Bachus, I didn't mention anything about upgrading from a 950 to a 970 - that just ain't gonna happen, at least for the most part. However, those that are still playing a 900 or 910 would likely jump into a 970, which would be a big upgrade.
All the best,
PSR-S950, TC Helicon Harmony-M, Digitech VR, Samson Q7, Sennheiser E855, Custom Console, and lots of other silly stuff!
