Some amps have so much headroom that all a pedal does is sit on top of the sound - it never blends in with it. Nobody likes the sound of an amplified pedal.

Not exactly true, what about those Groove Tubes amps that had a ton of headroom that were designed to work with O/D pedals?
I'm no expert, but I think the input impedance has a lot to do with it.

Input impedance huh?
The same guitar going through the same cable going through the same pedals at the same settings would have a fixed amount of input impedance. If what you suggest is true, if you plugged that very guitar into a dozen different amps they would all take to pedals in EXACTLY the same way because the input impedance is EXACTLY the same. Hardly.

Sorry, that just doesn't add up to me.
That's strange. It's my experience that plexi Marshalls take pedals better than any other amp I've played. However, if you are plugged into the bright channel of a Superlead plexi it will be too bright for a lot of pedals, try then Normal channel.Originally posted by johndara
My Traynor YCV40 takes any pedal I put through it beautifully. On the other hand my Marshall 1959 Super Lead (non-master volume) won't take any kind of distortion or fuzz pedal. Can Anyone explain this?

Thanks to all that responded to my question, I actually gained some knowledge as to why I'm having a problem with pedals through my Marshall. I'm going to go with what Paul C. said about the bright caps and what PlexiBreath had to say about the the bright channel of my amp. I may change the cap on the bright channel and also try using the normal channel. Thanks again guys, and by the way Paul, Tim and Timmy are both the best clean boost/low gain pedals I've ever used, your a genius!!

Actually no, I only said to use the normal channel as a quick fix. You can peal back some of the brightness of the bright channel and it will still sound sound like a superlead Marshall, just reduce the value of the treble bleeder cap around the volume pot to 680pF, then insert a 180K resistor in series with it, then locate the resistor/cap right off the wiper of the volume pot, lift one side of that cap and insert a 150K resistor in series with that cap, (I've played around a lot to determine these values), this will reduce the effect of those caps, but not so much that it no longer sounds like a Superlead, pedals will sound better. But before doing this just plug into the normal channel to see what you think, there is really very little difference between the bright and normal channels, tweaking a few components in that area and you can dial in the sweet spot. But if you don't know how to work on amps have a pro tech do it for you.Originally posted by MikeyG
This would be a conundrum for me, beign that I like the Bright channel of a Marshall better. I couldn't do that, because I wouldn't have the tone I want with the pedal off. Then the question becomes "which is more important to you, the pedal or the amp?"
