If I could drop £5K on new ears to get rid of my tinnitus which is beginning to make it tricky to actually play then I would be flogging vintage kit right left and center. I am not joking. £140 for being able to play for the rest of your life is absolutely nothing. Just peanuts. And if you do not like the isolation but play with a drummer or guitarist who has no restraint, and we all do, then get over it and look after yourself. Until you have tinnitus then it is just something which happens to idiots. When get that 'oh :(' moment it is just too late. It is not if but when it will happen. No, really.
