Hello To all. Just paging everybody to let you all know that I just recieved my Carvin RL1018. My first Impresions: Contruction: 4.9 Out of 5. Just Excellent. I would have liked a little acoustical bating inside the cabs. Althought the controls are very intuitive for me, the first sound I dialed out of it sounded like CRAP. I was very upset by this, because I expected a really great sound from starters, also, I had a lot of distortion coming out of the amp. Suddenly, I remembered that the R1000 head has a mid cut by default in the low midrange section. I adjusted the gain controls until the clipping light dissapeared conpletely. I hit the Low Switch and Midrange Shift, put it at full range, bot amps at 5 and the Master Volume at 3... then.. BOOOM!!! --- Very good sound. Happy with it. The highs were harsh, so I turned off the tweeter. Not good, not my sound. So I put it at -3dB. Perfect. ---- UPDATE: It wasnt the tweeter, it was the frequency points of the AMP, It shoudl have EQ at 8Khz and 10KHz, I like that frequencies for a crisp Sound. I use the tweeter now at FULL ON. and boost the highs on my bass (10Khz) to get the crisp sound I crave. Carvin should use a higher powered tweeter and a Higher crosover point, so the tweeter doesnt get any high/mids but only real highs. I think I will buy a couple of Piezo Tweeters to compensate or posibly put an Eden Crossover and Tweeter instead. Then I started checking the Biamp settings. Usable definetly, at 200 at least and maximum at around 600/700 Tube sound? Yes, it can be dialed. It is no SVT, but sounds very nice. I added more "Tube" blend on the preamp, I lost some lows but gained a very barky pick sound (I dont use a pick but had to try it) Efficiency: the RL410T is good on the efficiency deparment, lacks a little lows that were compensated when I put the cab on the floor and bridged the amp to boost 700Watts to only that cab. The RL118 however,is not as efficient as expected. But sounds very good WHEN mated with the RL410T. Does it sound very good? Yes. Does it compare to Eden? No.. Would I use Carvin instead of Ampeg ? I am. I would have paid double for the Ampeg rig I wanted, but the Carvin surpasses it for less money, and of course has more power. Has the lows? Some, the RL410T lacks some authority. Also bass projection is not very focused. Has the Mids? Yes. Fingerstyle Kind! Has the Highs? Moreless. I think the crossover point in the RL410T should be higher, and that the horn should handle more power, it gets harsh too easily. Am I happy? Yes. But I still have to try it with my band this sunday, so there is more to come. I will continue experiencing with it, and read some of the manual before I continue. Would I recommend it? Yes, for the money, it is indeed the best amp you can get. Of couse, If you have the "extra" money, get Eden Cabs. The R1000 Head is just beutiful, and I dont think there is a match in terms of Value and Sound together.
