Mesh,
Recabinet sounds good. I got it for $29 at the last sale.
I'm sure R4 will sound better. The BIG question is...
WHAT WILL THE AMP SIM sound like?
The upgrade price to R4 is $29 and, with the Amp Sim and ALL MODULES
released for the next 2 years is $79...so that seems reasonable.
It will seem more reasonable if the Amp SIM lives up to the hype...
