That's the one thing I wish this amp had. If you do find out what that is let me know.
About the only downside of those old SS Marshall Lead 12s is the pots can get really scratchy. Both on the combo and the heads.
My Lead 100 was like that. Ordered it online and came with scratchy post so bad it felt like sand in them. Flushed them out and they are smooth and work close to new. Luckily the guy who sold the Lead 12 had the pots cleaned recently and they are no problem. Still gave each pot a twist 20 times. But yeah, that can definitely be an issue.
Deoxit and other products work, but it can be difficult to get it int the pots themselves.
Great amps. If you ever get a chance, try it through a 12" speaker. I've posted this here before, but I had Bob at Sourmash build a 1x12 cab which I mounted my Lead 12 chassis into. Sounds amazing with the bigger speaker and cab.
Yup. Had to spray multiple angles trough the hole on the back, and could just get some in the front slot as well. And lots of twisting the knobs.
I loved that when you first first posted it. If I had the extra cash, it would be a fun project. Which speaker did you put in it? Greenback?
If you pull the chassis, the pots have ports for spraying the Deoxit in, directly. Those same ports are probably what lets them get dirty and scratchy.
My Lead 20 gets scratchy but it goes away with Deoxit. Check that the input jacks are snug, too.
I was playing my Tech 21 British pedal through my powered speaker the other night and it was giving my Lead 12/Lead 20 thrills. It didn't look as cool, but us sounded pretty damn good.
I had an original Celestion G12-65 without a home that I put in the cab. It sounds perfect. I do want to try a G12H30 sometime though.
The Lead 12 is a great little amp. I've even gigged with it! In fact I had mine for sale because I picked up a Lead 20 but ended up keeping both cause I like them so much.
Is the 12 able to be quieter than the Lead 20? Also does the Lead 12 have less gain when the preamp is on "10"?
If you mean for practice levels at home, yes slightly. They sound similar to me just a touch hotter with the 20 if that makes sense.
It does make sense. Thank you.
Yeah, that's what I did. I should have been clearer. Back and front of the pots, not amp.
And correct. Definitely what lets them get dirty in the first place.
