The Blackstar HT-5R MKII Tube Combo Amp takes this revered design a step further with incredible performance and game-changing new features from dynamic power reduction to 0.5W and footswitchable voices, to XLR DI out and direct USB recording.Low Wattage Valve GoodnessThe valve amps sound best when cranked. The unique feel, dynamics and natural compression of a valve power stage running hot are widely considered the holy grail of guitar tone. The HT-5R MKII with its low-powered push-pull 12BH7 power amp produces the crunch and break-up characteristics of a traditional 100W output stage, at volumes suitable for home practice and recording.Professional Recording ConnectivityThe USB output has been added for the simplest way to get valve tone into your recordings. Also added is a pro balanced XLR D.I. output, which allows the speaker simulated signal (selectable choice of 4 x 12 or 1 x 12) to be connected to external devices for practicing, recording or live use.Power ReductionInspired by the patented Dynamic Power Reduction circuit, simply switch down to 0.5 Watts at the push of a button without any loss of tone. It is perfect for driving the 12BH7 power stage hard at lower volumes.Patented ISFThe patented ISF (Infinite Shape Feature) control is unique to Blackstar Amplification and represents a major step forward in tone shaping flexibility. The ISF control shifts the response of the three control tone stack between, a US type response at one end, and at the other, a UK type response. Importantly, in between the two extremes lie an infinite number of alternative tone choices that would be otherwise unavailable.
