I always found that my Washburn dread sounded amazing for the price, but a little dead and mellow on the low strings. I also do prefer light strings but thought 11s are plenty light for an acoustic. I already thought about upgrading because I just love bright, open sounding, smashing acoustics. But I went down to 10s on it yesterday, and now am in love again. All the tone i ever wished for. Nice bright sparkly lows and soft highs. She just feels alive now. Anybody else experienced this phenomeon? She's not going anywhere now!
