Looking at a classic SVT, had a question about compression... I use an MXR Bass compressor with my shuttle 9 to even out levels between strings. I use 4:1, the lowest setting. Running an SVT, and I like some grit so I'd expect the gain to be up a bit, would the tubes give me a similar level of compression? Never rolled with an all-tube amp...I'm not looking for a ratio, just a sense of whether I'll want to hang on to my MXR or whether the tubes will balance out my string levels for me.
