Groove Tubes power tubes are matched and rated in low, medium and high output levels. Most amp manufacturers bias their amps for tubes in the "medium" range and replacement of stock tubes frequently do not require re-biasing if "mediums" are purchased. For softer feel, quicker distortion and creamier tone, They suggest "lows"; for more dynamic headroom and tighter, quicker and harder overall response, They suggest "highs". Lows and highs are more likely to require re-biasing by a qualified service technician to meet your performance preferences.
