too much icepick in the eardrum mod suggested?
Posted: Thu Dec 26, 2013 4:02 am
proud owner off an dr-103 i've got one trouble although. 
mid and treble and presence when dimed , or even at noon makes the amp to sound very trebly.
sometime on certain notes (c and d on the b strings around 13th and 15th fret) are almost painfull for me.
it's like having an icepick drilling my eardrum.
my dr103 is a late 70's with 2input only and got the 47nFcapacitor at the cathode of V3A.
does the late 60's ( without the 47nF ) sound better,less trebly ?
it"s a pity because it's when the mids are up i catch a certain growl.
should i remove this capacitor ? does anyone have done this mod ?
is there any mods to tame this ice picking high mid/treble?
thanks for the answer
