Alright, I need your help on this one. I have an Epiphone Casino, and a Vox AD30VT amp, and I was wondering if anyone had any tips to get that John Lennon Sound around The White Album/Abbey Road, and especially Let It Be era. If you want more specifics, listen to "Dig A Pony", "Don't Let Me Down", "Get Back", and that's what I'm really looking for. That crunchy, dirty guitar sound. I've messed around with a bunch of settings, but I can't seem to find the right ones. Any help? Thanks!
