Now This, Is Orange
I own a Custom Shop AD50 and it's the precursor to this amp. Had a chance to play the CS 50 at length through a matching Orange 4x12. Fantastic clean to rock single channel amp. Has a master but only sounds better in a non-master type way as you crank it up. This is not a bedroom amp unless you had a good quality attenuator. Still sounds fine using the Master lower but glorious if you turn it up. Presence knob has a subtle sweep and didn't notice it getting noticeably more aggressive above 8 as Orange says it would. The amp has plenty of top end with humbuckers so it wasn't really an issue. I see a lot of demo's where they crank the gain but don't lower or kill the bass to tighten it up. It can get wooly with the bass up but if you have the Master and gain high, kill the bass and you have a nice, tight and percussive rock tone with plenty of body. I didn't try the boost but imagine it's the same tone stack lift my AD50 has, which sounds OK for higher string leads but gets a little muddy for low string riffing. If I didn't have the AD50 I would be all over this amp and honestly may still get one anyway. Highly recommend it to anyone wanting a dynamic, plug in and go rock machine.
