Sorry for the english post but i need help with the tt-loop LND 150 and a lot of
TT user can help me .

I installed the LND 150 loop in 3 amp that i have built and and i have problem...
when the loop is on the amp sound very trebly when the amp volume is turned down especially with
overdrive channel .... when i rise the volume the sound is less trebly but i have to turn at reherse volume which is
a little high for home ...i have tried with A & B loop input ..i tried to remove the C4 from the loop ..i tried all send and return levels
from the loop and finally i used pedal and rack FX but the sound is always trebly al low volume ...
the loop is in series configuration and i connected the output of the loop to the PI input capacitor ...   
           
Thank in advance for your help  :guitar:
