AMP HEADS

Progressive, practical designs that are tipped for the top

PRS MT15 MARK TREMONTI SIGNATURE HEAD £555

PRS has really gotten serious about its amps. The twin-channel MT15 is a case in point, with hand-wired output valves for reliability and boutique touches such as the amp’s interior lighting changing from blue to red when you change channels. The cleans are punchy and adaptable, while the gain tones from this lightweight, affordable head offer “a stunningbarrageofharmonicfilththatflatterseverynoteandpowerchord.” www.prsguitars.com

ORANGE ROCKER 15 TERROR HEAD £549

Orange’s amp designer Adrian Emsley has developed the perfect small classic rock head here: squeezing fat, harmonically rich drive tones from a brace of EL34s, the Rocker 15 Terror has a Natural channel offering chunky, power-valve clipping, while the stonking Dirty channel opens the door to a furnace of hotter gain tones. With power attenuation letting you step down the power from 15 down to just 0.5 watts, it’s practical, too. www.orangeamps.com

POSITIVE GRID BIAS MINI GUITAR HEAD £876

Heads have evolved from behemoths of power to the lightweight alternative to a combo. The Bias Mini is perhaps the ultimate extension of that idea, packing in 300 watts of Class D power and 16 compellingly detailed amp models into a head only 4.6cm tall. Tellingly, the cleans are as good as the driven amp sounds and the Mini’s high-quality reverb ensures it works superbly straight into a cab, desk or PA. www.positivegrid.com
