Hi Erwin,

As I stated in my message:  do you do the mods yourself? Now you do the mods yourself I am very interested. I live in Amsterdam,  I can bring the OTS 50 and pick it up again. When would you have time? How much would it cost me? Thanks! Lovis

Hi Steven,

I have this same problem and I have been fiddling with the Amp (OTS50) for one and a half year, and it still has this strong attack and all the other symptoms you mentioned. I would love to have a way to change the tone to a fluid and bell-like caracter. Is it Erwin who is sending the schematics or does he do the mods himself maybe? Thanks in advance, Lovis  email: lovis.fofrofo@gmail.com
