Rat is king, but I'm considering the following: Boss OD-3 Subdecay Liquid Sunshine Way Huge Saucy Box Blackstone Mosfet Maybe a Timmy, but apparently they don't seem geared to go with a Fender amp? I built a Bluesbreaker/PoT pedal for someone not long ago, and that was pretty neat so I might go in that direction too. I tried a Mad Prof Honey Sweet Honey ages ago and quite liked it, but it didn't have quite enough gain and was a little uninspiring. Same goes for the Klon actually. Just kind of boring. Or is all this fairly pointless, and the real key to this having the amp on the edge of breakup?
