In several threads I've read many folks post about certain amps that really give their ears a workover. I've suffered with tinnitis for many years and for me, it seems a BF Fender is the one that bothers me the most. I love the tone of my old BFDR and Pro reverb, but playing them at volume really gets the ears begging for mercy after a short while. Makes no difference if I use a pedal or just open them up, they just wear on me really quick. OTOH, I can fire up my Germino LV55 and blast away and it seems almost soothing in comparison! What amps seem to do this to you?? Is there any way to EQ an amp differently to remedy this or is it just their inherent tonal qualities that aggravate one person's ears and not another's?
