Head/Cab Question


Recommended Posts

OK... My confusion is basically over what cabs go with what heads.


The Valve Jr. head has 4, 8, and 16 ohm outputs. So, this means that I can hook up a single cab that has no less than 4 ohms impedance, right? But what do I do if I want to use multiple cabs?



The reason I bring it up, is I was checking out the difference between the Blackheart Little Giant and the Valv Jr. The BH amp, has five outputs: 4 ohm x2, 8 ohm x2, 16 ohm x1. The manual said that if I wanted to hook up two 8 ohm cabs to use the 4 ohm outputs. Similarly, if I wanted to hook up two 16 ohm cabs, I should use the 8 ohm outputs.


Does this imply that you can't use the VJ in a parallel configuration?


I'm a total noob at the head/cab thing, and physics class was 12 years ago!

You could add output jacks very simply. However, here is the solution I use, it is very easy and only cost me a dollar.




I got the jack plate from PartsExpress. I'm using two 8ohm speakers. When using a single cabinet they are always 8ohms. Right now, if you daisy chain a cab out they are in parallel, so they use the 4ohm impedance. But, I could just as easily wire them in series for 16. If I used two 16ohm speakers in parallel I'd use the 8ohm jack on the VJr. I have an Eminence hemp cone Lil' Buddy in the top cab, very smooth. The bottom is an AlNiCo blackframe from some kind of a Fender reissue. Great speakers, that really compliment each other.




I think it's a nice rig.
