Gauges 011-015-024-032-042-042 Alchemy - a coated string with life in it's tone, not just a long life. Dean Markely's latest string innovation is Alchemy, a new acoustic guitar string line designed for exceptional beauty, tonal accuracy, and extremely prolonged string life. The Alchemy string line's magic comes from Dean Markley's proprietary string compound and process. Alchemy strings possess super sensitive tonal qualities; have a clean and bright sound, and a smooth and easy feel. The GoldBronze are bright and powerful and work well in live settings. The bass is round and supportive sounding, the voice separation and tonal balance is superb. The gold adds a contemporary look and feel to the strings. Not only do they sound and feel good, they also look great on your instrument.
