I have a little Top Hat Prince Royale 1x10. Its a 4 watt single ended EL84 powered amp. The Bright switch when set Bright is too harsh, but without it my humbuckers are a little dark. Now Im quite a novice, but I can see the Bright switch when set to bright seems to remove a small yellow capacitor from the Volume pot. It reads 150m .0022UF 15%, 630v 9330. Dont worry, Im not going to poke around in there as inexperienced as I am. Would my amp guy be able to change that to a capacitor that is less of a drastic filter? I guess he could even put a tone control (on the bottom of the amp unseen). What do you think? I believe this amp is based on an old supro????
