I've recently been perusing the Dumble type amp threads here on TGP and have seen a number of players mention that they prefer the 100 watt versions of these amps. The opinions are that the 100 watters have a bigger, richer sound at the same volume levels as their 50 watt counterparts. Does anybody find this to be true with the Fuchs ODS-50/ODS-100? I love my ODS-50 SLX, but I'm always up for bigger tone. Can the ODS-50 be upgraded to a 100 watts?
