Hi guys and gals. I am having trouble finding a good setup to practice my metal riffs at a low volume. my marshall 2x12 amp has way too much thump, and my little roland microcube has NO thump. i use the killer Z (metal zone) setting on the PODXT with both, and it sounds ok. i wonder if the digitech deathmetal pedal would be better. let me know if you guys have any ideas for a solution to my problems. thanks
