I know this has been discussed in previous threads but.... I do not have 100% clarity on the topic.
I am familiar with HBs #100-200 as well as the HB deluxe but have never tried any in the 1-99 range. Not sure about the accuracy but have read 1-5 were very dark, there was a lightening of the circuit from 6-to around 100, possibly another around 200 and up and definitely another at and beyond 400 which bearfoot adopted in the 3 knob hb. Anyway, I am interested in aural information regarding the 1-5 and 6-99 serial # range of the bjfe hb.
Thanks everyone.
