1) After changing out your tubes, is the difference supposed to be a subtle difference, or a quite noticeable difference? For the first time, I just changed out the tubes of my Peavey Classic 30, which btw wasn't all stock as I had thought, but had a lot of random tubes. I saw a Mesa Engineering power tube amongst some other weird tubes while I was changing them out. Anyways, I bought a new set JJ tubes from Eurotubes and installed them. I noticed a difference, slight warmth and mellower sound, but other than that, there wasn't really much.

2) My volume pedal doesn't mute the sound all the way and makes a weird crackling noise every time I sweep it. It happens mostly during mid-sweep. I've put some of the contact cleaner that I used on my tubes onto the things inside, but I that didn't help it at all. What's wrong with it? Its an Ernie Ball Volume Jr I believe.

what I notice about my JJs is you get some more clean headroom, if you are playing at a loud volume and are familiar with how it was before you should notice a difference there. there are other things that are different but as far as how much you'll actually notice it's kind of subjective IMO, but I'm in no way a tube expert.

The volume pedal issue could be any number of things, power source, bad cable, loose connection somewhere

Also the tone of changing tubes really depends on a few things
1) How old the tubes already in the amp are
2) Some have very similar tonal qualities, others like Tung Sol (bright) vs JJ (dark) will be a much more noticeable difference.

I dont have much experience with volume pedals, but looking at reviews online it seems that many people have had similar issues with that model.
If you dont mind dishing out the cash, I think an active one will serve you much better

it really depends on what tubes are in there already... it could definitely be a subtle change.

if you want a bigger improvement, maybe swap the speaker? i haven't done a speaker swap on a c30, though, so bear that in mind. normally it makes a pretty big difference.

I saw in a couple of pictures that on Bucketheads Les Paul (only some pictures) that his neck pickup is painted in white. Can anyone explain to me why he would do this, and if there are any pros and cons.

The guy wears a KFC Bucket and a white mask during performances, and you're interested in the color of his pickup covers?

Whether you hear a big difference or not depends on what you are replacing with what. If it was loaded with 7th generation Shuguangs and you replaced it with Gold Lions and SED then you'd pick a big difference. JJ's would be very noticeable too. If it had some good tubes in there already then the difference will be much smaller.

These were the tubes in my amp before. Like I said, all very random and not stock as I had previously thought. I know the speaker change was supposed to be a more dramatic and noticeable difference, but I need to save up enough money again to buy that.

How can I fix my volume pedal issue? It's pretty old I think as I found it lying in a box in the back of my church's storage room.
