Just a quick question about the "Big Muff". Do you need to use it with a tube amp or can it be used with a solid state amp? I usually use a GK MB210 combo combined with a 210MBE or 410MBE. My other set up is a Peavey Tour 450 used with the 410MBE or the 210MBE stacked with the 410MBE. Thanks for any info.
