Valves can be mined for an enormous palette of tones, but most amps leave you with just a Master Volume dial and one choice of valves, making it all but impossible to experience these varieties at anything less than titanic volumes. Enter the Bugera TRIREC Infinium - this all-valve tone buffet features a Varipower dial that scales output power from 1 to 100 Watts, giving you sweet power tube saturation at apartment-friendly volumes. Feel like experiencing a power valve variety besides 6L6? Infinium Valve Life Multiplier technology not only extends the lifespan of your output valves, it allows you to run all 6L6s, 6550s, EL34s, or you can mix any combination of the above to create your own signature tone. The TRIREC also gives you three preamp channels, each with a wide array of sonic options, internal reverb, an adjustable and remote switchable boost, an FX loop, and three rectifier modes to choose from (valve, silicon diode, valve and silicon diode). Tri-What? Rectifiers convert alternating current (AC) to direct current (DC), giving your guitar amp the power it needs to rock. Most of today's amps feature solid-state rectifiers, which have high power output and tight bass response. But many guitarists prefer valve-based rectifiers, which are known for their "sag" effect - this basically means when you slam a chord, it doesn't reach its full volume right away, but instead makes a tough initial impact before quickly blossoming into a classic rock ultimatum. With the Bugera TRIREC, both breeds of rectifier are alive and well in the same amp. You can even use them at the same time! Choose Silicon Diodes for high power and tight bass, Valves (2 x 5U4 valves) for lower power and the almighty "sag," or a combination of the two called Valves & Diodes for medium-powered operation spiked with equal parts punch and vintage grace.
