Blackstar HT-5R is awesome
I have honestly owned many different amps throughout my life: Fender M80 chorus, Vox Valvetronics & Pathfinder, Marshall AVT150 and Blackstar ID20. This amp was a college gradutation present from my wife and man oh man is does it set itself apart from anything else I have ever owned. This is the first completely tube amp I have ever played and it sounds great. I paired it with a Marshall MG412 cabinet based on a recommendation from a friend and all I can say is wow.
The clarity of tone, note for note, is breath taking, the wide variety of tones that are possible due to the ISF is incredible, and the punch from the 4x12 cab is inspiring. It is true that it is only 5 watts but it is clearly enough for a small gig, rehearsal, practice, or just home paying. The effects loop works great and the modulation of my different pedals comes in clear and with out any loss of power. I run my wah pedal through the front and the other pedals through the back, it works great.
Overall I would highly recommend this amp to anyone who wants a moderately priced low watt all tube performer for small applications. You will not be dissappointed.
