I haven't been able to read through the lengthy thread, so my apologies if my question has been asked before.
Has anyone done the "LED Mod" whereby two red diodes are desoldered or clipped off? Supposedly this gives the amp more headroom, and less fizz with the boost on and gain at full. If so, can you give feedback/confirmation on the mod's effect.
I would rather make it switchable, rather than a permanent mod, tho...
