MB 210 with ext cab

ok so I just got my cab back today from Orange Sound in Western Mass. There wasnt anything wrong with it......so consider me and my friends idiots. But the guy is super awesome and really very nice.

So when I was playing today I had my vt bass going as a fuzz/od pedal and the mb210 shut off. the back of it was slightly warm. Im wondering how much I can give this thing in terms of fuzz, od, volume and what not before it shuts off and scares the crap out of me.

500 watts, between it and a GK 410MBE. 6x10's at 500w, seems like enough headroom so.....idk.

also the guy at orange sound used a 9v battery and an instrument cable to see if the cab was working, he just touched it to the battery and it made a popping noise. that was cool.

is the 410MBE an 8 ohm cab? If it isn't, your problem is running the amp @ 2.6 ohms. If it is, I'm stumped too.

True. My guess is that your 410 cab is 4 ohms. That could shut the amp off within a single song.

Also, I'm wondering whether the VT isn't sending too hot a signal to the instrument input of your amp. After all, it's VT preamp > amp preamp > amp power amp. That's a lot of "pre" before it hits the power amp stage. Maybe if you played with these three levels in an effort to minimize too hot a signal getting to the power amp... not sure. And I'm not sure it would shut the amp off. It might just sound distorted. But maybe the limiter would prevent that? I dunno.

I just got a SansAmp bass driver DI and I'm seriously thinking about running it directly into the effects return of my MB500 (pretty much the same amp you have, but yours doesn't have an effects loop) in order to avoid this. It will bypass the amps preamp stage (and the EQ!). But it might prevent clipping at higher volumes.
