Hi Thilo,

Treble bleed (usually 0.04uF cap and pot) unfortunately cuts not only high frequencies but also high mids as well.  12 way rotary with 100pf, 200pf,…..1200pf range SELECTS and cuts only highs and very little high mids on higher capacitance so your tone stays richer.

And Yes, stick with the changes here, just introduce 1K linear pot on the presence and if you gona use 12 way rotary, than V2 snubers must be both 330pf  than you will have wide range OD tone.
Be cool.

Sorry to revive that old thread. I'm still considering to let my OTS 50 getting modded.
It was built in march 2008, so should be like a S&M.
I really like that clean John Mayer/SRV sound, so I'm considering the mods posted in this thread. But since I don't have a recent OTS 50/100 but an early OTS without any mods I'm not sure whether I can use them or better stick with the mods posted by Pickmaster in the thread http://ceriatoneforum.com/index.php?topic=740.0 which were done with an early OTS 50, too.

Maybe someone (best would be Ika himself I guess Smiley ) can chime in here?

Thanks!



No, you don’t need the complicated mods in my old thread you’ve just mentioned.
Better to perform mods mentioned in this thread or one I’ve published couple days ago here  http://ceriatoneforum.com/index.php?topic=4753.msg22766#msg22766

They are almost similar mods and work great for all OTS non HRM amps.
My first amp was S&M 50 and it sounds nice after this mods.
Cheers

Yes that was a pretty quick mod which gave me what I was yearning for in this amp. I just removed the LNFB cap and left the 22M resistors. Is it okay to leave them there? I figured I'd have to heat and mess with the sockets to remove the 22m resistors so i guess its ok to leave them there with no cap instead?

I am looking forward to that "Well Tweaked" OTS that could blow away or hang with Two Rocks as you said but am also intrested in your JM mods for OTS. What do you suggest I do? Follow your old JM mod layout along with these new mods you posted here of the FM mod eagle?

Thanks again! Love the new more musical girth of my tone so far.

Live the resistors there, no problem at all.
My first amp was S&M 50 and second was OTS100 so I needed to do much more tweaks than new OTS FM modern eagle which already has necessary mods.

You know, JM’s amp is big, clean one channel TR similar tu Dumble SSS which is great platform for clean tone and pedals in front of the amp.
But with offered mots on OTS you will get close fo sure and you don’t need other tweaking. Probably you can try different capacitor values on the master pot: 33pf, 47pf, 68pf and so one.

Cheers

Cheers guys! I’m glad you’ve liked the results.
By The Way ! the mods would apply to all OTS amps except Bluesmaster and other HRMs which already have NLF cap removed and lower slope resistor.

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. 

Cheers

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.

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 .
Cheers

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.

Remember, if you are a Jedai you have to build your own lightsaber!
Let the force be with you !!! Grin Grin Grin

Thanks Greg, Smiley
Good tone always inspires us to play well.
Cheers mate.

Hi Thilo,

Not much really, you need micro switch to switch on and off  V1s 0,05mf negative feedback  capacitor, 0,01mf cap instead of 0,005 between two resistors before the X –terminal, and try different snabbers on the V2 for better drive tone.
Be cool, cheers.
42  Ceriatone / Overtone / Re: OTS Dr. Irka mod on: September 30, 2012, 04:15:59 PM
Hi Tony,
Yes, It was an early S&M. Now Nik does great job on modern OTSs and you don’t need many mods.
Be cool.
Cheers

Mini hambuckers? sounds big and sweet, nice reverb too, what is it?
44  Ceriatone / Overtone / Re: HRM Bluesmaster setup advice on: August 30, 2012, 05:11:40 PM
Gentleman, it’s great to see that you are all enjoy tweaking and experimenting with your amps. I’m sure it is great fun, but on the end of the day we all need great amps to make music which is most important.
Any chance to hear your sound clips, your playing? Especially before and after tweaking.
Perfectionism is great but some times tweaking becomes an addiction and playing, practicing suffers badly.

Hi,
I’m sure you like  the EV but you can consider FDM speakers with built in 9db attenuator.
