With this SVT-CL that i have, it is "clean", but it is "woofier" than the SB300, i have not looked in the SB300 to see what pre tubes are in it, but in the CL, i had in some Ei smooth grey plates with hello getter pre tubes, some GE 12AT7 (matched) for the bias circuit and the inverter tube is also a Ei 12AX7 as well. It stays clean, no rasp or overdrive to the point i can stand it.. the power tubes are Sovtek 6550WE (matched). I can't stand the amp past 10 o'clock on the master with the gain between 9 and 10. The SB300 is just as loud but a tad bit tighter, meaty, sounds like it has weight.. so does the CL.. but just not as smoothly heavy as the SB300 is.. the way i put is that the corners of your mouth will look like they are tied to your ears all night long!
Awesome!!
Thanks so much!
