Pedal-testing amp selection - completely different results

motterpaul
Okay - Of course I know that every amp sounds different (duh)

But I am really pretty SHOCKED at how much different my current (new) pedal testing amp sounds than my previous.

Before, I had a simple 30-watt tube amp - and I dialed it mostly with everything straight up except some treble, presence and reverb.

So - I just transitioned to the Marshall  JCM800 2204 (single channel "classic" tube amp). The 2204 is considered to be one of "the" most classic amps for using pedals. If a guitarist plans to go the pedal route rather than with tube overdrive route - many people highly recommend a JCM800.

I am using the same speaker box, mic, etc.

Well - geeze, so many of my pedals that used to sound great with my old amp now sound completely different - it really makes me wonder. My JCM800 is a classic, you should hear how sweet it sounds just on its own. And I put in two =C= EL34 power tubes and a Mullard & Amperex preamp tubes, and a Phillips 12ax7 pi. It sounds awesome.

But for pedals - just so much different from what I expected. I actually find that (too) many pedals I loved before (using the smaller amp the same way) I don't love so much now. But I spent some time dialing in (meaning trying different components for the tube stack) a new fuzz circuit I have started using and it sounds amazing.

Now - you have to crank it to really get "the tone" out of it, and I am still using my DAW setup where I have the amp going into an Iso-box where the speaker (Gold Alnico) is miked by an SM-57. I monitor that through a pair of small KRK monitors - which is cool because what you listen to is that "studio sound" of a miked guitar amp with the pedal you just built.

Still - I am just shocked at what a difference it makes - especially on overdrives. The tone is completely different.
