You could even fit a small trim pot rather than a fixed resistor, so you can adjust the brightness as you wish.

Yep, that would work a treat I'd most likely use a ten-turn trimpot of at least 100k in value cause I think the Blue led in the amp already has a fixed 47k current-limiting resistor, I've got a nice Jensen C10Q speaker to put in the amp, I just need to find some spare nuts that'll fit the speaker mounting-bolts cause it's missing three of them.
I've found that in practice those modern super-bright leds don't need a whole lot of current to glow at full brightness, less than a milliamp.
I just checked the led's current-limiting resistor and I did indeed use a 47k/1% 1/2W metal film resistor.
Okay, I have to be honest here, I added the blue indicator led because I wanted the amp to look cool, not me....I'm the complete antithesis of cool.....hahahaha.....

Update:
Just been working on making the new footswitch for my Peavey Backstage Plus amp, seems to have gone without a hitch, but I won't know for sure if it is working properly till i finish working on the amp itself.
Update:
Finally finished all the restoration work on my Peavey Backstage Plus amp this afternoon, everything seems to be working great, including the footswitch.
