Yeah, I wouldn’t worry about it too much, you can always trade the amp up for another one later - and, in the meantime, just test out different amps to find one you like!
Welcome to the forum @fabiogrmelo.
Don’t feel bad about the amp. I’ve only been playing bass for 4 months and I’m on my third amp.
So when are you getting a “stack?”
As soon as my neighbors tell me the Rumble 100 isn’t loud enough
I am using a Rumble 40
I keep the EQ all flat at 12 o’clock
I try and keep the gain and volume around 12 as well, then just use the volume on my bass to dial it down if needed, but sometimes I need to back off the gain/volume a little more just so i don’t knock pictures off the wall.
I have played with the over drive and its great… but it rattles the whole room… so the wife get’s a little upset if i go that route. I also like the vintage button, it offers a nice sound. But for general practice I turn off over drive, and do not use any of the modeling buttons.
Eventually i would like to add a nice modeling amp like the Rumble Studio, but that’s down the road.
