In dit draadje werd al eerder gesproken op de invloed van de Schilke modellen op de wat oudere Yammies. Stuitte bij toeval op een oude post:

Hieronder de betreffende
suggesties:
buying a used Yamaha 636 a couple of years ago, I tried to make my own comparison chart for the old, 3-digit models. Here it is - these are my guesses, using the info from Yamaha's web site on their older models and the Schilke Loyalist's site on Schilke models. This comparison is based on bore and bell size; Yamaha uses different materials and finishes than Schilke.
I'm sure everyone will fix anything I have wrong. -- Joe
Additional note on reading the below list: I consider the 632 & 636 to be B6 clones, the 634 & 637 to be B5 clones, etc.
