I've got a CR60 with an Eminence version of the V30 and use the clean channel mostly.
The gain channel has Bass, Mids, and Treble controls and I don't have any problems with this channel. This amp also has a clean channel, which has given me some spongy bass, has bass and treble controls only. And if I try to remove the very lows with the bass control, it takes too much out, so I tried my pedals.
There are a couple of things I did to lower the spongyness facor:
EQ - I've got an old Danelectro Fish and Chips eq, Boss EQ, and an older MXR 10 band eq. Settings vary depending upon the guitar I'm using and my mood. They all will cut the bottom out, and sometimes that's enough.
Sometimes more is needed, and I tried a couple of my drive pedals:
Full Drive 2 - yeah, I know this is an old out of date pedal and few use it anymore, and it does a nice TS'er imitation - it does firm up the sound and JOYO makes a version of this pedal.
DLS - I leave the bass on the amp alone and cut the bass with the pedal
And right before covid lockdown stuck, I bought a MXR Timmy, and it works really well for me on the clean channel.
This is an interesting pedal. It will let me reduce the bass and smooth out the highs and can add a bit of compression. While I don't consider it high or medium gain, OD it blends nicely with the amp.
I suspect that a bunch of OD's would work with this amp and maybe a used Boss BD or any of their OD pedals would be a starting point.
