Combo amp as extension cab?

[jmurphyguitar]

Hey All,
I have a fender blues deluxe and a mesa boogie subway rocket...can I unplug the speaker from the amp in the deluxe and send the boogie's signel to the fender speaker? I posted about this earlier but I am looking to get a little more low end and depth for my boogie and want to experiment with a 12 inch speaker extension cab before I go buying one.

Thanks for the help,

John

I do it all the time. You need a coupler to plug the speaker cable into. In the other end of the coupler you plug in a speaker cable which then plugs into the amp chassis where that amp's speaker cable would have gone. Make sure you have a good OHM match, but you can go up or down one level. I have a 4 ohm Champ 600 that I run into 8 ohm cabs, but I'm not sure if you can go the other way (8 ohm amp into a 4 ohm speaker, for example). Others with more knowledge will undoubtedly weight in on that. Also make sure the speaker can handle the other amps wattage.

I take a spare head with me to shows so if my covert fails I just plug into the head and keep on rockin

Thanks everyone...I think the fenders speaker should handle the mesa just fine then. The fender amp is 40 watts with a 12 inch speaker and the mesa is 20 watts with a 10 inch. Any one know what the ohms is for the fender?

The fender blues deluxe speaker is 8 ohms.

So on the back of the mesa there is a speaker plug that says 4 ohms...I can run that into the fender?

Why don't you just run both amps at the same time? Two different sounding combos going at the same time sounds really good, adds depth and helps eliminate dead spots on stage where you can't hear your amp well.

I have done that quite a bit but I love the mesa boogie so much more than the fender...also for my smaller venue gigs having both amps going makes things a little loud haha

I agree. I just got a Tonebone aby pedal...awesome. It doesn't need a power source and you get the tones of both amps which will enhance each other. I am running and Vox AC15c1 with a vintage National amp (1966). The pedal has a feature to throw the amps out of phase with each other (180 degrees switch) to round out your sound. WAY better than an extension cab IMHO.

Can that be a pain to mic both amps for the monitors? I have a feeling I would get all anal about how much of each amp I am getting through the monitors haha.

I regularly gig with two 1-12" 8 ohm combo amps. I use one as an extension cabinet hooked up by a connector and speaker cable as described above. I could run both amps, but don't really need the extra power and like to have the right-sized amp (my three combos are 8 watts, 18 watts and 35 watts). The two cabinets allows me to spread my sound out and get a little more apparent headroom. If I have a blown fuse or bad tube, I can always quickly switch to the other amp and get by for the rest of the evening.
