GHR is the product of Laneys long-term study of how guitar players interact with tube amps. Tube tone is composed with what we have come to describe as RED and BLACK tone elements: RED is tube preamp distortion, in which ECC83 tubes add drive. BLACK is output tube distortion which increases as the power tubes are driven harder. GHR allows the player to balance RED and BLACK elements to seek the sweet spot in each players setup. The result of intensive design and development in Great Britain, the GH50R delivers 50 watts RMS of pure, rich, warm tube power from an EL34 loaded output section. Both of the GH50Rs channels can be configured to be used either clean or driven, with each channel producing subtle differences in tone depending on how you tweak them. This is the amp tweakers delight! Whether its funk or melodic rock, whether youre a hybrid picker or a shredder, the GH50R delivers outstanding, dynamic, complex, rich & colourful guitar tones. The 3 band tone stack is shared between channels giving a simple yet effective tone palette. A Pull Shift function also increases the tonal flexibility of the mid-range.
