I have been craving the feel and look of a Marshall JTM45 for awhile now. However, I have been using 18 watt amps so much lately for low stage volumes.... I'm not sure how much louder a JTM45 will be. The whole band is put through the PA night after night and the lead singer uses in-ear monitors for all live shows. Do you feel the JTM45 will sound good and tamed with a attenuater? I have never used a attenuater so I'm not really sure how it will work for a simple amp design like JTM. Any help on this amp with a attenuater is highly appreciated.
