I should try that the next time I whip out my system. It does have a metal zone OD/DS section. Theres actually an EZTone and at least 2 bass/guitar sim presets. I tweeked the EZTone one for a really interesting "death metal" sounding thing. As far as getting a list of effects, check out the manual: http://www.bosscorp.co.jp/products/en/_support/om.cfm?ln=en&dsp=0&iCncd=3421&iStcd=4 Chapter 8 is the guide to all of them.
