I hear ya. These cabs aren't for those in a hurry. And anyone in a hurry for something usually sets off some flags.
Not for nothing, but my Sadowsky took close to two years, I have a build queued at Tobias for over 12mos… and I know if they aren't answering emails promptly it's because they are making stuff. Roger, Mike, Alex…these folks care about quality.
Sheldon's gents can punch out a custom Dingwall in 6mo-8mos if you ask. That's "long" for many but very short for custom-ordered basses.
The folks familiar with the whole genre of custom builds (in which these are, every order is reviewed) know that 10-12 weeks is actually lightning speed for any builder (basses, cabs, etc.). Factor in his supplier chain, personnel, etc. 10-12 weeks is an incredibly short period.
I appreciate the time they take to make it right.
On the other hand, I'm guessing the folks who would complain about build times might not have ever ordered a custom bass in the past or realized this isn't a Fender assembly line. I would venture to say they would also find something else to complain about too.
I am sure the 'hate mail' folks will jump on me about this post. That's their 'tell' that my opinion hit home with them. I always consider the source. ✌
