Been after one of these for ages, since before I got the 502, because it was ideal for my dual rig with stereo amp thing. Course got rid of the bass pre and stereo amp to go with at this point.
Snazzy case, could do with a flap on the back so you can leave it in and get at the sockets.
Pretty much same controls as Pro502 dirty channel, but some levels switching options.
Plenty of options on the back.
Tidy wiring, but a PCB.
With the valves out to show the population of the PCB. Tried it into reverb return of a Sound City, seemed a bit weak, only Sovtek valves in there so prob not originals, gotta get them checked and see if they are the weakness.
