Looking at your settings, I'm convinced that my unit was faulty because at that volume setting the speaker was farting and a rasping noise was present.
Can you test this out for me.
Use channel 2,turn bass up full and treble on 3. How far can you turn up the volume before the cab rattles and the speaker farts. I got to number 3 with a Pbass.
Thank you.
I believe it was your order. 🤠
It's a pity it didn't work out the way I wanted. I'm still on the look out for a gigable 50w bass combo.
There is an Ampeg PF50 near me for sale but I doubt it will stand up to regular gigging without some kind of case / rack that will add more weight and size. The Fender ticks all the boxes except sound.
