Head & Cab

[Superfly]

Hey guys here's my Dilemma..
I am buying JGs 4x12 cab. The details are this,
The cabinet is currently wired in true 8 ohm stereo with 2 jacks on the back of the cabinet. Each set of speakers is wired to its seperate output jack which is 8 ohms. I can also wire it 16 ohms mono if you prefer.
I also bought Toes Fender Roc Pro 1000.
My question is should i or rather can i leave the wiring for the cab as is or switch it to 16ohm mono.
Toe said that it has 2 speaker plugins so i COULD technically plug them both in that way but only 1 side is 8ohm. The other is 4ohm.
Sorry for the potentially stupid question, i have always been a combo guy. I guess if i dont ask this stuff i will never learn right?
Thanks in advance...

Actually, I think the 8 ohm is automatically switched to 4 ohm when using both inputs together (I think the manual or maybe even the back of the amp has a detail about this; don't recall as it's on its way to you [img]/images/graemlins/cool.gif[/img]). When using two 8-ohm cabs together, it puts the ohms down to 4. I'm not sure about the stereo cab, but if it's truly putting out 8 ohms per side from each jack on the cab, then I think you should be okay. Or you can probably just use one output from the cab into the 8-ohm of the head (though I don't know if all speakers will be on or just one pair). Hopefully someone else can chime in to help.

Re: Head & Cab

Toe is correct. If you use both jacks they will both be 4 ohms. Since my cabinet has 2 8 ohm jacks you will be fine.
Toejam.. my 4 x 12 has 25w Peavey scorpions in it. They are 4 ohm speakers. I have them wired:
Left top and bottom ----- 8 ohms
Right top and bottom ---- 8 ohms

Superfly should be fine. If the Rocpro is looking for a 4 ohm load from each jack and we feed it with an 8 ohm load into each jack the amp will be happy.

I've also got a RocPro1K head and I love it - congrats [img]/images/graemlins/toast.gif[/img]
If you get a chance, run the RP's preamp through a tube power amp - it gets REALLY good then [img]/images/graemlins/grin.gif[/img]
