Just picked up a used Ghia and have been reading here on the boards about tubes, speakers, etc.
My question is regarding mismatching the load. I read where Z says that it's ok to mismatch one step either way with the Ghia. I remember him telling me it wasn't ok to run an 8 ohm load in the 4 ohm tap on the Maz Jr, but he didn't elaborate as to why and I wonder why it's ok with the Ghia. I also understand his favorite setup is a 4 ohm cab in the 8 ohm tap with the Ghia, saying that this allows for earlier breakup. I find this confusing since it seems that a higher load should create earlier breakup rather than a lower load. I would think that a 16 ohm load in the 8 ohm tap would reduce the volume and cause it to break up early. Can someone explain this for me?
Thanks for the very informative posts, by the way!

The lower the speaker load then the higher the current drawn from the output tranny which allows the amp to drive harder and break up? I used a Boogie for years and the manual encouraged experimenting with speaker mismatch but I never liked the effect - just a harsher distortion to my ears.

I used a Boogie for years and the manual encouraged experimenting with speaker mismatch but I never liked the effect - just a harsher distortion to my ears. Ok, that makes sense. It's strange that I really preferred my Maz 18 with an 8 ohm load in the 4 ohm tap...did it by accident a couple of times when I left the extension cab home and those nights were the best that amp ever sounded....so I was pretty disappointed when I asked Z if it was OK and he said, and I quote his entire response, "No"! So I'm left not really understanding why, but I guess if anybody knows it is he, so I didn't question his reasoning. I'm happy to hear that it's ok to experiment with the Ghia! I played around with mismatching with my old Mark IIB quite a bit and also found that I preferred it matched up. Thanks for the info!

If you like an amp's sound when it's driven hard keep this in mind. An amp always sounds best when it's about to BLOW.
