Greetings, fellow bass enthusiasts. I have an Acoustic 370 that no matter what, I can't get the brightness out of the output. I've replaced a couple of the bigger caps like the supply voltage and the output cap, but can't get the brightness out of it. Any suggestions? I'm thinking of getting an Ampeg SVT-350 but don't want to give up on my old 370 just yet. Thanks, guys!
