This make me think. How does John Mayer make his sound thick but doesn't clash with the bassist. THough sometimes his live sound is a bit muddy I admit.

Thanks I think I will indeed go with the 68k and I will try to do a before and after sound demo.

Thanks for elaborating.

Looks like lowering the slope resistor is my cup of tea. I have one concern though. If the sound "blooms" with more signal hitting the OD stage does it stand to reason that there will be more flub to the bass particularly when you leave your clean EQ settings ( I usually put treb and bass on 7 with mids on 3 ) and use the drive?

I don't believe so though cause I thought the lifted LNFB and bass cap mod will introduce more signal to the rest of the amp and cause bass distortion/flub but nooo, my OD became thicker but more defined with much less flub.

Oh yea? Thats cool I also guessed we play the same style

Was your Jazz setting like mine? It only gets enough bass when you crank the bass knob?

I have used my amp in a rehearsal without the LNFB and the bass cap. In a place where volume is very restricted I might add. And I can tell my bass player likes my tone but he doesn't say it. I guess I know why... lol.

Anyway most of the bass and girth gets LOST with my loud drummer. So maybe there's not to much afterall. But then again, the drummer is oblivious of any volume restriction.

THats very interesting on the alligator clips. Could I just clip it on and off while amp is operating ? Better to turn off?

I should re phrase my post. I read back the thread and I think I get it better how the 180k slope resistor concept could work well. Perhaps I'm just a bit baffled cause I am about to do the new Dr. Ika (Pickmaster) FM ME / OTS "TR" mod with the suggested 68k slope.

I just hope bluesking could read this and shed some light into other aspects of the mod like is it more punchy or what other than being more scooped. And also I hope Pickmaster could chime in too so he could share his ideas on this.

Yes his cabs are a top secret ingredient for a killer amp.

Which one of your settings / mod / stock config gave the most touch response? Or compression?

Thats interesing on the 470pf. What style do you predominantly play bro?

Thilo didn't you make a switch for LNFB? Why not switch it on and see what the 68k slope did?

This is great overall but I'm now more confused

Pickmaster indeed said that lowering the slope resistor to 68k does wonders in "bloom" and "touch responsiveness"

Now just what exactly does modding the other way (increasing slope resistor) do to the sound? Please elaborate to me kindly and thanks a lot.

And about the "high plate" and "low plate" thing. COuld you guys explain that concept and what made the difference between the two and how they impact the response given the slope resistor values. ..I've read that "high plate" versions yield a stiffer feel. Now those who know me know that I am rather allergic of anything stiff. What can I do for more responsive compression then? You know, so I can strum colorful chords and yield a glassy pleasing chirpy sound as opposed to ear fatigue inducing stiffness.

Kinda like John's tone here (he is indeed using one of his early Dumbles here through a Fender 2x15 most probably)

I'm sorry fo r asking these I have a rather lower average knowledge in amps.

THanks for all the well meaning modders and tweakerses you guys.

I first removed the negative feedback then tested my chassis so I know what it does. I then removed the bass cap and tested the chassis again. The change was very subtle. Maybe If I've done it before the LNFB then I must've noticed more increase in bass. But with what I did, there was just a slight increase in bass. I think you dont need to remove yours. But me, I liked both mods.

hahah yeah only the bestest for v1.

What is the effect when you swap the jan phillips and the rca in v1 and v2? Most ppl I kno with an RCA almost always put it in v1.

Yes I get the same effect when I put my GE AT7 there but the effect is more sort of prononced when I use it on v1 it seems.

What was your AT7?

You can build anything to to do anything after you make a flying machine Kudos sir.
