I bought a Maz Jr. 1x12 combo 6 or so years ago (before there were any dealers here in Los Angeles) new from Chapin Guitars (they used to sell select amps). It came with a 16 ohm Greenback yet the speaker output on the amp is labeled 8ohms. I used the combo with the original speaker for quite some time but eventually replaced it with an 8 ohm Greenback. Now I am considering getting a 1x12 extension cabinet for the combo and was wondering what to do about the load.
My general question is how tolerant of mismatched loads is the Maz Jr? Can I safely use the combo with 4 ohm or 16 ohm loads?
More specifically, I plan to use the combo sometimes with and sometimes without the extension cabinet, so what would be a better configuration: (1) leave the 8ohm Greenback in the combo and get an 8ohm ext cab (2) put the 16 ohm Greenback back in the combo and get a 16 ohm ext cab

I personally would not mess around with mismatched speakers. Even thought the general rule is you can have more speaker resistance than the output jack calls for. Of the two options you listed, either one will work. You will however, need to get a small splitter box to plug both the speakers into. As far as I know, you can only have ONE speaker jack plugged in.
For example:
Speaker cable plugged into 4 ohm jack on amp end, splitter box on other. Then from the splitter box, two cables out...one to each 8 ohm speaker.
(You may also need a male to male adaptor to hook up the speaker in the combo.)

Thanks for your reply. I also sent this question in to DR Z. The response I got (I'm paraphrasing) was:
1. definitly do not run two 8 ohm speakers in parallel as a 4 ohm load will damage the output transformer.
2. it is safe to run a 16 ohm load to the 8 ohm tap on the output transformer.
So the better option for me will be to put the 16 ohm speaker in the combo and get a 16 ohm ext cab.

Are you sure you paraphrased that correctly?
Two 8 ohm speakers, wired in parallel will be 4 ohms. As long as your amp has a 4 ohm speaker jack, you'll be fine. My Maz Jr has a 4 ohm jack.

I think the Ghia is only 8 or 16 ohms.

Yes, I paraphrased correctly. The response pertained to my Maz Jr 1x12 combo which has a single 8 ohm jack.

My question is are you forcing a square peg into a round hole? Will the end result be a better sound? How about a 2-12 or 4-10 cab plugged in bypassing combo speaker...I'm doing that now with my Maz...whole different set of tones.

AH!!!
I didn't know your amp only had an 8 ohm jack. My Maz Jr has both a 4 and 8 ohm. Then yes, you have to go the 16 ohm speaker path you mentioned.

Pro Cables and Sound makes a speaker splitting cable for us for this purpose thanks to Jason G.
He even offers us here a discount if you order it correctly.

Ditto the Pro Cables N sound parallel cable, gotta give them prop's. I run it with my maz jr into two 8 ohm speakers plugged into the 4ohm jack on the amp. Opens up a new world.
