Orange Rocker 32 Preamp Standalone

[bowenorange]

I have used an R32 stereo for several years. I input guitar into a Boss GT-1000 and output stereo into the two R32 FX returns. It sounds fabulous. This completely bypasses the preamp. I have recently experimented with running guitar directly into the preamp of the R32 to get that nice tube compression and out the R32 FX send to the Boss GT and back into the two FX returns. I like this preamp sound but would like to have the R32 Tube preamp as a standalone box /pedal when I run the Boss GT direct to the PA and dont take the whole amp to shows.

I could purchase such a thing or have one built.

Suggestions?
