Running an Extension Cab with a Blue or Pro Junior

johnhe · April 30th, 2006, 05:15 PM

There is no extension speaker connection on either amp. Is it possible to use some sort of y cable and run both an 8 ohm cab and the internal speaker or will this damage the amp?

Does anyone know if this appreciably increases the volume? I have a pretty large gig on Friday and am looking to beef up my sound if possible.

I think you just have to unplug the onboard speaker. That's what I always did at least. I don't think a y-cable would be a good idea.

Thanks 3string. did you play through a 1x12, 2x12 or 4x12? Did it appreciably increase the volume of your amp? I could borrow a 4x12.

I played thru a 4x10 bass cab actually, didn't have my 4x10 guitar cab with me at the time. I didn't notice that much of a volume increse altho I did notice better bottom end and breakup almost seemed tighter. I don't have my Pro Jr. anymore though. I did like the sound alot better then just thru the combo speaker. I'd say a 2x12 would open it up alot. I know there's more then a few on here that play champs thru a 2x12 in band settings and seem to get good volume if that's what you're looking for.
