err.....anyone know how to make Big Muffs able to work on a Marshall jcm900?

[Mecca-Random-PieMan!!!]

please help me friends

[Mecca-Random-PieMan!!!]

please help, its really important

[dadude]

You plug it in...

[tiges_ tendres]

do you have your in and out mixed up?  most muffs (I think) the in is on the left, not the right.

[Bernardduur]

Turn up the EQ a bit...... can help with an already overdriven channel

Also less sustain and more volume can do the trick

  Or a booster into the front end for more noise and more fun.

my main problem rite is the fact that my Big Muff sounds great when i have the gain on my clean setting low but then when i take the muff off all my other effects are dead quiet! i cant put my clean setting louder than my distortion setting because i just had my distortion setting finished, and it sounds crud with the volume low

Are you saying that the level goes down completely when you remove the big muff?  That sounds like a hot buffer in the big muff.  Is your big muff true bypass or not?

[Mecca-Random-PieMan!!!]

well the problem is that when the big muff is on its not even 'that' loud anyway

[petemoore]

  I think maybe the drift is...
  that problem with the BMP is that the bypass is much quieter than if the pedal is removed from the chain? IOW it's 'eating signal' in bypass mode...
  and output isn't 'hot'...it should be very high gain with lots of output.
  If this is the case it sounds like it's not working right, in which case you nead to provide the info needed in 'what to do when it doesn't work' thread, near top thread.

soo what do you suggest i should do???

This isn't that sort of Forum, please be polite and patient for people to answer your questions.

You mean that when you kick in the big muff, the overall level goes sky high? You know, that's what the volume knob on the Muff is supposed to do. You turn it down until the effected signal matches with the bypassed one.

Unless I get it wrong.

Listen. When i play on the clean channel on my JCM 900, the gain has to be quite high to get good volume out of it
When i put the BMP on, it sounds crud, and i hav 2 turn the gain down for it to sound decent again. When the gain IS down, the volume is low with the BMP on, and when it is off, the clean channel is quieter than the BMP!!!
     In short, Clean good with high gain, BMP good with low gain, but it is to quiet. BMP off means the clean channel is even quieter than BMP, and gain must be re-adjusted.   
WHAT DO I DO??

  Ok...I think I follow, this problem is a bit hard to define...
  The settings you like for clean can't be 'just switched' to 'optimal dirt tone'...without dialing knobs? [when using the BMP for Dirt].
  It sounds like you want to go from a 'lesser dirt' tone, obtained from the preamp [or amp], and that, for optimum usability requires knob twiddling...when
  You're switching off the BMP...which sounds good to you with it's knobs a certain way, and Also the amps knobs all different to the non BMP sound you like.'
  As you know..."and i hav 2 turn the gain down for it to sound decent again. When the gain IS down, the volume is low with the BMP on, and when it is off, the clean channel is quiet!!!"
  Welcome to the pit, finding your way out of it may be expensive or intrusive..and requires...
  Another amp setup and Pan or A/B type pedal would do it.
  A different preamp setup might be 'better.
  Adding a mod to your preamp that reduces the gain setting at the same time you engage the BMP...that's alot to do, is intrusive to the amp etc...
  Turning the gain down manually
  Or...
  Set the BMP and Amp settings for desired Dirt Tone [lower amp gain setting]
  Don't touch the amp settings, Remove the BMP, and insert a circuit which 'emulates' the clean or cleandirt tone you like [or can tweak to learn to like] to use with the BMP bypassed. This method is least intrusive, and has most advantages, fewest disadvantages IMO.

I've never used a JCM900 but some solid state amps' clean channels don't like overdrive. The JCM900 should be some kind of hybrid. Like the H&K I played recently, the clean channel can be too brittle and bright to be used with an overdrive stompbox decently. I got better results by using the second channel with the gain down enough to be clean. That channel's tone shaping was married to overdrive tones.

IMHO, I think that's what's wrong with the modern amps. They make the clean channel too goddamn perfectly clean and the second channel so damn high gain.

I think it's the best to use the amp's footswitch to change between the channels, and perhaps kick in the Muff if you can't get enough gain or sustain from the OD channel. If you just want to use the Muff to get solo tone, use the aforementioned second-channel-only trick.
