did, t had the time before now to dig in the amp but tried some things.
firste i found out that i did 't use the tasker cable, so i tried to find it somewhere and i did.
id says on the cable:c114,  2 x 0.25 - 23 AWG O.F.C noiseless microphone cable low capacity
specs are in this file: tasker c114

then i played for a while toggled with the tone controls and really got frustrated.
where you, with a normal amp, turn high down get a specific results in that region, in this case it did not.
so i tried really weird stuff, turned the pots completely down or up to see what result it would give.
it does not react like a normal amp
the noise gate is a problem of some things on this amp.
if you have a little edge on a clean sound and you sweet pick a string, the sound comes in like using a swell pedal.
soft notes disappear suddenly while you see and feel the string still moving.
using the tubescreamer effect makes this worse

because i have been operated on varicose veins in my leg today i cannot tweak with the amp and guitar like i would want.
but as soon if i have more results, ore find a solution i will post it.

things that i can try is tweak pickup hight, see if this helps
