The 100B and early 101B are VERY close in design and tone. The difference between the two is a matter of a few parts and a minor variance in filtering. By your screen name; “Bogner100B” I can tell you aren’t biased. Not at all! ;)

Let’s go beyond the Ecstasy 100B hype:

I owned a 100B model for over a year, and sold it in favor of a 96 Soldano SLO100 which I still own to this day. The 100B “hype” is nothing more than that – hype! You want to believe that you have “the best sounding Bogner ever made” – but the truth is you don’t. If you personally prefer your 100B – than that’s cool. But please stop with all the BS!

From Bogner;
“Comparing a cab switcher XTC to a no cab switcher XTC is splitting hairs. Some may prefer the cab switcher model – some may not…”.

When I purchased a 2007 XTC, the same seller also had a 100B, 101A, 101B (white chassis) XTC with cabinet switching. I played all the amps in his studio (including the 100B), and begged him to sell me the 101B cab switcher model! Which he of course refused. :( I took the 2007 XTC home only to sell it 3 weeks later. I have yet to play a “Classic”, but I hear they are a very nice amp also.

The 100B is sweet, but they’re a bit loose and squishy sounding to me. Doesn’t really matter what amp JB plays – they’re all going to sound great! LOL

I didn’t care for the 2007 XTC 101B I had… I now have a 1994 white chassis with cabinet select that absolutely slays! Best Bogner amp I’ve ever played – and I’ve played many. The Mercury Magnetics transformers Bogner used in the early 90′s really make a huge difference IMO. I spoke to Charlie at Bogner recently, and he told me to “hold on to that amp!” The build quality alone is something you just don’t see very often. It’s SO transparent – yet SO smooth with the just the flip of the excursion switch! The cabinet switching is as cool as it gets. I have a 2×12 Cornford cab w/Alnico Gold’s output #1, and a 4×12 w/V30′s on output #2.

Someone who goes by the name of “Squarehead” on HC was bad-mouthing the white chassis models? Maybe he’s pissed because he played one – only to find-out that it sounded better than his 100B? LOL! I owned a 100B back in 2000, and while it sounded great, I prefer the white chassis 101B hands-down! The 20th Shiva a sweet amp too.
