That surprises me Dave, I thought you were well into the Mule.
Well it worked really well in a Gordon Smith I used to own, but in a Les Paul they've just not worked for me. A bit too bright and thin sounding in the bridge, especially in my Gibson LP but that is a bright sounding guitar to start with. I'm still undecided on the one in my Tokai. The neck pickup is an AIV Stormy Monday and isn't working at the moment, plus the bridge tone control is hit and miss, so I've got parts on order for a complete re-wire to hopefully fix it.
The Riff Raff in the SG is great though, perfect for rock tones.
