Couldn't say for sure but it might be ok if you use it with the clean channel, Satriani (pre peavey) used one as his main drive tone into a clean marshall. If you're demoing it I'm sure most guitar shops will have a fender amp to try it with. Mine is (was) used with a Laney pro tube 30 watt 12" combo and it works great, can't really do thrash or scooped metal (too fat sounding, but my old digital metalizer does that) but I was really happy with it. I tried a Keeley too, good but even fatter, if your amp is quite bassy it might be too much, if your amp lacks bass get a keeley!
