AmpCapasitors.

I am looking for caps that will make the amp to clean up from 5 and down on my guitar volume knob for my single coils in the middle and neck and for my bucker in the bridge I want the amp to just melt into the wall of gain of doom from 5 to 10. I am using SD's invader which is pretty hot and Spina's TS9 so the signal that arrives is pretty pushed but I still want maximum gain possible out of my pre-amp considering the earlier requirement for a guitar volume knob clean up for single coils. Mine is a six knober 50MV AOR Pro-Tube Lead.
 
Re: AmpCapasitors.

You expect way too much from a cap.

Well ....... :15: can they sort of, kinda' of get me closer to that .... for example, I bring my volume to about five, switch to Tex Mex single coil in my neck and turn off the TS9 or(for the crunch) bring the volume to say 9, turn on the TS9 and switch to duncan's Invader in the bridge???
 
Re: AmpCapasitors.

Caps in general only have control of frequencies. You can re-voice your amp by changing the tone stack,But that's not gonna help what your trying to accomplish.
 
Re: AmpCapasitors.

Ques que se tone stack?

At the tone...Press 1 for English. Press 2 for Hang up and go learn English. :laugh2:

E tone Estacko is De parto of ju amp wish mako it Esound Soooooo good. Que pasa? Nada!

In short, A tone stack is normally a group of Capacitors & resistors of a pre determined value in the 1 st stage of the pre-amp which is responsible for the general voicing of your amp.

OUU monfestique ziz fohum ruliz mach bettyor zen dimarziO fohum ....
Anyways so its just settings of caps and resistors or is it different manufacturers that you go for, or actuall mods?
 
Re: AmpCapasitors.

I think you gotta run the master open and the pre gain lower as well as mix in a one or maybe two 12At7 tubes in there. That would make a big difference, also lower output pickups, if you have hot winds it won't clean up.

While the caps won't nec make the amp cleaner when swapping the same values, changing the value of a specific cap or resistor will add or reduce gain, treble, bass, everything..... That amp is extremely similiar to a JCM 800, which means much of the same stuff will benefit that amp. I had great success tweaking my AOR 50 to a much more dynamic, open space. I big part of that can be done off of the input jack resistor and volume cap values. Search google for the JCM 800 'warming mod', very simple for a tech to do and will really be a great start in the right direction, if not everything you want. Stock those amps are a bit too gainy, bright and stiff. There is a lot that can be done.
 
Re: AmpCapasitors.

the "cleaning up as you roll off guitar volume" only works properly in cases where gain is 'not-too-brutal'. If you're employing tons of gain in the pedals, and then some more in the amp, then sorry...it's not going to clean up nicely. Also, an Invader, c'mon! Just turn down the gain, and open the volume a bit. Amazingly, even ACDC is cleanish, just very loud, giving the impression of the wall-of-doom...but not. I guess if it's loud loud, it comes across big.

I think you should have a mess about with the gear you have before moddding anything. I use a Marshall with a very similar circuit as that AOR, and an SD-1 instead of the tubescreamer, and with the preamp on about 7, with the SD-1 off, and the guitar rolled off to about 6, its pretty clean. Not pristine, but you'll have trouble getting these kinda amps pristine at the best of times. Try turning the preamp down, and get the master really cooking. Thats by far the best way to run these sort of amps IMO.
 
Re: AmpCapasitors.

kmcguitarsm,
Is there a common name for this mod that you mentioned?
Kevlar,
Thanks as usual dude, did you do this particular mod for yours? Also how is it different from kmc's option? I am gettin a MASS attenuator so I guess I could push and crank the MV and still able to experiment at bedroom levels?
 
Re: AmpCapasitors.

I recently got a MASS and i HATE it! :) it totally sucks the mojo right out of your tone. Both my 1981 jcm 800 and my '97 mesa trem-o-verb sounded like total butt with the MASS. I'd rather play with the dynamics intact at a lower than "ideal" (cranked) volume than suffer the indignity of flat gross sounds at "reasonable" volume with my dimed amp wheezing through a straw.
 
Re: AmpCapasitors.

Hmm ... a lot of people praised it here, and its the only one I can afford, but you are stressing me out .... Kevlar, KMC where art thou?

Forgive me, Grasshopper.What EXACTLY is this knowledge thou seeks?
 
Re: AmpCapasitors.

The warm mod(look above) recomended by Kevlar how would it differ fuctionally speaking from you tone stack mode???(spoken with paranoid, heavy, russian accent while pinching the edges of fingernails with other hand's fingernails)

If you feel your amps is a tad bright? The warm mod is the way to go. I wouldn't mess with the tone stack IMO. The Pro Tube is voiced similar to a JCM 800. Any tone stack mod will mess with your tone control functionally.
