Holy Jeebus!!

Very nice!!

So i'm thinking of tryin this with the BM think it'll work? 

I kinda wanted to start a thread for the Bluesmaster, to get an idea of how many of us, at least on this forum have Bluesmasters. I don't think that there as many of us out there as the other Models, and there seems to be not so good a consensus on whether owners love em or hate em for one reason or another or differ on how they think they should sound, so how bout you amp's specs and your opinions. i'll start...

50W HRM Bluesmaster.

Built by Ceriatone

Mods: Switchable Sag Resistor, Switchable PAB Resistor 68k/22M, Half Power Pentode/Triode, 3 way switch for HRM: On with 33k resistor, Off, On with 100r resistor (stock setting).

2x12 Combo Cab built by GabKits with 2 Weber 1265 Alnico Drivers.

Ceriatone C-Lator


To me, the amp sounds just as it should. Amazing cleans reminiscent of a BF Fender, or with the right settings early Tweed Bassman. It is more scooped than the rest of the OTS series, and that can throw some people off. The clean channel sings and sustains, and when pushed either by PAB or an external boost pedal it can straight up rock! It is very punchy and dynamic and just very big in every way. As far as the OD goes,  I think that alot of confusion comes from the fact that being a D-Style amp, people expect a ceratin overdrive sound out of the amp, but the Bluesmaster sounds nothing like any of the others. The OD is gritty, nasty, raw thick and not overly compressed. I'll be honest, the OD sound best to me with the 22M PAB resistor engaged. (the PAB should always be engaged when the OD channel, bypassing the clean tonestack and allowing the HRM stack to control things for best results on HRM amps). The 22M resistor was supposedly the original design, and the 68k was fitted so that there is less of a volume jump when the PAB is engaged. if you don't wanna mod your amp, you can get the same effect with a hot clean boost pedal.Once you get a good hot signal going to the OD side and the PI power section, it is a different animal. Still, raw, still edgey, thick, not overly compressed, but it will sing and sustain forever. i run mine this way and i keep the OD trim at about 11 o'clock and the Drive at about 11 o'clock (3) and the level at about noon (5) and have no issues with fizziness or weak sounding OD at all. That's my opinion....

Very cool!!! glad you got 'er goin!!!

Gregg

i would email nik.

gregg

have you checked the wiring on the override switches on the back of the amp? they could be inadvertently wired incorrectly or shorted. also are both switches in the right position?


Gregg

go with your gut. that's always the best thing. also, if you are really unsure, email nik, tell him what kinda sound you are looking for, and he can steer you in the right direction.

Woohoo! glad you found your sound. it's a great feeling. 

Good to hear from you too, man!

Yeah, I love em! I actually got another set from tc tubes that are matched a lil better and he burns them in at the plate and screen voltage you specify. That set sounds even better! Very nice and very tight bass, which is always good with the Bluesmaster. So far the Tung sols and the TAD's are my fave new production tubes. I really wanna try the winged c's next, since I have read so many mixed reviews, I kinda wanna try em for myself.

Gregg

Chris, did you ever try the Tung-Sols?

Gregg

Did someone say my name again?  .

As far as the cleans go, the Bluesmaster has more of a BF/Tweed Fender Bassman/Marshall JTM 45 thing going, especially if you use older GE preamp tubes. The cleans can go from BF Fender to Tweed Bassman depending on how you set the tone controls. The mids are more scooped than the rest of the OTS series, which gives it the BF vibe, but it also has a huge bass response, which can push it into Bassman territory, especially when you push the clean channel hard either with a nice boost pedal, or with the internal PAB and cranking the preamp and master. big, bold, with awesome overdrive!

The OD side is more marshally, and can go from JTM45 to early plexi depending on how you push the drive, OD Trim, or if you have the PAB set up like the original Bluesmaster amp with a 22M resistor vs 68k resistor. The 22M resistor provides even more of a boost to the HRM tonestack. ideally the PAB should be engaged when using the drive channel, otherwise you are going through two tonestacks and things can get muddy.


here's some thoughts on ther Bluesmaster from TGP posted by user erwin_ve

Blues Master. Think raw early Fender/Marshall
tone on steroids. The tone stack is decidedly bassman territory,
however because of Dumbles many other difference it is far better IMO.
The cleans here are the best cleans I think I have ever heard, dumble
or otherwise. The cleans will sing and sustain!!! The OD is much less smooth and much less compressed than the above amps. It has some early Marshall vibe to it. Boosted cleans with this amp are to die for. The OD is a bit more raw and edgy then some of the other offerings but with boosted cleans you get the smooth side of things and with the OD you have a less polite and refined tone.
Somewhat like the first Dumbles, though different. Lots of punch, sustain and singing but not as smooth as some of the other offerings. This one can be thick and dense too. Not dark and crappy, just "meaty"...
Open clean cleans to mean and a little rude.
Big fat sick blues machine. Lots of character or soul. This amp will try and steal you girl.Like a tuxedo on a cowboy?.... It can play nice but it can still stomp in the dirt.


Overtone HRM Bluesmaster
Overtone HRM Bluesmaster 100
This amp is completely different. It has different cleans compared to amps above... cleans are more mid scooped, more fendery if you wish but with a lot of low end. This amp possesses a punch like no other amp. Again not as much OD as nonHRM, this amp makes you work for the tone too (very dynamic).


Hope this helps!

Gregg

Thanks, Wyatt! Been talking with Nik about building a 5F6-A with some mods per your suggestions!

Gregg

Forgot all about this. Here is a lil layout out i made showing the mods, for informational purposes
