Ok, I have an Ampeg SVT-350H with and SVT410HLF cab, and I can't seem to get my E string (yes, I only play a 4 string) to come through as well as the other three. I'm not really used to the Graphic 9-band EQ, and with my old amp you had to set everything at 10 to get any kind of sound out at higher volumes, so I don't really know what the deal is with the 3-band either. I like the sound I get with the higher 3 strings, but I can't get the E string to get the same "punch". I tried searcing for a similar thread, but with no prevail. HELP PLEASE!
