Mustang IV solo/overdrive sound lacking balls

What i found was the V2 series mustangs when turned up really push the hi mids in a big way and also low end disappears. I felt the same as you....at home, great, but with the band it was really thin and harsh and sustain and body just went out the window and it was hard to dial it in to fix all that. What i did that really turned things around was first to use the SS 1x12 cab. It's really dark and muddy at home, but at stage volume it absolutely tames the high mids which are whats killing the smoothness and sustain. But now you have a rather dark dull tone. Step 2 fixes that. A graphic EQ in the effects loop. I used a dano fish and chips They're about $30 online i believe and they work well with the mustang. I took the 200hz slider up a couple notches to get the lows back and slid the 6.4k slider almost all the way up ad the 3.2k about 1/2 as much up. Thats because at stage volume while the mustang sounds really bright, it actually has very little top end, thats all high mids causing that. Now that you took those out with the SS cab theres no top end left to speak of. So in short, the SS cab removes the excessive high mids, and the EQ gets back the lost low end and missing high end in just the right frequencies. Of course your results may vary so you might use this as a base and tweak from there, but that took mine from being very hard to dial in at stage volume to being easy and overall sounding a lot better. Brought back the fullness and sustain and chimey sweet top end that it has at low volume.

 

It's kind of pointless to make a bunch of detailed recommendations without knowing what your setup is. What amp model and pedals are you using and how do you have them set?
