    Thanks for the help on the impedance issue....my rig sounds great! :D

    Now...there's the polarity switch on the back which seems to have three positions....is it okay to leave it in the neutral. center spot? I get no hum regardless of which spot but just thought I'd ask if there is a preferred setting if there are no hum issues.

    I'm going to be playing through a huge generator at an outdoor show today :cool:...I know I should have a conditioner but don't yet...any advice?

    Just read up on generators...skipping the SVT rig and going for my 4x10 and solid state head...I ain't taking no chances....

    I just got my SVT CL and have been just leaving it in the middle/neutral position. I don't think it matters unless there is hum, but I would like to know for sure also!

    Good call on NOT using the SVT with a generator...I know I wouldn't!

    oddly, most tube amps are more tolerant of goofy power than solid state...... but I can surely understand not wanting to play it in that situation ................in case of something truly obnoxious happening.

    It really depends on the type of generators, if it's the 8-15 HP ( 6000 watt tp 15000 watt ), the regulators are so...so, the sine wave when you look at it on a scope, has small pulses from the single cylinder engines and the Hz is always dancing around ... your bigger generators, the ones that are mounted on a trailer and diesel powered are a different story .... those have very good power, most of the times it's better than whats off of a pole/utility as a side-note check your grounds .... take a multi-meter and check the voltage .... me, I won't hook any of my equipment to the smaller generators, the larger generators 15 KVA and up you shouldn't have a problem
