I also own the earlier and bigger version of this type of Behringer. To have a smaller sized one to fit into a pedalboard i ordered this pedal. So glad i did. After experimenting with this TM300 i decided to use it as an (almost) 'always on' device. With drive on max, high on nine 'o' clock, low at 10 'o' clock , level at eight 'o' clock, amp setting at tweed , mod at: clean and mic setting at classic,. It pushes the amp (Boss Katana) to a most pleasant level and sound. Creamy clear with just a tiny edge, as if playing a moderately pushed tweed amp indeed. With just that bit of compression that pushes the pick up's to a better working point making playing more easy. Of course it's always possible to adjust this pedal to all the other sounds, like high, hot, British, Californian and off-center speaker. For these i most probably buy an other TM300. This one i wil keep, like i said before, (almost) permanently in the channel chain.
