ok, i know its 300/100W in bi-amp mode, but how many will it be using with just one cab? i was thinking of a 2x10 and/or 1x12 later on. Also, im upgrading so i'll have something powerful enough for gigs, but im still gonna be playing with people at my house more than anywhere. i know its recemmended to have 4 times the wattage of the guitar, but i was just afraid 400W pushin 1 or 2 cabs might be a lil much for my house, especially when practicing alone. THANKS!
The amp puts out different wattage output at different ohm loads. The lower the load, the more power. I think you can go all the way down to 4 ohms, which is where it puts out the 300 watts. So if you get a 2x10" cab that is 4 ohms, the amp will produce close to 300 watts maximum. if the ohm load it 8 ohms, then it will be closer to 150 watts. If you have two 8 ohm cabs, then the 300 watts will be split between the two cabs evenly. As for your house practice, just turn it up as loud as you need it to be. It isn't like you have to use all the volume, or none of the power. Just dial in what sounds good. Wes
The 800RB actually does 200 watts at 8 ohms on the low side and 100 watts at 8 ohms on the high side. You can drive both channels in biamp or full range mode. Unless your guitar player is knocking walls down with his 100 watt marshall full stack, it should be fine.
