I do like my effects. So much so, I've been using an HD500x for the last 5 years, plugged in to the effects return of my amp.
The HD's only just been upgraded to a POD Go. Helix sounds on tap, but with a few limitations. Sounds wonderful.
There's an SVT 4 ini the For Sale section. Though to be fair, it doesn't look much lighter than an all valve SVT.
EBS Fafner?
EBS HD350?
EBS TD650?
Handbox R400?
If you play the MM more than the P & the J, then why not sell them to fund another MM.
However, it might be worthwhile taking your time finding a new MM, try out a few before buying another one.
First rehearsal with the POD Go the other night, very pleased with how it sounded, though a lot louder than I thought, had to rein it in somewhat.
Made a few tweaks on the fly, dead easy.
Overall, very happy with it. Sounds superb.
