it though and set it to 100% wet and see if the noise still appears...

Thanks,

John
 
You could try making cables that have 2-core + shield (mic cable) and has:

Diezel End:
Mono jack with inside 2 conductors (Hot & cold)connected to tip and sleeve. Shield not connected.

G-force end:
Stereo Jack - 2 internal conductors (Hot and cold) connected to the Tip and Ring. Sleeve connected to shield.

Then the G-force provides the earthed shield, but the balanced outs runs to the diezel in's. That way there is no unbalanced signal ground connection between diezel and g-force, but the cable still has an earthed shield provided by the G-force to stop hum.

That's how my G-maj is wired (used the same cables I made up for my old rack pre-herbert). Never had any hum probs myself.
