Re: Randall Amps...
I own the RG100SC, it's a 100W solid state 2x12 combo with Celestion 70/80ies. Great amp for the price with some of the best SS cleans I've heard. It's quite warm. It has an Accutronics reverb tank which sounds very nice.
I don't like the distortion channels much, they have a brutal voicing but not enough gain to play metal or heavy rock. I got some killer tones out of it using a distortion pedal.
Build quality is good, made to take on the road. I have no complains other than screws coming loose a couple of times and the fact that it's quite heavy.
I played the Recto and Blackface module in a RM50 (the 1x12 combo) in a store and I was impressed with the blackface but not with the recto. It didn't seem to have as much gain as I expected but I only played it at low volumes so that might have been the culprit. Sounded pretty good though! I almost bought the 100W head but I ran into a better deal. I think Randall makes some pretty good amps with nice features for reasonable prices.
Hope this helped.
