Hi, i'm getting to know the mb500. Nothing to complain about it, even this i'm going to say: i have a very aggresive fingerstyle. I tend to clip the signal a lot, i mean, almost always. You may not believe me: but i thing it sounds good to me. Neverthless, my natural technique no matter what tends to clip. And yes, i only play passive basses (i can notice how the neck pickup of my jazz bass doesn't clip near as the bridge pickup does). I am playing the amp with headphones or speakers with the line out at home, no cab for the moment. What i found out not to be clipping the amp a lot (on the manual it says to lower your volume, they don't contemplate the option of just letting it clip) is to turn on the -10 db pad. Yes, they say is for active basses but i guess is the only way of not letting the head clip. I notice i need to turn up the volume when i use this but also the gain (by the way, the manual also says this). Is there something i am loosing in my tone by doing all this stuff? I am trying to figure out and sometimes it makes me doubt. But i keep going for one sound to the other by pushing the pad and changing the gain and volume settings so i think maybe an external opinion can help. Having a preamp box (mxr or tone hammer, sansamp, etc) can also work notto clip but my goal is to make everything with the head. Thank you.
