BBDs operate as an analogue sampling system, so the audio bandwidth is directly related to the sampling frequency, while the delay time is related to the number of stages in the BBD chain. So if you want a long delay with a wide bandwidth you need a lot of BBD chips running very fast... and that means a high cost which isn't likely to make it an attract purchase.
The advent of real digital delays overcame that cost/bandwidth/delay time conundrum and virtually killed off the BBD solution overnight.
Today, the 'dull' BBDs are often sought after specifically for their own low-fi sound...
Yeah, I have a TC Flashback which has various models including old school delays and tape echo. I tend to use a clean digital delay model myself but I get using some BBD models for authenticity.
