Ceriatone / Overtone / Re: OTS Ford Model vs HRM BM clean channel
|

The HRM Bluesmaster and the serial #102 "Ojai" Robben Ford amp are 2 completely different sounding amps. Both sound great in there own right although.
The Ford amp has a Skyliner clean tonestack with NON-HRM OD it has more "chime'y" clean tones, and a much more focused OD w/ an almost horn like sound. This voicing has a Ratio control to balance the clean and Overdrive.It is also a very bright amp because of the large Master Volume Bright cap. The brightness is tamed with high pF (aka capacitance) RG-400 cables and a Dumbleator, also giving the amp an overall smoothing effect and increasing harmonic bloom and adding compression. A very "fast" response and a great sounding amp that all your tonal nuances will come out (good or bad LOL).
The Bluesmaster has a Bluesmaster (Marshall/tweed Fender) style clean tonestack with HRM "bluesmaster OD". The cleans are very girthy and has more Bass content that other voicing's. The Overdrive is also very fat sounding giving a broad range of Overdrive tones. The Bluesmaster also has a Bluesmaster Phase inverter (ala Marshall) and has less "clean headroom" then all the other voicing's. In addition it has separate Master volume controls for the clean and Overdrive. This amp also sounds better with a Dumbleator (but no need for high pF cables). I agree with this description as well. The Bluesmaster has that Tweed/Early Marshall quality to it, and a little bit of Blackface in to boot, and the clean channel can be driven nicely into overdrive and it is a beautiful thing. To me, the OD channel sounds better with the HRM tonestack disabled. It makes sound less like a hot rodded marshall and more like a cranked tweed/early marshall/blackface and to me has alot more touch sensitivity to it. Nik told me i prolly wouldn't like the HRM sound based on my amp preferences, and that it was easily disabled, and that i would prolly love LOVE the non HRM OD, and he was right on all counts. Mine also has a switchable PAB mod that allows me to switch the tonestack completely out, not just accentuate the mids, which i totally dig as well. As far as the RG-400 cables go, Greg and Erwin know way more than I do, but i can see where you would want to use some sort of high capacitance cable or a long cable run to take some of the higs out of the Ford Model, IF you don't want the highs there. I like alot of highs some of the time ala Freddie and Albert King and Albert Collins so i wouldn't go this route, but tone is a very subjective thing as we all know. Hope this helps! Gregg |

Cool, thanks! You know what they say about the simplest answer being the most correct  I'm anxious to see what effect if any bypassing the HRM tonestack has on the V2 plate voltage values. I know the tone changes dramatically and of course the volume level goes up due to the stack not being there, but I've always been curious at what else might be at play there. Of course now I'll have to wait since the remnants of the latest hurricane are makin it very thunderstormy here. Figures... |

Ceriatone / Overtone / Output Transformer Center Tap Voltage

I want to go through and check all the voltages inside my BM50, just for fun and to see the relation between different tubes, their voltages, and their effect on tone. The only voltage i am not sure how to check is the center tap on the Output Transformer. I don't want to do it wrong and fry it, so if someone could steer me in the right direction that would be great. thanks!

I just ordered two ANOS Telefunken ECC83s with ribbed plates from Mike at KCA, we'll see how they sound! If they sound good i may pick up a few more, if they are still available. I wish i had a bit more knowledge so i could change out the tone stack components to shape my tone, but i don't, so i am and always have been an old school tube swapper  i'll let ya'll know how it goes!

The HRM bypass isn't hard to do, you just put a toggle on the ground running from the trimmer board to the ground buss, but you may want to start with lowering the HRM bass trimmer though. This will prolly help alot. FWIW the factory setting for the bass trimmer on the BM is "barely on".

I'm in the US too (Florida) and aside from shipping, which is included in Nik's price all I paid was $26. I think brokerage fee and customs fee are one in the same, but I could be wrong. Mine came via ups as well. My c-lator shipped separately as I bought it later and I got no customs bill on it at all, I guess it comes down to declared value and contents as set by the exporter
