"рThe RR1 is a faithful, uncanny, solid-state tribute to one of the worldуs most renowned D-style tube amplifiers,с says Retro Channelуs Lance Keltner. рThe amp that we emulated was known for itуs incredible harmonic content, unmatched touch-sensitivity and beautiful tone.с The RR1 uses a proprietary, solid-state chip so players can enjoy the best possible touch-sensitive tube tone. The RR1 controls are Bass, Middle, Treble, Volume, Presence, and Master, while the rear panel has a dedicated line out, speaker output, effects send and return, and Resonanceяused to the fine-tune the amp to work with different amps."
