I am thinking of buying a Carvin Rig: R1000, RL210T & RL115. Carvin may be a well known name in the States but are very rare here in England. I am attracted to this setup because of its power coupled with portability (im getting a bit old for lugging large cabs up stairs). I have read many reviews about the equipment; most of which are very positive. There appears to be a good range of control and most reviews are complimentary on the sound: this is important as there is only one supplier in the UK and I will not be able to try before I buy. On the down side, I have read a number of reports of poor reliability of the R1000 head. Are there any views out there?
