I got a Ibanez ICX220 for christmas with a DigiTech RP50 and a Laney KD65 (like a 16 year old amp that i found at my grandads). Recently i've been getting annoyed with the sound i'm trying to get, wither it be a master of puppet sound, or a heavy slipknot distortion i just can't seem to get it. I'd like to upgrade either my Rp50 or the amp, or if there are any pickup upgrades i could get for my ibanez. All help is appreciated

I think you'd benefit more from an amp upgrade. What's the budget?
