Is there a way to do a high-cut mod on a B52 combo? The poor man's Dual Rec

It's basically a 60watt all tube combo with a Mesa Rectifier type circuit, made in China. It's my go-to back up amp and it needs to lose some horrendous top end. It's a 6L6 powered amp, thanks much.

Do you have a specific model #? A schematic would be best. There are tons of simple ways to reduce superfluous hi-end in an amp. Only problem is a lot of those cheap amps can be hard to mod and work on in general.

Yes of course, it's an AT112 -but I could only find the manual on-line.

Man, I can't seem to find it either. Really hard to recommend any mods without it...
