About 12 months ago I was lucky enough to find a used Carr Sportsman 1x12. I've been playing it ever since and just loving every minute of it. I finally could forget fighting to set the knobs just right on my more modern amps (Mesa's for the most part) and "gave in to" relying on pedals for gainier sounds. I could go back to reference all the experimenting I did over the years and re-build a pedal board that would give me the flexibility I need to be in a cover band and pull in the pedals that I thought sounded best. e.g. Wampler Plexi for crunch, Wampler ego for clean sustain, Fulldrive 2 for cutting through everything and getting great harmonics on solos. As you can surmise by now, I'm a gear head and an audiophile and have been on a decades long tone quest. I can attest that using the Carr as my simple (wonderful sounding) clean base, and using pedals with it gives wonderful results. I can dial in breakup from the Carr to taste given the "headroom knob". Bear with me and I'll get to the part about the DRRI soon enough. Then I joined another band - we play small clubs and these folks only rely on the PA "only for vocals". The Carr (16 watts clean, 19 watts "maxed") is plenty loud enough for rehearsals but I started second guessing whether it would have enough head room for all the different club situations I'd be getting into. I"m sure it would work for most, but that I'd be frustrated at some. I decided I'd try to pair the Carr with another amp - tried a pro Jr but that was a bad idea because the gain pedals push the amps differently. I tried a blues jr and that was much better. Long story short I arrived at the conclusion that stereo was just going to complicate things. I wish I could afford the $2.7k to upgrade to a 28 watt Carr Rambler but sadly that's just too much money for me to invest in this situation at this time. I usually rely on finding used gear and doing trades at local music stores in order to upgrade to quality equipment. The Ramblers are just too hard to find around here. I'm sure it would be worth every penny but I just can't indulge myself to spend that kind of money yet. The first thing I tried was to just bring 1 PA speaker and put it next to the amp and mic my self to the next level of loudness. If the band didn't want to complicate the main PA setup (just a crappy powered PA) then I could just set up my own separate PA speaker and a Sennheiser e609 mic. That worked great but it was still a lot of real estate on the stage. SO Finally I decided to get a DRRI (I've always wanted one) and i had a local sale and some trades that enabled me to buy it. So I get the DRRI home and I'm thinking the real test will be to see if all the pedal settings will still float my boat if I simply swap in the DRRI without changing the settings. Well let me tell you, the DRRI blew my mind it sounded so good and even let some of the pedals do more of their signature tricks (like the harmonics from the Fulldrive 2 through the DRRI are just wonderful - like they were designed to work together). I played the rig through 3 different Tele's, a strat, and a USA Hamer and it held up great. Long story I know but to summarize I will tell you that after decades of looking for the right combinations of gear to get a sound I like, I have to say that just getting a simple classic Fender style amp solves a lot of problems and makes dialing things in a hell of a lot easier. So at this point my plan is to use the Carr for the smaller clubs and rehearsals, and use the DRRI at larger clubs, and experiment once in a while with playing stereo. The fact that I can go between these two amps and not worry about the pedal settings is a big relief. By the way I looked for articles on line to compare the Carr Sportsman vs DRRI and I have not found any good ones. Here's what I have to say. The sportsman is a VERY sweet amp. It can do a lot. It's VERY loud but if your bandmate drags in his 30 or 40 watter and puts it next to you, then all bets are off. But if you are just playing with a keyboard player, drums, bass, singer- it does a great job. And if you want to mic it, then you can use it for any situation you want to. Everyone complements me on how well I can control the volume and I can see the looks on their faces they can hear how how fat and sweet the tone is. As for the DRRI I just got it. It's a different thing. It's clearly louder and just has some great sounds of its own. It's difficult to compare it but I'd gig either of these amps in a heartbeat and I know I would not find myself second guessing my tone (even with a lot of pedals). I wish I was the kind of guy who didn't need any pedals, but hey I'm in a cover band. I need to be BB King one minute and Angus Young the next.
