Should I avoid using a 100 watt attenuator w/ a 20 watt amp?

    I'm looking for an attenuator for my 20 watt combo. Have a line on a used one rated at 100 watts. I've read you need to double the wattage of your amp when buying an attenuator. Does that mean I should go w/ a 50 watt attenuator or will the 100 watt one work just as well?

    Tnx.

    My Ultimate Attenuator can handle 200 watts and I've used it for my 18 watt Marshall and my Divided by 13 (switchable between 9 or 15 watts). No issues. Sounds great.

    Same with mine. I have a 200 watt Ultimate attenuator and I run it with my 67' 18 watt combo. I dont think I'll ever need a overdrive pedal ever again. Sweetest tone. I played with the band the other day and I got tons of compliments on my tone. Play it loud....But soft!

    No issues w/ using a 100 watt attenuator on a 20 watt amp. But you guys using a UA, better be setting your impedance switch to 16. Don't use that attenuator with 8 ohms or less.

    What kind of attenuator? When I use my Hot Plate on my AC30 it makes it muddy. High wattage resistive load attenuators just suck the life out of small wattage amps. A speaker cone driven one like a Weber or a load simulator mosfet one like a Ho/UA won't care tonally. All are safe to use.
