Hi guys I recently aquired a Rectoverb combo version 1. It's a decent amp but ever since I got it the solo boost hasn't worked.(got it Friday)I plan on bringing it to a Mesa dealer for work but I just want to know if this a common problem for these amps. Also the reverb tank came with it but is not in it. I got the amp from a local guy but he has only had it a short while and sold it cause he needed the money. He told me the tank was shot but when I asked about the boost he said he never used the footswitch so he didn't know about it. I'm not really going to hold him to fix it I got a good deal I think? I paid $300.00 for it. Not really a big deal on the verb as I have a reverb I can run in the loop, however the boost needs to be fixed. I'm pretty sure this amp is fairly old its serial number R50 00658. I'm not sure what year it is and I haven't had any luck finding info on these. Any help would be awesome. Thanks!
