I do not have the S&M model, mine is the OTS 100 watt, and I did my own mods following a combination of traditonal fender values and original dumble values. I originally had the J. Zucker mods and that sounded like cotton in my ears. Pure midrange. Now it sounds real cool. I would try, in lieu of tweeks to the tone stack or anything, turning the midboost off and the bright off. They seem to deffeat the purpose of tone knobs on my amp. I have no use for them. Also, this OTS tone stack has a lot of mids that funnel their way into the highs and lows so it really isn't "super" responsive. Try treb. bass. and mid. at 0. Then turn your mids up first. Then add treble and bass and listen for the changes. That will be the jist of the range you will be able to get and its a good way to prep your ear. I'm sure you will find what you are looking for, though.(quote)
REPLY: Respectfully, I am not a muppet nor am I deaf. I can also flip switches and turn knobs in combinations. Your time is appreciated but I am seeking "technical info" not pen pals. If you want to share your value changes, great. Much obliged.
