V5 Infinium : Great little amp for Jazz

Bought the V5 to use with my Peerless Monarch (with floating Zoller pu) for practise, recording and small gigs. Out of the box the amp sounds great - tone & clarity is bang on, gives a good approximation of that Kenny Burrell Midnight Blue sound with the Monarch. Controls are straight forward - gain (push this to get a nice broken crunch for a more bluesy sound), volume, tone (basically adds/cuts treble) & reverb. Reverb is digital & gives a fairly good spring reverb sound. Volume is impressive & with the open back you get that nice wash of sound from the amp. The power attenuator allows to switch between 0.5/1/5 watt settings which obviously impacts on volume but also gives another paramemter to play around with for getting different sounds - particularly around using the gain setting. Also has a headphone output - but I find that it gives a fairly thin sound when used. Overall - a great little valve amp that packs a punch volume wise and gives a great jazz feel.
