Ok So I understand that the 5150 and the earlier revisions of the Dual rectifier 2 channel are based on the soldano SLO. I am very interested in this amp and its tone I found a couple soldano Hot rods but I have seen on this website that those are very expensive clones, The Jetcity jca100 H seems to be the cheaper alternative if I am after the "Slo" tone? Is the Slo easier to find then an early revision of the Dual rectifier with the awsome pre 500 tone? Is the reason a Dual rectifiers sound so good with a 5150 because those are two sides of the same coin and you are basically making up the best parts of the Slo that are living in those 2 amps? Currently I have a Mark V and I am looking to find an Amp to add to my collection and to compliment the Mark in the recording studio. I feel like the Slo is the amp todo this but is there a way to maybe squeeze a good Slo tone out of the Mark V Keep in mind I have never played a Slo in person the closest experience I have is a few soldanos in stores for maybe like ten minutes no idea the models I think one was an avenger and the other was a hotrod possibly and I only spent maybe 10 minutes at most with those amps. My other idea for recording purposes mainly is getting a 5150 block letter and a good dual rack mount rectifier. However I couldn't use all that live when I get into other bands down the road. Suggestions pleaze I am trying to stay away from 3 channels and roadsters because I think those sound best with EMGs and boosting which I would like to avoid doing.
