Hay Adam, I really like the various Lower Gain settings from the "Structure Switch" as much as the higher gain, depending on the song its nice to have that option. it was a pleasure to work with Dave as he went out of his way to offer me a number of options and also he did what he could do to meet my recording commitments (date & time). Once the modifications were completed, I got my amp back fast! in fact FedEx was scheduled for delivery on a Friday, and all of a sudden they changed it to Thursday! That one day early was awesome because the amp went right to rehearsal and I can hear the amp in a live band setting before recording sessions, that's a big deal for me and it spoke loudly of Dave's love of "His Amps" and his commitment to musicians.
Also the Clean Channel conversion from BE100 to SS100 was worth it for me, I'm more of a "Fender-Clean" fan than Vox, but the standard BE Clean is still wonderful! The SS Clean I feel is more versatile, wider and fuller with more depth, the "Three-way Bright Options L/C/R is very useful and in the studio, subtle changes can make big differences.
The BE100 is an amazing instrument.
