FDP Forum / Fender Amps: Vintage (before 1985) / My silverface Champ is LOUD

I've had three Champs over the years but never had one as loud as the one I own now. In addition it's got great breakup. According to my memories the other champs I owned were not particularly loud and stayed pretty clean up the dial. This amp was completely serviced by the last owner and has a Warehouse veteran 20 speaker and vintage tubes if that helps. I'm not complaining just scratching head.

About as ordinary as you can get.

I have a silverface Champ and a Vibro Champ and both are fairly loud. Great amps in my book.

I used to use a little 1971 SF Champ with a 6" speaker for band practice. This was with a full
drum kit, a bassist with a 500w amp, and a 2nd guitar player. I never had to dime it, and we practiced loud.

Some get ridiculously loud. You could easily gig a small club with one.

BF and SF Champs I see virtually all still have the original filter capacitor can , which has a service life of about 15 years. Some work great for much longer, and some weaken the amp. And some blow, sometimes burning out the power transformer.

But "loudness" of Champs depends on several things - the condition of the filter caps; the power tube type, strength and the condition of its cathode bypass cap; the preamp tube gain; speaker efficiency (a huge factor) and the output transformer (they're not all that consistent).

A qualified amp tech can optimize any tube amp and help with replacement speaker selection depending on what kind of sound and breakup level you want.

But most players only take an amp to a tech when it has problems, not for regular service every 15 years or so (filter cap replacement, other parts and voltages checked with parts replaced if seriously off-spec, pots and jacks cleaned and lubed and tube sockets checked & re tensioned if necessary)...

...and rarely for "optimizing", which can make a huge difference in how an amp performs on stage or in the studio.

I had a cherry sf Champ and V Champ. Recapped them both. They sounded great.

I sold them both.

What a friggen dope.

Perhaps the Warehouse speaker is more efficient, all other things being equal.

Silverface nailed it. It’s a well set up amp. And I agree with Roly, too. That speaker is probably part of the equation.

I’ve got one of these (see link) which I might, at some point, pop into my newly-acquired Bronco.
