Re: I'm babysitting a Trademark 120 for a week!
I've got a TradeMark 10 and the settings are all over the place depending on what I want to hear. It would be great if you could save specific settings that work well for you.
I find that the Tweed setting gets pretty bass-heavy as you add gain. On the TM-10 at least, that setting is also significantly lower volume than the other two.
The California setting doesn't really have a clean setting - it just starts dirty and gets better as you add more gain. Personally, I tend to boost the mids with this one but that may be 'coz I'm trying to get Santana-like tone.
I use the British setting the least. You really need to boost the bass and I find a Tubescreamer/OD provides a better sounding crunch than the amp by itself.
Oh, and I have to keep reminding myself that the tone controls are active - a little tweak goes a pretty long way
BTW although it's a TM-10, I run it into a 1x12" Avatar cab with a Tech 21 speaker from a TM-60 in it. It's a damn good setup for practicing, and would be fine for recording if I could ever resolve my computer ground-loop problems.
