An amp with lots of gain always has lots of residual noise, right? Wrong! Enter Rocktron's exclusive patented AGX circuitry. The AGX (Automatic Gain Expansion) system solves the long standing problem encountered by guitar players when using high gain distortion. The AGX circuitry expands the gain of the amplification circuit only when required based on the input level. When no signal is present, the AGX circuit expands down the amplification level to a point where "hum" and "noise" are dramatically reduced. Let ‘er rip at high volume without the usual residual noise. In live situations, in the studio and at home, Rocktron's Rampage Series Amplifiers delivers the sound and the output that is Rocktron's hallmark. The RT80's sound can be contoured to deliver the crisp, shimmering clean tones that are a staple in pop rock to the heavy, saturated and destructive sound of mega metal. Check out the middle ground - the "heavily-driven tube" sound and the huge "mushy" and "wide" sound of today's modern music is right at your fingertips. Best of all you can get "your" sound - if you want to sound like someone else you can, but when you are ready to create your own sound it's just a turn of a knob away! Guitarist Magazine (UK) wrote: "Using the high input, the clean channel is bright and modern with a hard edge. Opting for the low input warms things up slightly. Switch to the drive channel and you're knee-deep in thrash. There's bucketloads of gain on tap and Rocktron deserves a pat on the back for putting it there. I'm for a party engage the mid scoop and you have a sound any self-respecting mauler would be proud of; simply preposterous amounts of gain coupled with all the boom and fizz you can imagine."The Rampage RT80 has a built-in Chromatic Tuner, allowing you to tune your guitar without unplugging from your amplifier. Wrap it up with a solid, heavy duty, open backed cabinet with a durable covering, corners and handle you and you have an amplifier that will "kick butt" in all playing situations
