Most (if not all) combo amp/speaker units are a compromise in one way or another. Either the unit is too small to deliver enough punch or is too big to be easily carried around. This is where the Marshall VS65R hits the sweet spot.
The 2 channel (clean and drive), 65 Watt Valvestate and 1x12" speaker combo along with built in spring reverb delivers enough to be a great practice and home studio amp all while being compact and light enough to take on stage for small to medium gigs.
Treble, Middle and Bass controls and a Tone Shift switch for tonal options on the Clean channel are enough to tweak up a decent crisp sound. Gain, Volume, Treble, Bass and dramatic Contour control on the Overdrive channel are dynamic enough to cover most playing styles needing overdrive.
The Headphone jack which mutes the internal speaker is perfect for practice sessions at home (when you don't want to wake the neighbors) and the Line Out jack is well suited for connection to external equipment such as effect units or recording setups. Foot switchable channels is a great feature.
All things considered, the Marshall VS65R combo amp really hits the sweet spot by delivering a great sound in a very portable unit... and at it's price, is really is a great buy.
I bought my one used, great clean sounds with several guitars of varying quality. But seems to lack a beast mode, even with an array of effects plugged in. The dirty channel has very little punch, even at big volumes and can be quite bassy and muddy, again tested with several guitars.
