Yesterday I had the opportunity to compare my OTS BM with a T-R CRS V2 (Same Cabinet).
OK, the T-R has won the match:-(
One of the most serious differences for me:
The T-R has compared to my BM simple a thicker tone (and more harmonically rich)...

Has the normal OTS (not BM or HRM) in the clean channel also so a thick tone as a T-R?
Is maybe the result with Mercury Transformers better?

I've always wanted to see/ hear a TR vs. Ceriatone bout!

I see, though of course in such a short time, maybe with a little tweaking you can cover the thicker tone of TR perhaps?

Is that much of a difference or just barely noticable?

How would you descrive "thickness" cause I think ceriatones are thick with the proper settings.

Thats interesting. I've always wanted to compare these.

Not that much difference if you rely on pedals.
I have a Bluesmater HRM 100 (with Mercury OT, PT and Choke)
An FM 100 OTS Modern Eagle
A Fuchs ODS 100
and a Two Rock Studio Pro 100


They are all really good but the TR gets a great clean sound for sure...you have to work to dial the Mayer out of it.
(or pull the mid boost)

My BM has very thick clean and OD tones. I think speaker and tube choices can have alot to do with it, though.

Are you referring to a Two Rock Custom Reverb Signature V2? If so, well of course it's going to sound different - it's a whole different animal than the bluesmaster. I don't know which dumble style circuit is in it, if any, but unless it's a bluesmaster variant, it's going to sound quite different. And you're going to pay a whole lot more for one of these, if you can even find one.

It all depends how you modify your amp !!!
No two rock sounds better than well tweaked OTS with the Mercury transformers and chock, especially drive channel.
You can tweak OTS clean channel to match TR clean which is great.
I’ve spend months to make my amps sound better than my TRs: TR Jat, TR reverb Sig 50, Sig 100 and Kimock and when I did, I’ve sold TRs and bought more OTS and couple of custom build guitars. Wink

Don’t be shay to experiment with the components: slope resistor, coupling caps on both channel, drive inlet capacitor and following resistor, V2 snabers end so on.

Hahah thats good to know Pickmasta.

I remember you have a layout somewhere in this forum for an OTS modded for a Joh Mayer TR. Is that your latest? I am interested to mod my OTS 50 to JM specs in the future. I hope you can help me out sir.

 Cool

I definitely will my friend. I’m on little tour right now (writing from my mobile). In couple of days I’ll post simple but useful tweaks which you all enjoy I hope .

Sounds great sir! have fun on the tour.

I think I might go with your mods instead of converting to BM like I first planned. I figured it involves a lot of components and might aswell build a new chassis than kill an ots circuit.

Hi There,
Once again, here is a layout of the OTS FM mod.eagle. easiest platform for really great tone.
With offered mods (in green) you‘ll get clean as good as TR or Bluesmaster with 100-120pf High cap on volume push pull, fat but sparkly same time.

Important tip! When you use single coil pickups, you can switch OFF V1’s  0.05uF NLF cap for fatter, more compressed tone , but for the humbuckers  better switch it ON otherwise you will have to much sug and early brake up.

Drive channel (ratio X – line mod) will give you fatter and more open drive tone which you can smooth with higher value snubbers and if you use 120pf cap on volume’s bright switch, accordingly you have to increase V2,2 snaber’s capacitance with 3 way switch with 470pf or 680pf caps (you can experiment and chose cap’s value according to your taste).

On the mid-boost switch increase cap to 470pf for slightly more high mids and remove 0.001uF cap on bass pot for slightly more lows and low mids (or better introduce a mini switch).

Finally change presence pot to 1K linear for better early and smoother action.

I hope this mods are easy to perform and you will have better sounding amp instantly.

Best wishes and good luck.

Hi Pickmaster, I'm interested to know if these mods were performed before or after your YouTube clips?

So in all, you have the mods listed in the schematics with also MM tranny and choke?

Hello mate,

All recordings are after mods,  with MM transformers and choke.
Iron makes noticeable difference when play loud and I’m sure Nik’s modern, home transformers do the great job as well but I’ve asked him to supply MMs.

O --- M --- G !!!

I should've done this earlier!

I removed the LNF and the bass cap

Cured all my ills. The stiff attack I was rambling about was gone

Thanks a lot! Pickmaster. When I heard "more compression" on the LFB from your post I immediately removed my chassis and did it.

Now my sound has the BOUNCE man that bounce. And my overdrive is now set lower and I can turn up the ratio.

Thanks Pick Smiley

I've been considering a second ceriatone after my BM and I was leaning toward the FM or HRM with different voicing on the clean to try retain the same cleans as the BM or towards two rock territory. Got me thinking perhaps I should go the FM route with your mods for the cleans...
