The 320 has more features and control in the higher frequencies but the 370 just sounds like classic bass magic. I haven't been able even been able to put any pedals in front of it since I picked it up.
I use them so differently that I can't fairly compare them.
I bought a 370 off of eBay long long time ago. Guy said it worked great. Got it and it did not work at all. Sent it to a shop to have it repaired at the recommendation of a music store in Kalamazoo. Guy went out of business after I sent it to him and I never got it back, he moved!!!! Got screwed on that deal! Was the closest I ever got to owning a 370. I will have one one day though!!
