That is it, that is what I tried to achieve since years, I have invested an awful amount of time and money into this project but I am completely happy with the result...
Jacques, Hello and Happy New Year.
Now it is several years later and Lehle's RMI Basswitch models are discontinued. Since I did not buy any back when they were in production, I just bought an unsold RMI Basswitch Sonic Spark. My friend is a Lehle dealer here in the US, but he had none in stock; so I bought elsewhere.
May I ask why such a generally critically acclaimed product line was discontinued? I assume that it was the infeasibility of continuing to produce costly models that were not selling well enough. It just seems to me a shame that no more of these fine instruments will be made.
