I currently own and use a RM50B combo in a cover band. I have an older model with the older logo and one that is less than a year old. Even using the exact same tubes/modules and tube bias settings, the older one is more powerful and cleaner....I have tried everything to make sure that both are tested w/the same components (tubes/modules) and I am wandering if the older ones were made differently and how I could get them more equal. The newer one is just a little less powerful and breaks up way before the older one. I use the Plexi mod and the Tweed for clean sounds. Any suggestions or explanations??
