I was wondering what people thought on a 19mm sixer. I have played TRB's before even the TRB-JP. Are the TRB's 18mm or 19mm? I remember the JP was HUGE (maybe 20mm?). Also I played an Roscoe SKB3006 and I liked it quite a bit, but I noticed it was tighter than the yamaha. I've also played the Cirrus 6 but found it was too tight for me. Also if anyone know what the width is at the nut on a TRB6? (I'm looking for all these specs for my custom sixer) Thanks!
