What about the cleans?
Obviously a good OD tone is inmportant but so are the cleans. Does this setup work well with a C'lator?

Nik, The 68pF on the master is passing through lots of highs. That's making the amp very bright. If the master cap is omitted, the amp is less bright. Using a Clator rolls off the highs off the bright cap.
I have my amp with these specs for more than a year now and without a dumblelator/clator the od sound is unuseable

You're making me want to ask Erwin to mod my amps LOL

I dunno.

I'd like to get an amp with the OTS OD, but with less "in your face" cleans, without sacrifising brightness/sparkle (using a C'lator).
Not so much the direct cleans of a Twin (bit harsh), but a bit mellower/milder in the attack of the string. Hard to discribe; a bit of natural compression maybe?

The OTS is so direct is very unforgiving in a sense.

Would that be a Bluesmaster?

have you tried the Gil Ayan mod on the OD channel, which will filter out the lowest frequencies and make the OD cleaner.
Its simply a 4,7n-47n capacitor with a 10m resistor at the input of the OD.

No I have not tried this one yet... perhaps I should.
 

Did you tweak the trimmers ? IMO you can get a regular HRM to sound like a NON-HRM, easily

Steven, Reading your wishes, sounds like you want more compression and a brighter clean channel.
Maybe a resistor instead of a choke(more compression, I dislike it, but maybe you like it) will do the trick together with a EVM12L speaker.

Hi,

As for the FM50 brightness, it's more preamp zing than brightness I think.

I do have 68pf across the MV.

However, birds sang to me saying the bright cap on the vol pot should be higher, instead of 120pf.

If so, it'd make for brighter amp for sure, if the bright switch is used.

Maybe I should tweak to have both 120pf and 180pf bright caps (3 way switch) on the Vol pot.

On the matter of #183, I do like it a lot, actually. You might want to try different settings on the OD controls, instead of the soft V positions like usual.  Turn in up a bit more.

It's quite smooth, with a lot of body.

As for tweaks, I guess it's not a matter of just changing tubes. You need to also tweak other places.

Of importance, I have found lately, is the wall supply.

If you ever thought that the amp sounds so different day to day, check your wall.

These days, with more and more ppl in my area, at times my V1 plates drop to abt 180V, and that does spoil things.

I have ordered a regulator from my tranny winder. It allows for adjustments to the wall voltage into the amp so that I can set correct voltage, each time.


Thanks!

Nik
