in red channel, the "blanket" i think it is necesary, because eq section is tuned way to bright, and the feedback loop is off (feedback loop make the power section more warm and clean). wehn I took the 22k resistance away in the orange channel, also I changed the 500pf to 250p cap in the eq (now...

I think tremoverb was the intent to make a more versatile Dual Rectifier, and it has a very big diference in the voicing, besides of the efect of reverb and tremolo even if they are bypassed, tremoverb has one more stage after eq-master and reverb, just before efects loop (V5b). just now seeing...

so, finally i have conclutions that satisfy me thoughs. first, i could not do clips to show waht I did experiment, because it 1M to 250K change in a way that you can barely record with my cheap preamp, but sure you can feel. but i have a better theory background to explain you waht happend. I...

ok, i think that I Fail! :cry: I put a switch and a 330k resistence across the 1M pot, and I did record, but, almost was not any diference, the only diference was that wehn the pot was "virtually" 250K the sound was little more tight in a low mid range, barely i did hear when i was palm muting...

yes, change caps on plate resistor its another good way to take hi end without put a blanket on it.

I would love to do that, but I`m in Chile, south america. I never said that are just the pots.

So, I open my tremoverb to change the pot value and finaly do a comparision and clips, but ironicaly, my 2 channel dual rectifier tremoverb has 250K pots!!!! Uploaded with ImageShack.us waht this mean??? every recto has 250k??? or just the new ones??? do the 2channel rectos pre 500 has 1M...

Not to convince you, for the people that are reading this post and deserve good quality information, yes the LDR`s bleed trough in some special or extreme conditions, but in the 2 channel arquitecture there is no one that will bleed, or work not so acurate then a relay because no one are in a...

that it not all right, for example if you have an LDR that has 100ohm of resistence wehn it is on, next in series to a 470k resistence (like just after the gain pot in a 2channel recto) you have a 470,1k ohm in total, and every resistance have a 1% of variation at least, so, in that case it...

100ohms resistor in the catode between 1uf and ground maybe are there emulating the resistance of the LDR that in the 2 channels are. Regards.

It is very interesting in the history of mankind there are many examples like this. paradigms are so strong in the minds of people. in fact not surprise me if someone did the mod, and found no further improvement because the mod is "way too easy" for his mind. think objectively sometimes is very...

Yes, the tremolo sucks, the switches can be usefull, but the 2 knobs its hard to use to, because are so far away from everything and so close to the power suply that meaby degrade the sound a lot if you pass the signal thru them. I just have a great idea!!! the knobs can be use to control the...

I was looking the 3 channel rectifier schematics, and I realized why theoretically it sound diferent than a 2 channel rectifier. the gain pot of channel 2 and 3 it is 250k that should be sound a lot more scoop then 1M pot, I did try this in others amps and it is a very big diference wehn you...

Yes thats why I just pull of the resistance, I wan to deal with the opto later. meaby with a 3 position switch instead of the clean/vintage hi gain 2 position switch.

by the way, this mod can be aply to every recto Orange channel, I dont have another recto to try.

for me Orange channel was dark, not fat, now I feel it very fat with precense. I dont change the way of saturation or armonics texture, I change the eq curve, so its the same feel, more fat and with more natural presence. to make a grafic reference idea...

HI! I m new, and I don´t speak english very well, but i wan to share this to you. I made a mod to my tremoverb, and the name is F.C.T.Mod ("full chupalo turbo mod") I have some years of building amplifiers for pleasure, and two years ago I bought a tremoverb head because when I first heard it...
