Fx session high frequencies filtered out

[jvfire]

In a great disappointment I realized that my MX effects section responds weakly to frequencies higher than 2khz while over 3khz doesn't respond at all. The tone button seems to be reversed (?), at left side I get the higher pass but still under 3khz... Please help

The forum for this site made me realize a lot of things.

Since it's an analogue BBD delay, it is a little dark in character, and the bandwidth varies with the time setting. With shorter times and the tone button to the left (yes it's reversed) you should get more than 3kHz through; around 10kHz with some roll off (the Reverb setting is darker). With the longest times you get a roll off at 2-3 kHz and even lower if the tone control is to the left.
