I have had 8 amps in 10 years looking for "that sound"......... Marshall, Mesa/Boogie, Fender etc etc - spent far too much money.
Bought a Blackstar Artisan 15 a month ago and am ecstatic - it is nothing short of astonishing - build quality, price, value for money and, above all - THE SOUND. Ignore at your peril. Celestion Greenback makes it sing beautifully too.
Audition them before you buy any boutique or mainstream tube amp and save yourself a load of money with a superior sound.
