I agree, I run mine with a Tube Works Blue Tube.

Ooh-I used to have one of those. Definitely warmed up the tone! I sold it back when for a bass driver...which I sold for...yadda yadda yaddaI agree, I run mine with a Tube Works Blue Tube.
Jaycephas, you've got exactly the same rig that I have! A B-100R, and a PF800. Except I only have one cab, the Ampeg PF-115HE. Like you, I'm just in awe of the awesomeness of the tone, but also of the similarity of tone between the two amps. The only thing I plan to add is a PF-115LF, in the bottom position.So a b100r came up on Craigslist - original owner, great overall condition, priced right. I read all the TB comments on this amp and it's mine now!
Took it home and played all my basses through it - what an amazing-sounding combo amp! Really has a punchy, vintage vibe. I also happen to have a PF800 and two PF115he that I gig with regularly. I A/B'd them and can get a similar sound, which is great for me. I can use the b100r at smaller gigs and practice. I have some time this weekend and think I will run the line out of either the PF800 or the b100r and see how massive a 'wall of Ampeg tone' I can get!

By the way, So far I really like the onboard compressor on the PF800.
Another 115HE? I hadn't considered that possibility. I have to admit it makes sense. I was thinking a ported and a sealed ran together would be "ultimate". But maybe two of the same exact cab would pull the maximum from my PF800.I agree that the onboard compressor does a good job. However, I have a Diamond BCP-1 and an Aguilar TLC that are my 'go to' compressors and work with my respective basses. As far as the cabs, I might suggest that you get another 115HE - the sealed cabs work well together, and I get plenty of bottom end when playing my 5-string basses.

Just wondering, how would you describe the tonal difference? I wonder what the difference could be attributed to...Here again...
I have been testing this and that lately and always come back to the B-100R. Peggy (AM has dropped of the logo ;-) ) is my third B-100R and I have a feieling it's here to stay. The others were good also but no match to this one. Don't know why it sounds a tad better than the others I' tried but it does![]()

Hi guys, i'm about to buy myself a used B200R that i found at a local dealer, but at the same time a B100R Full made in USA just poped up on CS near where i live. So for all those who own both, what do you guys think ? B200R made in china vs B100R made in USA ? is the pre amp tube on the 200 a thing ? knowing that I'll use it for rehearsal and smal to medium gigs !
