Ampeg SVT-CL

I have recently purchased a SVT-CL and was wondering if it was ok to use the unpadded (0) input using a Musicman HH 4 string, if so how hard can you push the gain, so far I have had a quick try in the 0 input but mainly been using the-15 input, secondly being new to valve amps, I have been having the gain set at 8 and I don't seem to get a dirty signal, again should I be using the 0 input? any advice is apprieciated.
 
my stingray has about the same output level as my passive basses so i never use the padded input or pad switch on any of them.

John, always interesting to get your input/output on all things bass (and Ampeg.) Do you have a newer EB MM 2 band, 3 band or vintage pre EB MM? That 3 band pre on my SR5 is way hot and I can clip out the Heritage CL Pre to the level of ugliness (even with the 5751 in V1.)
 
try turning the bass down, mids and treble up.
the sound is also dependent on the cabinet you use, playing my svtII through a 2x15 cabinet it sounds kinda scooped in the mids, playing through an 810...sounds perfect.

try bass in the 10-11 o clock range, mids in the 3 oclock range and treble straight up to the 3 oclock position.
then play with the gain and master volume.
ultra lo and high turned off.
mid frequencies in the 1 or 2 position...

it'll be loud but it should break up some...
 
The distortion comes from two sources in a CL...turning up the preamp gain really high, or turning up the amp ridiculously painfully loud so the power tubes distort as well as the preamp tubes. I have played basses that didn't have enough output to get a good head of preamp distortion by cranking the gain, though you can almost always get at least a little with most basses. But if you're not, you can get hotter pickups or add a boost pedal that can drive the preamp harder. Or just get an overdrive pedal...that's what I do. If you want to switch between clean and dirty on a gig, it's the most practical way to do it.
