I recently purchased one of these little amps (haven't received it yet), and while researching it came across the common complaint of too much treble. I want to do the C19 (remove from circuit) mod, but was on the fence whether or not to put in on a switch as some have. Has anybody swapped out the toggle switches so drilling a hole in the chassis for a new micro switch would not be necessary? It would make more sense to use a 3 way switch to modify the "bright/thick" to bright-C19 lifted-thick. and while you are at it, replace the power toggle switch with a 3 position one wired to "stand by" in the middle position. Anybody have any experience doing this or know someone who has?
